Review: Goal Zero Venture 30 Power Bank

Most Rugged power banks are quite large because they have more reinforcement than normal power banks to keep the charger safe. As a result, a Rugged power bank is not only larger than a regular power bank, it is also heavier. Although, there are some cases where a Rugged power bank is smaller, take for example the Dark Energy Poseidon power bank that we’ve reviewed. It is quite small and slim, and yet it holds onto its safety the same as larger Rugged portable chargers do.

This review is about this Goal Zero Venture 30 power bank. It’s quite small that it can easily fit into your hand or even a back pocket, but let’s see what else it’s capable of.


Power Capacity:

The power capacity of this power bank is 7,800mAh and during charging the power capacity goes through a pretty regular conversion rate of 70%. As a result, you’re going to be getting 5,500mAh of power that you can actually use.

Goal Zero Venture for Smartphones

With that said, this kind of power capacity is perfect for charging smartphones, since most smartphones are going to be able to fully charge 2-3 times. Both high and low power capacity smartphones are able to benefit from this power bank.

Goal Zero Venture for Tablets

If you plan on charging larger capacity devices like tablets, then that can be done too, but the power capacity from this Goal Venture power bank isn’t enough to charge most tablets to their full power. It’s able to charge mini tablets to their full power like the iPad Mini 2, iPad Mini 4 or the Galaxy Tab; or at least they’re able to charge near their full power. But if done so, the entirety of the power capacity will be used.

For the most part, I think this power bank has a good power capacity that could last for 1 or 2 days when you’re using it to charge smartphones; that way it’ll be able to provide multiple uses.

Output Charging:

There are 3 paths of charging that are available with this power bank. There are the 2 UBS ports and the Built-In Micro-USB charging cable.

2 USB Ports

Each the USB ports has a charging speed of 5V/2.4A. This is great because 2.4 Amps is able to charge most devices at their max charging speed. That is true for tablets like the iPads that have a max charging speed of 2.4A.

What’s even better is that the max Output is capped at 4.8A. Which means you can use the full power of 2.4A with each of the ports at the same time. So charging two devices at once won’t hinder charging speed.

Built-In Miro-USB Charging Cable

There’s a built-in Micro-USB cable that’s capable of the 2.4A charging speed just as the USB ports are, and it’s basically a way to charge 3 devices at once with the power bank. It’s a very useful aspect for those that own Android devices because you’ll always have a way to charge your Micro-USB compatible devices.

With that said, charging 3 devices at once is going to split up the 4.8A Max Output so charging may be slow if you’re charging 3 devices at once; but it probably won’t matter too much since you’re charging 3 devices at once. However, 3 devices charging at the same time is going to burn into the power capacity much faster too.

Input Charging:

There are 3 ways to recharge the power. You can either us built-in USB port and simply plug it into a USB wall charger, or you use one of the USB ports and use a Solar charger with it, and the power bank can recharge that way as well.

Lastly, you can recharge the power bank using the Micro-USB Input, which is found where the Built-In Micro-USB Cable is.

The recharge rate either through the Micro-USB Input, USB port, and Solar charging is done at 5V/2.1A. When recharging the power bank with the Micro-USB Input or USB Cable, you should use a 2 Amp wall charger or higher for a full recharge within 4-5 hours.


Size and Weight:

It’s not too large or heavy of a Rugged power bank, which isn’t a very common trait that Rugged power banks have.

It has a length of 4.5 inches, a width of 3.2 inches, and a thickness of 1 inch. The weight of the power bank is 8.8 Ounces, so it’s basically just half a pound. As a result, this power bank can be placed into a back pocket or you could hold it. It can also fit into a bag.

Functional Components:

The functional parts of this power banks are a bit everywhere.

Built-In Micro-USB Cable and Micro-USB Input

On one side is where you’ll find the Built-In Micro-USB Cable, and where the cable folds into the power bank is where you’ll find the Micro-USB Input port.

Built-USB Cable and USB Port

On the opposite side of that is where you’ll find the USB cable, and that USB cable plugs into the USB port when it’s folded into the power bank.

Solo USB Port

Then on the front side is where you’ll find the other USB port that is out in the open.

LED Lights and Buttons

On top of the power bank is where there are 5 LED lights that are used to check the power capacity of the power banks and to also be used as flashlights. The left button that has the battery sign and should be pressed to check the power capacity of the power bank. The button on the other side has a light bulb that is used to turn on the flashlight. The flashlight is quite bright, but not exactly bright enough for serious use.

Overall, everything is all over the power bank, but it’s all for a purpose. The USB ports aren’t together because the USB cables folds into one of the USB ports; as well as the Micro-USB cable being able to fold into Micro-USB Input port. It’s all done for the sake of increased portability. So even though the power bank does have two built-in cables, everything is concealed and still easy to access.

There is no power button since charging automatically starts when you plug a device into the power bank.


Structure and Material:

This is the strongest part of the power bank because it’s built to withstand shock if it were to drop. Also, it has an IPX6 waterproof rating and that means that when the built-in cables are folded into the power bank, then the Goal Zero Venture 30 power bank can withstand jets of water.

With that said, the main flaw with this power bank is that there’s still a USB port that isn’t covered; as a result, the power bank can very well get damaged if water were to go into that exposed USB port.


On the tech side, the power bank makes use of safety tech that is able to keep you and your devices safe during charging.


This power bank is for anyone that needs tough power banks that can survive against drops, as well as water. With that said, we can’t help but think that this power bank is going to be more reliable for those that own Android devices because the Goal Zero Venture 30 has a built-in Micro-USB cable that is going to be very useful for some that own an Android smartphone but not so much when it comes to an iPhone user.

However, the power bank still has 2 fast charging USB ports, and it doesn’t change the fact that there are 3 ways to recharge the power bank. When all of its traits are accumulated, this power bank is actually capable of a lot and is going to be useful for anyone that purchases it.



The power capacity has a pretty good conversion rate that is able to charge most smartphones multiple times over. It can charge 3 devices at once really good individual charging speeds of 2.4A and has a Max Output of 4.8A.


It’s a small Rugged power bank that keeps all of its components compact, and it’s not heavy. The functional parts are a bit over the place but it’s nothing serious because it’s all for the sake of keeping everything safe.


Even with the IPX6 waterproof rating, there’s still a single USB port that is open to water.


The Goal Venture power bank gives a pretty big plus to those that can make use of the built-in Micro-USB cable but that’s about it. It’s going to be very useful for anyone looking for a compact, tough and very capable power bank when it comes to power.

Specs of the Goal Zero Venture 30 Power Bank:

  • Capacity:            Advertised: 7,800mAh            Real Capacity: 5,500mAh
  • Output:   Per Port: 5V/2.4A      Max Output: 4.8 Amps

  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 4.5 x 3.2 x 1 inches
  • Weight: 8.8 Ounces


This Goal Zero Venture 30 power bank may not have a power capacity to last you 2 weeks of camping, but it does well enough with a power capacity to charge a smartphone a few times over. Along with the power capacity comes the ability to charge 3 devices at once and at pretty good speeds.

Best of all the power bank is shockproof and waterproof but to an extent.

Review: Coocheer 7,500mAh Rugged Power Bank

Power banks that are shock and waterproof are basically more helpful to use than power banks that aren’t. Since most of the time, we’re always worried about what will happen to our electronics when water gets on them or when they drop. Rugged power banks are able to absolve that worry since they can take withstand the harmful things that would normally effect, well, normal devices. Most think that these kinds of power banks are best used for when you’re taking a hike or going camping; however, they’re just as helpful for everyday use. Although they can be bigger and heavier.

This is the Cocheer 7,500mAh power bank that’s shock, water and dustproof. Let’s see how it fairs with its build and tech quality in detail, though.


Power Capacity:

The Coocher power banks use normal Lithium Ion batteries. So during charging it’s going to lose about the average amount of power capacity when the conversion of energy from the power bank to your device is happening. This is because there are inefficiencies that arise during charging that include the battery and the charging cable. As a result, the power bank does well enough to get about 5,250mAh of Output power capacity that you can actually use, so it does a 70% efficient transfer of power.

With a 5,250mAh amount of power that you can actually use, this power capacity is very useful to charge most smartphones because it can charge lots of smartphones about 2.5 times. To be honest, to get the best experience with this portable charger is best to use smartphones most of the time because you’ll get multiple uses from it before the charger is going to need recharging.

With that said, the Coocheer charger is actually still good to charge tablets like iPads but it’s important to know that they most likely won’t be able to charge to their full power capacities. The iPad Mini 4 will be able to charge to its full power by using the entire power capacity of the power bank and the iPad Mini 2 will get close at about 85% of power.

Charging full-Sized tablets will result in them charging to half their power.

Output Charging:

For a rugged power bank, we give the Cocheer charger credit because it has 2 charging ports and even though we don’t like the way that each of the charging ports has it’s own fixed charging speed, having the ability to charge 2 devices at once while your in the wild frontier can be very helpful.

5V/2.1A Charging Port:

This charging port is going to be the most helpful to charge any device at the fastest charging speed. So if you’re only charging a single device with this power bank, then use this charging port because it gives out the most power. With that said, this isn’t Quick Charge and this power bank doesn’t even feature Quick Charge tech so it won’t be able to charge your Quick Charge smartphones at their max charging speeds.

With that said, it’s going to do a pretty good job at delivering noticeable speeds and this is very helpful for when you want to charge tablets.

5V/1.0A Charing port:

This 1 Amp charging port should only be used when you’re charging 2 devices at once because it delivers a very slow charging speed. So when you are charging 2 devices at once, just know that whatever device that you do connect to this charging port will be charging slowly and that the 2.1 Amp port is going to be the most helpful port for faster charging.

Input Charging:

The recharging is slow because the power bank has a recharging rate of 5V/1.0A and as long as you’re using a 1 Amp wall charger or higher, it’s going to recharge to its full power within 6-7 hours.


Size and Weight:

The Coocheer power bank isn’t exactly large but it is bulky.

It has a length of 4.5 inches, a width of 2.6 inches and a thickness of 1 inch. The weight of the power bank is 9.3 ounces. So you can hold it in your hand but we find that the weight and the thickness make is uncomfortable to hold after a while. So it’s going to be best to just latch the charger onto your backpack, which is thankfully possible with this rugged power bank. Let’s go over the functional components.

Functional Components:

The charging ports can be found under a waterproof flap that covers them. Under the charging ports is where you’ll find the 2 USB charging Output ports and the Micro-USB Input port all packed together quite closely.

Out in the open is the flashlight that is found right next to the waterproof flap, the power button is on the long side of the charger and there are 4 Blue LED power capacity indicators on top of the power bank. You need to press the power button to begin charging, and the power button also turns on the flashlight when you hold the power button down.

At the top of the power bank is where there’s a Lanyard hole that is perfect to use a carabiner or rope on so you can connect the charger to your backpack and not have to hold it.


Structure and Material:

Of course, the main attractions of this power bank is just how well it’s built.

It’s a shockproof, waterproof and dustproof kind of power bank. This is because there’s a very thick rubber outer shell and also the center of the power bank is made of Aluminum, and as a result, if you drop the power bank and it won’t get damaged.

Also, it’s waterproof when you cover the charging ports with the charging flap. With that said, Coocheer doesn’t specify just how waterproof it. It can withstand water that gets on it or if water is splashed on it. However, the power bank cannot withstand immersion in water.


It makes use of the necessary safety technologies that make charging safe like Over-Charge, Short-Circuit, and Over-Current protection, as well as other safety technologies.


For the most part, we think that this CooCheer power bank is very reliable for those times when you’re deep in the wild and even those times when you’re not in the wild. We say that because it’s vital for our electronics to be safe and that can be done with this charger.

No matter if you drop it or get water on it, it’ll still function the same way and that is only starting to be the case with some smartphones these days. The other parts of the Coocheer power bank aren’t that great but the use of 2 charging ports is very helpful when you need to charge 2 devices at once.



The power capacity goes through a normal conversion rate, but it’s still able to provide lots of power to most smartphones to charge about 2 times or more. We like that the CooCheer rugged power bank makes use of 2 charging ports even though they each of have their own set charging speeds.


It’s actually quite small, but can be quite heavy. The main problem with its size is that it’s bulky. With that said, it’s very nice to use because it has a flashlight and it has a Lanyard Hole that you can use a Carabiner on and connect to your backpack.


The best part of the power bank is just how well it’s built because it can take falls and water too. However, it should not be immersed in water because that can cause damage.


Even though it’s larger and heavier than most normal power bank, we think that the Coocheer power bank can still reliable in a wild outdoor setting as much as a normal everyday one.

Specs of the Coocheer 7,500mAh Rugged Power Bank:

  • Capacity:            Advertised: 7,500mAh            Real Capacity: 5,250mAh
  • Output:   Port 1: 5V/2.1A      Port 2: 5V/1.0A

  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 4.5 x 2.6 x 1 inches
  • Weight: 9.3 Ounces


The Coocheer power bank does quite well in all of its areas, and even though it doesn’t go exceeding expectations, it meets them just at the line and that means a lot. The power capacity is enough to use a few times over, it has 2 charging ports, and the build quality can take whatever you throw at it.

Review: Innoo Tech 10,000mAh Solar Charger

Solar power banks are just your plain old power banks and the only difference is that they have a solar panel installed within them so you charge the power bank via solar panels. That’s really it. The thing that most people don’t understand is that a solar panel actually doesn’t charge that quickly with its solar recharging power, and you’re most likely going to be recharging it through the Micro-USB Input port that you use with most other portable chargers.

With that said, the solar charging isn’t the only valuable asset that Solar power banks take advantage of and they can be very useful in a lot of ways that more conventional chargers can’t be. This is the Innoo Tech solar charger, read on in this Charger Harbor Review to learn more about it.


Power Capacity:

Starting with the power capacity, it does pretty well. You’re started off with an initial power capacity of 10,000mAh and with conversion during charging that’s knocked down to about 8,000mAh. The solar power bank doesn’t take advantage of any special hardware like Pansonic battery cells or any other tech that is able to improve conversion during charging. With that said, we gotta say that the conversion rate is actually pretty good and this is mostly because of its charging speed having a max Output of only 2.1A.

With a power capacity of 8,000mAh, the power bank does a great job at being able to charge most smartphones 4 times or more. Although if you’re charging something like the Galaxy S7 and S7 Edge, then it’s going to fair a bit lower and being able to give about 2.5 full charges. As for tablets, this charger can do well but only if you’re charging a tablet alone. This is because power capacity won’t be split and all the power capacity will be focused only on a single device.

It doesn’t have the highest power capacity, but it will be able to last you for a few days, and we think that it’s a perfect amount of power capacity for hiking, camping or a simple outdoor venturing for either a few hours or days. So long as you’re charging devices that are within the portable charger’s capabilities of charging.

Output Charging: Max Output: 2.1 Amps    Per Port: 5V/1.0A

The charging speed could use some work. There is 2 Output charging ports and each of them is only capable of charging at 1 Amp. You’re not going to be getting very fast charging for most of the devices that you plan on charging. This goes for most smartphones and definitely for tablets like iPads that have a max charging rate of 2.4 Amps.

However, the charging speed is actually quite good in a way, when you’re charging a device alone. This is because charging speed is shared through the charging ports. So if you’re charging only a single device at any one time, then that device can potentially receive a max charging rate of 2.1 Amps. This is great for higher Amperage charging devices like tablets, and even for smartphones since they can charge beyond a 1 Amp rate as well.

So if you’re using both Output ports then charging speeds can be quite limiting as the power bank is splitting a source of power that is only 2.1 Amps.

Input Charging:    Solar Charging: 5.5V/250mAh      Micro-USB: 5V/1.0A

The main attraction for this power bank is the solar recharging aspect and as we said before at the beginning of this review is that recharging with solar isn’t anything special. The same stands here.

What we mean by that is that the recharging speed through the solar panel is the only 5.5V/250mA. So if you’re recharging it through ONLY the solar panels then it can take up to 40 hours for the power bank to fully recharge. Although that’s not really happening unless you’re constantly keeping it under solar rays. Also, Innoo Tech recommends that you do not leave it under sunlight for very long periods of time because it can actually overheat and get damaged. So if you think that you’re going to be able to recharge it as a respectable charging speed through solar power, then you’re wrong.

Then there’s the traditional way of recharging the power bank which is through a Micro-USB Input port. if you’re using the Micro-USB Input to recharge the solar power bank, then it will take about 6-7 hours to full recharge. It doesn’t matter what wall charger you use since the Input recharge is only 5V/1.0A.


Size and Weight

It’s quite a large power bank, Innoo Tech states that you can place it into your pocket and although that might slightly be possible, we don’t feel like it’s a comfortable possibility.

The length is 6.1 inches, it has a width of 3.1 inches and a 1.6 inch in thickness. It also has a heavy weight of 10.4 ounces. So now we hope you know what mean when we say that we simply don’t think it’s possible to comfortably place it into a pocket.

With that said, though we do think that it’s possible to either carry it around, but even then the weight of it can weigh you down. So it’s best to just use a carabiner on the latch that the power bank has and connect it to a back-pack. This way, you can hopefully get some recharge done if you’re walking outside on a sunny day.

Functional Components

Since the power bank has an IPX5 waterproof rating, the charging ports are covered by a flap and under the flap is where you can the 2 USB Output ports and the Micro-USB Input port. On the side of the charger is where you find the power button and on top is where there are 5 LED Power capacity indicators.

Charging automatically begins once you get a device to the charger and this leave the power button to either check the power capacity that’s left or to turn on the flashlight. Also, one bizarre thing we just mentioned is that there are 5 Power capacity indicators, and here’s why.

1st Indicator: Green: The charger is being charged by sunlight / Blue: 20% Power

2nd Indicator: Blue: 40% Power

3rd Indicator: Blue: 60% Power

4th Indicator: Blue: 80% Power

5th Indicator: Blue: 100% Power

This isn’t to say that solar charging stops when you reach a power capacity of 20%, it’s just that the LED light displays Blue when it reaches 20% of power capacity and Green when it’s recharging to 20%.

One portable side that we mentioned of how portable it is. There’s a latch on the bag where you can hook a carabiner and place it in a backpack. If you want to hold onto the power bank it does have some grooves and indentations that make it comfortable to hold.


Structure and Material

This can basically consider a rugged power bank and this mainly because it’s not only waterproof but also because the build is really solid. On the outside, it’s mostly made of plastic and has rubber in various places and this is mainly so that it withstand shock damage in the event of a fall. Another thing is that the siding that you see aren’t exactly parts of the charger because most or at least all the circuitry is in the center and safe from the environmental effects.

Then there’s the waterproof part. Okay, so the first thing you should know is that the power bank is only waterproof when you have the Output ports covered with the flap. When the charging ports are covered then it has an IPX5 water resistant rating. This means that it can withstand water jets in any directions, and it also means it can withstand rain. However, it CANNOT withstand immersion into water.


On the tech side, there’s nothing out of the ordinary as the power bank has the basic safety tech to keep you and your devices safe during charging. With that said, it can still overheat and get damaged if you leave it in the sun for too long. Also, don’t charge your devices while it’s being charged from the sun as that will increase heat.


For the most part, this solar power bank is reliable. With that said, it’s the solar part that makes it not so reliable for the main feature it was made for. We really think that charging electronic companies should come out with a solar power bank that is able to charge just as fast through its solar panels as it does with its Input ports. This is because recharging speed that is done through the solar panels is not very fast or realistic to even use because of how slow the charging speed is.

Another thing about this power bank is the Output charging speed. It does well if you’re only charging 1 device but if you’re charging 2 devices at once then the 2.1 Amps of power being split up isn’t going to provide a fast charging speed at all.



The power capacity is really the only impressive thing when it comes to its powering capabilities. The Max Output of only 2.1 Amps isn’t very versatile. The recharging that is done through the solar panel is VERY slow and most of the time you’ll find yourself using the Micro-USB Input port.


It’s quite a large power bank and a heavy one at that too. It’s fairly easy to use and can even use a carabiner with it so you can latch it onto a backpack.


The build quality is good if we’re talking about the structure and material with it being IPX5 water resistant and it can survive falls. Other than that, the tech side could use some improvements with faster charging.


It’s a reliable enough power bank that does well when you’re using it like just any other portable charger. When it comes to actually using the solar part of it, that when it is very unreliable.

Specs of the Innoo Tech 10,000mAh Solar Charger:

  • Capacity:            Advertised: 10,000mAh            Real Capacity: 8,000mAh
  • Output:  Max Output: 2.1 Amps    Per Port: 5V/1.0A

  • LED Power Indicators: 5 LED Power Capacity Indicators
  • Size: 6.1 x 3.1 x 1.6 inches
  • Weight: 10.4 ounces


Solar power banks, we feel, just aren’t there yet. Or at least this one isn’t. It does a pretty good job at being a base power bank, but when you consider what the solar part of it has to offer, it doesn’t deliver a strong package.

Review: FosPower PowerActive 10,200mAh Power Bank


Waterproof rugged power banks are one of the most reliable types of chargers because they’re basically reinforced power banks that still have the same capabilities just as any other one may have. With these type of portable chargers, there’s less care of whether or not it’ll get damaged from a fall, or water, simply because they’re built to better standards. The scenario that most commonly used is that you’d use these kinds of tough chargers while you’re camping but that shouldn’t always be the case.

This FosPower portable charger is a rugged power bank that can take on more things than just any charger, and it has some traits that not all other power banks use. Let’s take a look if you should use this tough charger in this Charger Harbor Review.


Power Capacity:

The power capacity initially sits at 10,200mAh and it mostly stays near that capacity for 2 main reasons. Reason 1 is that the power bank uses Panasonic battery cells and as a result, it has a better conversion rate. Another reason is that the FosPower power bank only uses a single Output charging port and this means there’s not a lot of current being outputted during charging, so not as much heat is being generated. With those 2 reasons, you can expect the power bank to lose about 1,500mAh or 2,000mAh of capacity during charging, although it mostly depends on how fast the device you’re charging is going at.

With its capacity, it’ll have no problem charging smartphones up to 3 times or more. Although smartphones with gigantic battery capacities like the Galaxy S7 Edge will do about 3 full charges. Tablets will only be able to take 1 charge or 1.5 charges because of their large battery capacities and because tablets charge faster which results in lower power capacity.

Samsung Galaxy S78,500mAh3,000mAh5,500mAh
Samsung Galaxy S7 Edge8,500mAh3,600mAh4,900mAh

Output Charging: 5V/2.1A


This is one of the strongest and strangest parts of the FosPower charger. It only has a single charging port. Other waterproof power banks like the RAVPower 10,050mAh and the EasyAcc rugged portable chargers have two charging ports but this one takes advantage of only 1.

Although this isn’t to say that it’s a bad thing. The single charging port is able to charge at 2.1 Amps and that kind of speed is pretty good for smartphones and for tablets. If you’re charging smartphones with this power bank then it’s most likely going to charge them at max speed, unless they’re Quick Charge compatible. Tablets will be able to charge near their max speeds because a max charge speed for most tablets like iPads is 2.4 Amps.

The use of a single Output charging port is something quite odd to see with a power bank that has a capacity of 10,200mAh because it’s the kind of capacity that you’d expect from a 2-port charging device. With that said, the use of a single port is actually quite efficient because there’s less heat being generated.

Input Charging: 5V/2.0A

The recharge rate of this FosPower is standard with it being 5V/2.0A and it can charge at that speed if you’re using a 2 Amp wall charger. If the power bank is charging at 2 Amps, then it’ll be fully recharged in 5.5 hours. If you’re using a 1 Amp wall charger, then it’s going to be fully recharged in 9 hours.

If you’re wondering what 2 Amp wall chargers are best to get, then we here at Charger Harbor recommend wall chargers like the Anker’s PowerPort 2 if you’re searching for something with few ports; but on the Higher port side, the Lumsing 5-Port wall charger should fair very well. Both of these of wall chargers will be able to recharge nearly every power bank you have at their fastest speeds.

Size and Weight

So the size of this rugged power bank isn’t actually too big. With its length being 3.9 inches, the width is 2.5 inches and the thickness is 1 inch. Also, the size is just moderately heavy with it weighing 7.7 ounces. Overall the size and weight won’t be able to stop you from carrying it in your hands and setting it down won’t really make much sense because this power bank is mostly meant to stay on you.

Functional Components

The functional components of the power banks are in the same general location, with most of them being under the waterproof flap.


What you find when you flip up the waterproof flap is the USB Output charging port, the Micro-USB Input port, and the flashlight. Outside of the flap, there’s the power button and LED light indicators under the power bank’s surface

Accessing the charging ports and the flashlight is obviously done by lifting up the waterproof flap but the cover can be difficult to lift up because it’s placed really solidly to prevent from any water and dust from coming inside. So you’re going to have to place a lot of force to access the charging ports but it’s a necessary struggle because it’s able to keep the power bank safe and serve its purpose as being rugged.

The power button does have a few important functionalities. The power button is used to check the power capacity, it turns on the power bank because the power bank doesn’t automatically begin charging and doubling tapping the power button turns on the flashlight. Double tapping the power button again turns off the flashlight. When there is nothing connected to the power bank, it automatically turns off. A little improvement would have been to allow the charger to automatically begin charging.


The LED power capacity indicators are good but they’re really bright. They’re actually so bright that you might even have to cover up the power capacity indicators because they can be an obstruction at times, like if you’re going hunting and want to be as stealthy as possible.

Portability, as we’ve already said, is really good with the portable charger being small and lightweight. There are grooves on the body of the charger that makes it easy to hold and there’s even a slot on top of the charger to put a compass and carabiner; this makes it so that you can latch the power bank onto pants or a backpack.


Of course, the build of the FosPower is much better than a standard power bank with its material being made from Polycarbonate and ABS material, the power bank is able to withstand shock damage from falls.

However, the most outstanding build feature is that the power bank is waterproof and dust-tight when you close the covering flap that goes ver the charging ports. Once the cover is closed, the Enclosure rating is IP-67, which means that it’s dust-tight and protected against water immersion for under 3 feet for 30 minutes long. So it’s important to know that taking it under 3 feet and for a longer amount of time may cause the power bank to be compromised to water.

Also, the charging port cover flap MUST be covered for it to be waterproof and dust-tight; lifting the cover case is going make the power bank easily open to water and dust damage.

On the inside, the there’s safety tech to keep the charging experience safe no matter what climate you’re in. Safety tech includes Short-Circuit protection, Over-Charge protection, and Over-Heat protection for those hot days.


We’re gonna say that it’s more reliable than just normal power banks. This is because of the Build quality.

With most portable chargers, there’s a lot of worry about dropping it or water damage, but that isn’t the case with this FosPower rugged charger since it’s built to withstand shock damage from falls, water, and dust. You don’t have to worry nearly as much about the elements and climate because the charger can last in temperature ranging from 32F to 114F. Overall, you’re more able to use this charger without being as delicate as other portable chargers you may have.

On the capacity and power side, it does well with just a single port to provide the most power and the charging speed is quite good at 2.1 Amps that’s able to charge most devices at or near their max speeds.

The portability is great with the dimensions being small and the weight being light. Best of all there’s a place to put a carabiner on the power bank and use it very closely on you.




The power capacity is quite good at 10,050 and it doesn’t go down too much because of there’s only 1 charging Output port. Also, it’s quite odd that there’s only 1 Output port because most power banks like these have 2 ports and you can charge 2 devices at once; in this case, though, since there’s only 1, there can be more power capacity to be focused on more devices.



Size and weight of the rugged power bank are actually really good with the charger being small enough to carry easily and you can even latch it onto your jeans or back-pack for very easy access. The cover that covers the charging ports can be difficult to lift up and the LED power capacity indicators lights are VERY bright.



The build quality is the strongest point of the power bank being waterproof and dust-tight when the cover is closed. Without the cover, the power bank is open to water and dust. It can withstand falls and shock damage that would leave normal chargers damaged.



We say that it’s actually more reliable than most power banks on the market because it can take a beating from water, dust, falls and climate weather. Not many chargers are able to do that unless they’re built to. This one is.

Specs of the FosPower PowerActive 10,200 mAh Power Bank:

  • Capacity:            Advertised: 10,200mAh             Real Capacity: 8,500mAh
  • Output:   Max Output: 5V/2.1A
  • Input: 5V/2.0A Via Micro-USB Input
  • LED Power Indicators: 4 LED Dotted Power Capacity
  • Size: 3.9 x 2.5 x 1 inches
  • Weight: 7.7 Ounces


Rugged power banks may very well be the future of power banks because of their build quality. Do you really want to have to worry about your power bank, the source of power for your device, getting damaged?

We didn’t think so. This charger may strangely not have 2 charging ports but it does well in its speed and capacity. The design is quite superb with its small size and lightweight. It also has a way to latch onto things like back-packs with a carabiner.

Review: RAVPower 10,050mAh Rugged Power Bank

Pic 1

You’re someone that wants to go all out, you’re not a careless person, rather you’re the type of person that wants to not worry about the little things in life. You’re carefree. Being carefree means that you know things will handle themselves because you’ve put trust into whatever you think will hold up.

It’s a great feeling to know things will be alright and when it comes to major things like out electronics, it’s quite difficult to be carefree because electronics are known to be fragile and break easily. It’s hard to be carefree when it comes to fragile electronics such as power banks.

Power banks, like our phones, are fragile. Dropping a normal power bank will most likely lead to it being damaged. Luckily there’s a solution and it’s the RAVPower Rugged power bank that allows you to be careless and carefree at the same time because it’s ready to take what’s thrown at it.


The power of the RAVPower Rugged power bank is an alright 10,050mAh capacity. This amount of power for a rugged power bank is good but it’s nothing to be in awe about; This is because power banks like these are usually meant to be taken on hiking or camping trips. This power bank can be taken anywhere but for it’s manufactured purpose of taking it to a place where there’s no way of charging a device other than the power bank, it’s quite lacking.

A power bank of its standard should be in the 15,000mAh range because when you’re in a place where there’s absolutely no place to charge your devices and far from civilization, having a higher capacity will ensure that you have enough power to last you for the circumstances ahead.

With that said, the power bank has a moderately high capacity at 10,050mAh which can charge most smartphones and tablets a few times.

 RAVPower RuggedPhone CapacityLeft Over Capacity for PowerCore+ Mini
iPhone SE10,050mAh1,624mAh8,426mAh
iPhone 610,050mAh1,810mAh8,240mAh

Samsung Galaxy S710,050mAh3,000mAh7,050mAh
Samsung Galaxy S7 Edge10,050mAh3,600mAh6,450mAh

The rugged power bank can perform well when charging many modern smartphones and if you’re using your smartphone heavily it can still last moderately long. The power bank has two ports so if you’re charging two devices at the same time, then you can expect the capacity of the power bank to deplete quickly.

The power bank can withstand many charges for smartphones but treading into devices that have more battery capacity and energy usage, you’ll start to notice that the capacity of the rugged power bank is actually underwhelming compared to smaller devices. It really depends on what you plan to charge the power bank with.

Smartphones? Yes, the power bank can handle a few charges.

Tablets? The power bank can do alright for about one charge only.

The design of this power is near perfect and it’s built for not only ruggedness but also for a great user experience. The size of the power bank is about the size of an iPhone 6, so you can hold it in one hand easily. The shaping of the power bank is done very well with a solid armor rectangular shape, the power bank is simple to handle.

There’s a hook spacing at top of the power bank so it can be hooked onto backpacks, like so:

Going into the functions of the power bank, it’s just as a solid experience as it is with the physical experience.

The power button is on the outside of the charger, then the rest of the functional areas are covered with a water sealed flap. Removing the flap reveals the two USB charging ports, the Micro USB recharging port, and the LED flashlight.

Output Charging: The output charging of the power bank is quite typical of what you’d expect with a two port charger. One USB charging port charges at 2.4A charging speed, which is great. The other USB charging port charges at a 1.0A charging speed, which means that it will charge slower than the other port. You’re going to have to choose which device you want charged faster, which is unfortunate because having two devices that charge at a 2.4A speed would be very convenient.

Input Charging: The input charging of the power bank is 2.0A charging speed. Faster than most recharging speeds, the power bank can be fully charged within about 3-4 hours.

LED power indicators are on the top of the power bank to show how much capacity is left within the power bank in increments of 25%.

The flashlight of the power bank is great if you’re in a dark setting but remember that using the flashlight will use the power of the power bank. Using the flashlight and charging a device will deplete the power bank of its capacity very quickly.

This rugged power bank is designed very well. Functions and usable physical features on the power bank are placed compactly so they’re simple to access and use; There’s no fumbling about where to find what on the power bank.


The build of the RAVPower rugged power bank is something to behold because that’s the main attraction of the device. Many electronic devices can’t withstand harsh conditions, the Samsung Galaxy S7 is one of the very new smartphones to be waterproof but it isn’t shockproof and still requires a case. Even though smartphones maybe not fortified to a point of being carefree, power banks are now able to be sturdy enough to handle harsh conditions.

Built for everyday purpose and beyond, the RAVPower sturdy power bank was built to take the damage that it’s dealt.

Shockproof: The outer casing the power bank is able to keep all the major parts of the power bank safe from moving and feeling the weight of a fall.

Waterproof: Rated at an IP66 Enclosure, the power bank can handle powerful water jets and other water related damage such as water splashes. However, the power bank cannot be immersed in water because it’s not rated at an IP67 Enclosure, where it would be able to withstand water immersion. Immersing the power bank into water for a very short period of time may not result in damage, however, for a long duration of immersion, the power bank will be compromised to water.

This is somewhat of a disappointment because the term “waterproof” can only go so far until it’s no longer waterproof as limits are reached.

Dustproof: The IP66 Enclosure makes the power bank dust tight.

The hard casing of the power bank is the best aspect of the device because it can take falls and slide across rough terrain. It may not be a fully waterproof power bank but the flap that covers the charging ports does a great job of not allowing water in.

It’s a well built purposeful power bank that welcomes falls and drizzles of water.


When you’re hoping for a power bank that’s going to last with your lifestyle, then your hopes will not be disappointed as long as you act with your hopes.

The ruggedness of the power bank as we stated before is the premiere aspect of the power bank. It can stay reliable through circumstances where other power banks cannot because it’s built for the damage.

However, in terms of power capacity, the power LED indicators must have their check ups because the usability of the power bank may be high and as a result, the power bank will need charging. You must charge the power bank when you don’t need it at certain times, otherwise, the reliability of the power bank won’t mean anything since it can’t even be used.

Having two ports and a flashlight can drain the power of the power bank quite quickly. Reliability with this power bank means:

  • You know the amount of energy you’re using from it
  • When it will be out of power
  • When you should recharge it

Along with a great structural integrity, the power bank comes loaded with tech that is able to make the reliability last as long as possible. With overcharging protection, Intelligent MCU control, and Voltage control, the power bank is able to last long because of all the control mechanisms within it to make sure that nothing goes wrong internally.


The capacity of the power bank is high enough that you can rely on it for main smartphones. Climbing into the device that have more energy demands, then the power capacity doesn’t seem to be that high anymore. It’s a great power bank to charge smartphones but there’s also another charging port to charge another device at the same time which can drain power capacity even faster.

It can be a great capacity power bank if your demands are minimal for a 10,050mAh capacity

The design for a sturdy power bank was bound to be great from the beginning of its creation because it’s meant to be compact and have all the functions of the power bank close by to make the structural fortitude work. Built with purpose, the power bank has a hook space for hooking it onto a backpack. The power button is on the outside.

All the functional aspect are under the sealed flap where you’ll find two USB charging ports, a Micro USB recharging port and a flashlight. Output charging is good with 2.4A for one port and 1.0A for another port. Recharging speed is great with 2.0A recharging speed, which is faster than most recharging rates.

The build quality of the RAVPower sturdy power bank is what it’s supposed to be and it’s somewhat of a disappointment. Being able to withstand shock damage from falls or sliding, the power bank excels.

Rated at an IP66 Enclosure, the power bank can handle dust and water that is shot at it with high pressure. This is good, the power bank can handle water being splashed onto it but it cannot be immersed in water. If it were immersed, the power bank would be compromised and lead to water damage.

Reliability is with the power bank and the user. The capacity of the power bank can differ its performance depending on how much you use it to charge devices if you use the flashlight and when you put it in charge.

A  fully charged one will have a far better reliability factor than a half charged power bank because the usage will make this power bank highly reliable or moderately reliable before all of the capacity is used.

As for the structural integrity, just don’t drop it into a body of water. It cannot handle going into water.

Specs of the RAVPower Rugged Power Bank:

  • Capacity: 10,050mAh
  • Output: 2.4A For One Port / 1.0A For the Other Port
  • Input: 2.0A via Micro USB Input
  • LED Power Indicators: Four-LED status system
  • Size: 4.6 x 2.8 x 0.9 inches
