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.

RAVPower Rugged 10,050mAh Power Bank

Power

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 S7 Edge	8,500mAh	3,600mAh	4,900mAh 2.3 Full Charges

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. That said, using a 1 Amp wall charger will result in a full recharge within 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.

Design

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 port but it’s a necessary struggle because it’s able to keep the power bank safe and serve its purpose as being rugged.

Using the Power Button

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.

Build

Structure and Material

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.

Can go Under Water

However, the most outstanding build feature is that the power bank is waterproof and dust-tight when you close the covering flap that goes over 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.

Tech

On the inside, 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.

Reliability

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.

All Rugged/Waterproof Power Bank Reviews

Summary:

Power

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.

Design

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.

Build

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.

Reliability

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.
