Review: Aukey 3,600mAh Portable Charger External Battery

pic-1

If you want a very portable solution to charging, then you’re going to have to use a small power bank. These types of portable chargers offer a charging experience that very few other power banks can. This is because once a power bank leaves the “Small” category of portables chargers, then the design and overall way that you can carry it just become the same whether it’s 10,000mAh or 20,000mAh. Although there are some exceptions like the Aukey 10,000mAh power bank with its small size.

This is the Aukey 3,600mAh power bank that is quite slim and very portable. Read on to know whether or not this small charger is really deserving of being considered portable and powerful as the rest.

Power

Power Capacity

Okay, so the power capacity is that of Anker’s PowerCore and Tylt’s chargers. It’s to be expected with its size and the initial capacity of this charger is 3,600mAh. Of course, there’s the conversion rate, and the Output capacity of this charger isn’t too bad with it only having one charging port and the speed of the port is 1.5A. As a result, you’ll be able to get 3,000mAh of Output power capacity.

Like many other portable chargers like this, the power capacity isn’t going to last days and is meant to charge a device to full only once and then this power bank needs to recharge. Unless you’re recharging an iPhone 5 which has a very low battery capacity, then the power bank may very well have some power left in it. However, for everything else, the charger is going to last for at least one charge for most smartphones and we think that the 3,600mAh Initial power capacity was trying to be able to charge a Galaxy S7 Edge with its 3,600mAh battery capacity but in this case, you’re at least going to get close to a full charge.

As for higher battery capacity devices to charge with this power bank; it isn’t the best idea, because if you’re charging something like a tablet with this power bank, then you’re only going to be able to charge Quarter of the way through.

(You would need 600mAh more power capacity)

Output Charging: 5V/1.5A

Charging for your devices is going to be quite good, as long as you’re charging small devices that have lower Amperage needs when it comes to charging. This means that charging smartphones with this power bank is going to provide the ideal charging experience because most smartphones have a max charging speed at 1.5 Amps. Other smartphones can even take higher Amperage speeds, like Quick Charge smartphones but this power bank doesn’t offer that. With that said, we think that Aukey really made it a point to provide enough charging power to smartphones and other small devices.

Just like the case with power capacity along with tablets, this power bank will not be able to charge tablets at their max charging speed, because a tablet’s max charging speed is usually 2.4 Amps.

Input charging:

So the Input charging could be higher with it at 5V/1.0A but it’s a recharge rate that’s acceptable with a power capacity as low as it has. It doesn’t really matter what wall charger you’re using since it’s going to recharge at 1 Amp and as a result, you can expect this power bank to be recharged within 2-3 hours. Even though the recharge rate is “Slow” for this power bank, it isn’t that slow because of its low capacity and you may be able to use on the same day you used it up.

Design

Size and Weight

This is a very portable charger with its small size and lightweight.

The length is 4.9 inches, the width is 1.8 inches and the thickness is 0.5 inches. So it’s about the size of smartphones as long as you’re not counting the thickness but even then for a power bank, it’s also very thin. The weight of charger is 2.9 ounces, so it’s a really light portable charger that you can easily place into your pocket because it’s small and doesn’t weight much. Holding it in your hand is also another option and probably the most used option that you’ll be using because this power bank can easily be held in a single hand while you’re using your smartphone.

However, fitting it into your pocket along with your smartphone isn’t the best experience because this power bank is still quite thick. So we can’t rank it as a Slim power bank but it’s nearly there.

Functional Components

There are only 3 functional components on this power bank and they’re all on the same side.

You can find the USB Output port, Lightning Input and LED power indicator all on the same side panel. So the first thing that needs to be stated is that this power bank doesn’t have a power button because the power bank automatically begins charging once a device is connected to it and turns off automatically when there are no devices connected to it. Even so, it’s really strange that this charger doesn’t have a power button to at least check power capacity when you’re not charging a device. It’s almost like Apple removing the Headphone jack on the iPhone 7. Such a basic feature is gone and even other power banks like the Lumina 15,000mAh has the same design.

Instead of using 4 LED power capacity indicators or even fewer than that, it uses only a single light to indicate the power capacity and the light changes colors.

0%-20% : Red
20%-60% : Green
60%-100% : White

Although this kind of system for reading power capacity is helpful, it isn’t nearly as helpful as having multiple lights for telling the power capacity.

Lastly, there’s the Lightning Input and it’s really strange to say that this power bank is recharged through a Lightning Input that uses a Lightning charging cable. So iPhone users can rejoice because they can recharge this power bank with their own charging cable or the one that’s included with this power bank.

pic-2

It’s still really strange because nearly every power bank on the market is recharged using a Micro-USB Input.

Build

Structure and Material

The power bank is made of plastic with a light varnish that makes it very easy to hold. The charger is separated into 3 pieces with a center piece and the 2 side panels, so it holds quite strong with the few pieces it has. Overall, the structure of the power bank is good but it isn’t anything special and we highly recommend not dropping it.

Tech

The tech of the power bank could be better. Sure, it takes advantage of safety tech like Current-Control, Over-Heating, and Over-Charging Protection. However, the main question to ask here is: “Does that all really work?”. This is because the power bank uses Lithium Polymer batteries and with that, during charging the power bank can heat up which can cause the batteries to expand. When that happens, the structure of the power bank can expand as well and this can end up breaking the charger.

We do like that power bank is slim but it’s slim at the price of it not performing optimally. Of course, the power bank is capable of doing that and damaging itself, but most models are able to perform accordingly.

pic-5

Reliability

It’s a reliable power bank if you know what you’re getting. You have to know what you’re purchasing a power bank that a low capacity and will be reliable for only a single charge and be able to charge a single device at any one time. Then again, this charger is also very portable and you can take it nearly anywhere you go.

If the build doesn’t hold up and the Lithium Polymer batteries aren’t performing well, then you’re not going to be getting a reliable experience. With that said, you can always depend on Aukey’s 24 Month Warranty to save you.

Summary:

Power:

power

The power capacity is rightly aligned with the portability of the power bank and the 3,000mAh Output power capacity is going to be able to offer a single charge to most smartphones, as it’s expected to. The Output charging speed is acceptable as it can charge most smartphones at their max charging speed and the Input charger is strange to have a Lightning as an Input but it’s actually really cool.

Design:

design

It’s a small power bank, but not yet slim or at least it’s not slim enough to place into your pocket along with the smartphone. But you can place it into your pocket alone or you can simply carry it because it’s really light.

Build:

build

The Structure and material don’t have any problems but it’s what’s on the inside that could use some work. The power bank uses Lithium Polymer batteries that can have problems with expanding when too much heat is generated, although this isn’t prevalent with each and every one of these it’s still possible that it can happen.

Reliability:

For the most part, this power bank is reliable with its power and design. If you get a poorly performing one with its safety tech, then it could prove otherwise. If that happens then take advantage of Aukey’s 24 Month Warranty.

Conclusion:

Small power banks are meant to be simple to use and not have much to them. That case is very true with this Aukey 3,600mAh power bank as it doesn’t even have a power button and only 3 functional parts on the same side. There’s nothing too special about it, other than all the awesome aspects of a small and thin charger.

Review: Anker PowerCore 5000 Slim Charger

 

We’ve reviewed other slim portable chargers in the past such as the Jackery Air 6 and the Viivant slim power bank. Both of which were great at doing what slim power banks do best, by being very portable providing and just enough powering capabilities to be useful. Now there’s this Anker PowerCore Slim 5000 portable charger that is another runner-up as a slim power bank. Slim chargers are a part of portable charging tech that is actually growing fast because people want to be able to use a charger that is super portable and easy to use. In most cases, slimness is defined as being very portable and having an easy going user experience.

Let’s see if this PowerCore Slim is really a slim power bank that is able to deliver a powerful charging experience while on the go.

Power

Power Capacity:

Like most slim power bank chargers, this one isn’t meant to provide an immense amount of power. The power capacity is 5,000mAh but the actual Output power capacity that you’ll actually receive will be 4,000mAh. It’s actually a pretty good conversion rate considering that other power banks of similar sizing have poorer conversion ratings with their capacities falling thousands of mAh below their original capacities. Even so, with the PowerCore Slim’s 4,000mAh, you can expect to charge many smartphones once or twice depending on what smartphone you have. If you plan on charging an iPhone 5, then you’re most likely going to get two full charges; but charge something like the Galaxy S7 Edge and you’re going to be left with 1 full charge and just a little bit more power to spare. For a tablet, we don’t really see the logic of charging something like an iPad with this power bank. If you do charge a tablet, you can expect it to charge halfway through. Overall, you can expect the usage of this power bank to last all of a single day or quite possibly for two days if you’re using it scarcely.

You’re not exactly purchasing this charger for its powering capabilities, instead, it’s the amazing portability. Which we’ll get to in the Design section.

Output  Charging – 5V/2.0A

pic-3

The output charging speed of the PowerCore Slim is quite fast, and we’re surprised because slim power banks are basically your cylindrical portable chargers but they’ve just been flattened out. The fast possible charging speed that you can get is 5V/2.0A and as a result, most smartphones will be able to charge at their max speed, as long as they’re not Quick Charge compatible smartphones (Quick Charge devices charge at their fastest rate with Quick Charge tech). This power bank does not use Quick Charge tech and will not charge your Quick Charge compatible devices accordingly. However, if you’re connecting any smartphone, it will charge as fast as it can at its standard rate. This goes for iPhones and Android smartphones. For tablets, the charging speed is close to the charging limit of tablets at 5V/2.4A. If you were to charge a tablet with this power bank, then it’d be faster than 1.0A Output; so you can expect charging near its max speed.

We’re really glad to see a relatively fast charging speed implemented with such a small power bank charger and we here at Charger Harbor really hope to see more slim devices use a faster-charging speed than 5V/1.0A; just like this PowerCore Slim has done.

Input Charging – 5V/2.0A

The Input charging is another aspect that surprised us. The usual case for small portable chargers is that they either have slow Output charging and slow Input charging, or they have Fast Output charging and Slow Input charging. That’s not the case here, instead, the Input speed is 5V/2.0A, which is the same as the Output charging speed. As a result, if you use a wall charger that has an Output of 5V/2.0A or higher, then this slim power bank will be able to charge to full in 3 hours. If you’re using a slower wall charger that has a charging rate of 5V/1.0A, then you can expect a full recharge in 5 hours.

We really recommend taking advantage of the 2 Amp recharging rate, because you may be able to use the charger again in a single day if it charges fast enough.

Design

The form factor is the main reason why this power bank is made. It’s a flat power bank that is easy to hold and place nearly anywhere to be as portable as possible. The slim charger is 5 inches long, 2.5 inches wide and 0.4 inches in thickness. It’s also lightweight at 4.2 ounces. Very similarly designed to a smartphone, this power bank feels like you’re holding onto a second smartphone because it’s able to fit into your pocket along with your smartphone, while your phone is being charged. That’s the beauty of this power bank, you can keep charging your phone while using it comfortably.

pic-1

It has a very ergonomic design that is great to simply hold in a single hand while holding your phone in the other hand. Or if you’re talking the on the phone, you can simply stack the slim power bank’s flat side against your smartphone; by doing so, it creates a very comfortable and seamless experience. Compare it to holding one of Anker’s mini power banks such as the PowerCore+ Mini. Sure the Mini is small but it isn’t designed in the way of being used right alongside your smartphone.

The covering the power bank is made of rubber, and this is another great feature because it provides grip to your hands and your phone. The bad thing is that the rubber covering can get smudges and stains quite quickly.

Also, since the slim charger is incredibly easy to hold and use, we recommend using a small charging cable because if you’re using a long charging cable, then it’s going to be an obstruction. By using a small cable, the power bank and your smartphone will be more in harmony during charging.

pic-4

All the functional parts are on a single side. There, you have the Micro-USB on the edge, the USB Charging port in the middle, then there are 3 White LED Power indicators and next to it is a power button. The power button is mainly used to check the power capacity of the power bank, because once you connect a device to the Slim 5000 it begins charging. If a device is not connected the charger, then it will automatically shut off. So overall, the power button is mainly to check the power capacity. The 3 LED power indicators are just enough to know how much power is left in the charger.

During the charging of your device, the LED power indicators blink depending on the capacity that’s left on the charger. When your device is fully recharged and not drawing a current, it will turn off. Also, when the power bank is done recharging, the LEDs turn off.

So the PowerCore Slim 5000 is what you’d expect from a slim portable charger. There are indeed other slim power banks like the Viivant Slim but the PowerCore does a great job at providing better design choices that make the user experience better in some ways.

Build

Small power banks tend to have a robust build quality because their compact size allows the materials and pieces to be centralized into one location. The PowerCore Slim is no different with its well put together body structure. Most of the power bank is enveloped in rubber and this is actually quite a good thing because it’s able to keep everything together and protected through the rubber layering. The limited functional parts is another plus since there are fewer pieces that can get damaged, this means the charger can be in more constant use.

As for Safety tech, Anker has not specified what safety tech they have implemented; the power bank does have certifications such as CE and RoHS and we think that there is indeed safety tech implemented with it. However, the power bank does tend to get warm if you’re charging a device that can take a high amount of Amperage.

Reliability

So, this power bank should not be relied upon for its power. Yes, we realize that power banks are made for the purpose of providing power but in this case, power is the second most important thing. It’s the design and portability that’s the most important. The PowerCore Slim’s design is flat and small, which is just like holding onto a smartphone. You can charge a smartphone while placing it in your pocket or talking on the phone with it an ergonomic design that is contoured to stack up against your smartphone very smoothly.

As for the powering strength, the power capacity is enough to charge a smartphone either once or twice. This is a daily kind of use portable charger, meaning that it can power devices up to a single day but you’re going to have to recharge it nearly every night.

Slim power bank chargers are paving the way for a better portable energy future. Normal cylindrical power banks are good but for a charger to be in the shape of our smartphone?!? The user experience can only get better.

 

It isn’t the most useful part of the power bank but it is the most used and we’re surprised by how good it is. It has an alright conversion with the real power capacity being 4,000mAh. It will last you either 1 day or a 2 days before needing to be recharged. The Output and Input speeds are both 5V/2.0A and this comes at a surprise but a welcoming surprise at that. Most smartphones will be able to charge at their max speeds and the power bank can be fully recharged in 3 hours if you’re using a 2 Amp wall charger.

 

The main attraction for the PowerCore Slim, with the keyword being “Slim”. The size and weight of a power bank, the charger can be placed in your pocket while it’s charging your smartphone or you can be talking on the phone with the power bank stacked against your phone. Its amazing ergonomic design and rubber covering is what makes it awesome to hold and the automatic charging and turning off capabilities are what make it awesome to use.

 

The build, like most small portable chargers, is quite good. the rubber encasing makes it solid. The slim charger can get warm if it’s charging a device in need of high amperage.

 

Of course, this charge is reliable in the way that it’s slim and portable. The power capacity is small but enough to last for a day and the charging speed is better than most small power banks.

Specs of the Anker PowerCore 5000 Slim:

  • Capacity:            Advertised: 5,000mAh             Real Capacity: 4,000mAh
  • Output:      5V2.0A
  • Input: 5V/2.0A via Micro USB Input
  • LED Power Indicators: 3 LED Power Capacity Indicators
  • Size: 5 x 2.5 x 0.4 inches
  • Weight: 4.2 ounces

Conclusion:

Slim portable chargers aren’t a new a kind of power bank category but they seem new because they’re just getting started on becoming known. This is a good thing though because they may very well be the future of portable chargers. This PowerCore Slim is a strong example of what a slim power bank is capable of at its apex. With its good Output power capacity, fast Output and Input charging and awesome design that makes it really easy to use. This slim charger has done an amazing job at being easy to use while still allowing the user to use their smartphone easily.

Review: Viivant Slim Portable Power Bank

 

Small slim power banks are a category of portable chargers that can be a very good alternative if you’re looking for a portable charger that isn’t just small but it’s also flat. If you’ve taken a read of our Jackery Air 6 Review, then you know what a slim power bank has to offer and why they’re so awesome to use. However, slim power banks are still just mini power banks that have been elongated.

Or are they?

This Viivant slim charger is actually very surprising with what it’s capable of and Charger Harbor is here to do a review on what this power bank is capable of. Read on to know why this flat charger may very well come on top in the best slim power bank category.

Power

Power Capacity:

As I said before, capacities of slim power banks are meant to be small because of their size and even though that’s the case with most slim power banks, it’s less prevalent here. The Viivant features a power capacity of 5,000mAh and it matches the capacity of Anker’s PowerCore Slim 5000 charger.

The Viivant actually does a good job with retaining its real power capacity and by that, we mean the power bank loses about 1,000mAh of power capacity and what you have left is about 4,000mAh of Output power capacity left to use. Considering its size, this kind of capacity is really good. This small power bank can charge nearly any smartphone to its full capacity. Some smartphones will leave the Viivant portable charger with more power capacity to spare in case you need to use it again. If you choose to, you can even charge a tablet with the charger but we recommend using the full 4,000mAh available capacity because tablets require a lot more power than smartphones. Overall, as long the Viivant power bank is fully charged, it’s going to deliver plenty of power for everyday use and it will most likely leave more capacity to use later on in the day.

Output Charging:

Moving onto the charging, the Viivant power bank has two charging Output ports. Yes, that’s right, this insanely slim and portable power bank has two charging output ports that allow you to charge two devices at the same time. One charging Output port has a charging speed of 5V/2.1A and the other Output port has a speed of 5V/1.0A. The logic here is that a tablet would be connected to the 2.1A port and smartphones would be connected to the 1.0A port; even though that logic is quite sound, the two ports should be used with smartphones. We say that because with two charging ports, the power capacity is being split apart.

If you want to charge a tablet with this power bank, then take advantage of this entire power capacity. However, if you charge two smartphones at the same time, then both of them will most likely charge to their full capacities. A smartphone that is connected to the 5V/2.1A port will charge faster than the 5V/1.0A charging port because of higher Amperage. It’s actually amazing to see a power bank of this size and capacity still be able to have two charging ports and for one of the charging ports to have 2.1A charging speed. The usual case is for a power bank to just have a single port with 1A charging, but this slim power bank exceeds expectations.

Input Charging (Recharging):

Recharging is done through a Micro-USB Input port that is able to recharge the power bank at 5V/2.0A. This is yet another amazing charging speed because slim power banks have slow recharging speeds but in this case, the recharge is rather fast. You can expect this power bank to be fully recharged if you’re using a wall charger that is capable of Outputting at 5V/2.0A or higher; this is because the output charging speed of the wall charger has to match the power bank’s input speed. Recharging the power bank at 2.0A charging will recharge it fully in about 3 hours and 30 minutes. If you’re using a wall charger that is rated at 5V/1.0A, then you can expect the power bank to be fully recharged within 4-5 hours.

Design

 

The main attraction of this power bank is the design. It measures 5.4 inches in length, 2.6 inches in width and 0.3 inches in thickness. Its got a weight of 5 ounces. Overall the portable charger is nearly the same size as your smartphone, or maybe even smaller than your smartphone depending on what smartphone you have. It can easily fit into your pocket along with your smartphone, you can hold it in your hand, place it on a surface to charge a device or put it in nearly any bag. The power bank is almost like owning a second smartphone, expect it’s just a source of power.

 

You can find the all the functional parts of the Viivant Slim in the same general area. The two charging Output ports and the Micro-USB Input port are on a narrow side of the power bank. There are 4 LED power indicators on the long side of it and a power button right next to the power indicators. The power bank automatically starts charging when a device is connected to it and it stops recharging once that device is fully charged. However, the power bank can be turned on if for some reason it stays off when a device is connected to it. Or you can even manually turn off the power bank when a device is connected to the charger. Ultimately, the charger can be very hands off and the power button can only be used to check the power capacity if that’s all you really want to do with the power button.

Other than the functional features that I mentioned above, there’s absolutely nothing else on the power bank and as a result, the charger is very smooth throughout its entire body.

The power bank is able to conduct Pass Through Charging but be please weary of using such a charging feature because if you read our write up on what is Pass Through Charging is, then you’ll know that it can cause quite a lot damage to a power bank.

The Viivant slim power bank is able to offer an amazingly slim design that can go anywhere and is capable of some awesome features.

 

Build

The entirety of the Viivant slim power bank is made of Aluminum. There’s a large center body and side caps that are both Aluminum. The side caps are placed very well and there are no signs of them parting ways from the main body. The center body harbors no opening or slits that may cause the body from cracking. The physical structure of the power bank is strong and holds tight.

Viivant hasn’t laid out any specifications pertaining to their safety tech but it can be quite clear on what they do have with this power bank. The slim power bank doesn’t heat up too much but there is still heat that can be felt while it charges. This is mostly because of the current passing through the device and into the device it’s charging. However, this heat generation leads to the Power problem that I mentioned earlier, which is the reduction of the power capacity. Viivant currently uses a Grade A Lithium Ion Polymer battery with this power bank and although Polymer does a good job at charging it does tend to lose a lot of capacity when charging is taking place.

The solution to this power capacity loss and to lessen the heat generation is to use Panasonic battery cells because this way, the power bank will have better conversion rate through its battery and less heat may be generated. Potable chargers that tend to use this are Jackery products like the Jackery Mini and Anker’s PowerCore 20100.

That might work, though. The Viivant slim power bank uses two charging ports, so it might be over-stepping its boundaries on what is should be capable of and what it’s actually capable of.

Reliability

It’s slim, it’s got the power capacity, the charging capabilities and the design of a smartphone. The Viivant slim power bank has plenty of flaws that can make it less than what it actually is; even so, the portable charger is still more capable than what’s expected of it. Most slim power banks of its size are expected to just a have a single charging port that has a charging speed of 5V/1.0A and the same Input speed. Not only that, similar power banks are expected to have lower capacities, even lower than the real capacity of 4,000mAh that this Viivant power bank has.

When you get this slim power bank, you’re relying on more than what’s expected. Sure the power capacity is less than what it’s supposed to be and it can generate quite a lot of heat but everything else is able to exceed expectations.

The Output power capacity of 4,000mAh can charge your smartphone about two times. There are two charging ports that allow you to charge two devices at the same time.

You can actually charge a tablet and a smartphone at the same time.

Two tablets at the same time.

Two smartphones at the same time,

I think you get the idea that this power bank is very versatile when it comes to charging. The sizing allows you to take it anywhere, after all, it’s a slim power bank and this means that you can easily fit it into your pocket along with your smartphone to have your smartphone charge while you’re doing something else.

You can depend on this Viivant portable charger for nearly all situations, along with its ability to exceed what’s expected from it.

power

The Viivant does nearly everything right, on the power side of things but the power capacity is missing a 1,000mAh of capacity. The power bank features two charging ports. One charging port charges at 5V/2.1A speed and the other charging port charges at 5V/1.0A  speed. The Input charging speed or better known as the recharge speed is 5V/2.0A and as a result, you can fully recharge the power bank in 3 hours.

design

Viivant has practically created a flawlessly designed slim power bank that does a great job at being super portable. It’s about the same time as your smartphone or maybe even smaller. All the functional portions of the power bank are few and out of the way. The charger can easily fit into your pocket along with your smartphone and is really lightweight at 5 ounces.

build

The build quality of the Viivant portable charger is nearly perfect when it comes to the physical structure of the power bank. However, Viivant hasn’t specified any safety tech, they promise that it has the necessary ones implemented. One main thing they should think about adding is a Panasonic battery because of its great conversion rate. They also need to work on heat generation, because the power bank can get quite hot.

reliability

When you use this power bank, you’re mostly relying on the things it ‘s done to surpass other slim power banks within its class. It does a great job of providing a lot of value within each category but the power capacity still needs to be perfected.

Specs of the Viivant Slim Portable Power Bank:

  • Capacity:            Advertised: 5,000mAh             Real Capacity: 4,000mAh
  • Output:      Port 1: 5V/2.1A      Port 2: 5V/1.0A
  • Input: 5V/2.0A via Micro USB Input
  • LED Power Indicators: 4 LED Power Indicators
  • Size: 0.31 x2.7 x 5.4 inches
  • Weight: 5.1 ounces

Conclusion:

The Viivant super slim power bank is wonderful with the way it goes about providing plenty of charging options and power capacity. It does have its fault with missing quite a big chunk of power but even so the power capacity is still enough to charge most smartphones two times fully. The size and dimensions of the portable charger make it so that it’s very portable in nearly any situation and can fit into your pocket very easily. It’s basically like owning a second smartphone. Overall, if you’re searching for a slim power bank to buy, this one is not something you should put aside. It goes further than most slim chargers.

Review: Jackery Air 6 Power Bank

 

Slim power banks are a highly preferable alternative to even the most capable of portable chargers that are bigger. This is because slim power banks offer a seamless experience because they’re about the size of your smartphone, lightweight and quite aesthetic. More so, they can be so portable that they can fit into your pocket along with your smartphone. Just like everything else, though, slim power banks have their drawbacks but are perfect portable chargers for someone looking for a slim and sublime experience.

This Jackery power bank called the Jackery Air is a slim power bank that does deliver on its slim promise but it doesn’t gloat too much about its other features.

Power

Power Capacity

Slim power banks generally have small capacities because they’re basically Mini power banks like the PowerCore+ Mini or the Tylt power bank. Really, the only difference is that slim portable chargers have a different design in that they are stretched out and are flat.

The Jackery Air features a 3,000mAh power capacity, but along with energy loss during charging you can expect the power bank’s real capacity to be about 2,500. We said that slim power banks are similar to cylindrical mini power banks, but in this case, the power of the Jackery Air is just a little disappointing. It does fit the criteria for what mini power bank’s capacity should be, which is at 3,000mAh but the energy loss puts the capacity of the power bank at an “Okay” level; however the cylindrical charger tends to have capacities within the 3,350 range and as result they’re more capable of having a higher output charging capacities. If the Jackery 6 Air had the same standard of capacity then it would be even more capable of charging a device.

Even so, this Mini power bank is meant to charge a single device and more specifically it’s mean to charge a smartphone; as tablets won’t be charged very much and along with its charging speed, it’s simply not a good idea to use this charger to charge a tablet because your experience will suffer. However, the power bank is capable of charging many smartphones to their full capacity or at least near their full capacity. Charging an iPhone 6 with a 1,810mAh capacity will prove quite well and charge the iPhone to its full potential. While charging something like a Galaxy S7 Edge will charge it about 3/4 of the way through.

Output Charging: 5V/1.0A

Charging speed of the portable charger is what you’d expect from such a small power bank with an output charging speed of 5V/1.0A. It’s a common charging speed and although we’re not surprised, we really want a push for faster-charging speeds to match the portability with small power banks, like the PowerCore 5000. You can expect the power bank to recharge the device you’re charging just fast enough for you to notice but not fast enough to exceed expectations.

Input Charging: 5V/2.0A

The recharging speed of the power bank is better than the power bank with an Input speed of 5V/2.0A and as a result, you can expect the portable charger to be fully charged within 3-4 hours. If possible, though, we’re sure the power bank would have held better quality if it were to trade charging speeds with the Input and Output.

Design

The most obvious aspect of the power bank is that it’s slim. The power bank’s length is 4.6 inches, a width of 2.4 inches and thickness of 0.3 inches. Overall its got the design the design of a smartphone and as a result, it can fit into your pocket very easily along with your smartphone if you don’t mind a little bit of tightness. Even better, the power bank is light with a weight of 3.4 ounces. One of the best design aspects other than the charger’s slimness is that it has no sharp edges; instead, the power bank is smoothly curved all throughout its body.

 

All the functional aspects of the power bank are on a single side. The functional parts are the Power button, the LED power indicator, USB charging output and the Micro-USB Input. It’s all well placed because the location of these things make putting the power bank into your pocket and usable very real. Although it was quite strange to see a power button on the corner of a charger.

The LED power indicator is a single light that simply changes color to let you know what capacity it’s at. Here are the colors that the power indicator shows and what the colors mean regarding capacity:

  • Blue = Full
  • Green = Near Full
  • Red = Near Empty
  • Blinking Red = Very Near Empty

It’s a simple power indication system that matches the power bank’s style and with its capacity, having multiple LED lights would have been unnecessary.

Overall, the Jackery Air power bank does a great job at doing what it does best and that’s being able to be very portable and most importantly being able to fit into a pocket.

 

Build

Smaller power banks tend to have a great build quality, because of their compact design and lightweight, they’re less susceptible to take damage since everything is less stretched out. This statement can be true for a power bank like the Jackery Air but only up to a certain point.

 

The Jackery Air 6 is made of an Aluminum casing and that’s really it. The portable charger doesn’t have any supporting structures that can allow the power bank to take and sustain damage and as a result, the power bank is very likely to get damaged and stop working. This kind of build quality is expected to happen with slim power banks because the main goal of the Jackery Air 6 is to be as a slim as possible and not be the best built.

Think of it as equivalent exchange; you’re able to get amazing portability but the power bank is structurally weak. Dropping this power bank is not something to be taken lightly if you still want it to be usable.

Safety tech for this power bank is apparently present, although Jackery doesn’t go into much detail about what the safety tech features. All they’re able to touch on is that the portable charger is able to have a safety protection circuit; Which probably means that it’s able to prevent a short circuit, so you shouldn’t expect safety tech features like temperature control or current control. Although with a power bank that only provides an output charging speed of 5V/1.0A, it doesn’t seem necessary to have the whole arsenal of safety tech.

Reliability

The Jackery Air 6 provides an optimal portable charging experience with its slimness and small dimensions, you can take this power bank nearly everywhere, no matter what situation because it’s basically like carrying a second smartphone. Putting it into your pocket is your best bet and putting it into a bag is a very simple thing to do.

However, the power bank’s reliability is cut short when you take into account the power capacity that’s going to charge your smartphone either 1 time or near full. It’s a perfect daily power bank that you can use at least once a day because, with an output capacity of about 2,500mAh, you can’t expect this charger to last for days; Not at all. However, if you’re living life on the go and want to be as lightweight as possible and still hold power with you then this power bank is ideal.

 

Power capacity for small power banks are suppose to be small but the Jackery Air 6 could have done a better job at providing a better internal capacity so that the output capacity (The capacity that you’re really getting) would be more worthwhile. Its charging speed is what you’d expect from a mini power bank with an output of 1 Amp and an Input of 2 Amps. You can actually use this power bank up in a single day and most likely use it again in the same day because of its fast recharge rate and small capacity.

 

The design of the power bank is what this charger is most known for. It’s slim and has small dimensions that make it like a smartphone. Putting it into your pocket along with your smartphone isn’t troublesome and it’s a lightweight power bank. All the functional aspect are on the side of the charger and its got quite a nifty power indicator that’s simple and useful.

 

The build quality of the Jackery Air 6 is “Okay” at best. The main thing about this portable charger is that it’s meant to be as portable and lightweight as possible and as a result build quality is much of a concern. Therefore this power bank has a rather weak structure and if you drop it you can’t expect it to work like normal. Although it does have an Aluminum case, its shock absorption ability isn’t there. The power bank doesn’t have much safety tech other than short circuit protection but it’s a simple charger with a slow charging speed so it’s not much of a concern.

 

Mini power banks are meant to be used on the go and they’re meant to be used up quickly. You can’t expect this power bank to last you for a few days or even the entire day because it’s only capable of charging most smartphones at least once to full capacity. However its portability is nearly second to none, and it’s most reliable when you use it like it was designed; such as putting it into your pocket to charge your smartphone. Even going on a run with this charger is easy because of its lightweight design.

Specs of the Jackery Air 6 Power Bank:

  • Capacity:                 Advertised Capacity: 3,000mAh        Real Capacity: 2,500mAh
  • Output:  5V/1.0A
  • Input: 5V/2.0A  Via Micro-USB
  • LED Power Indicators: Single LED Indicator with Color Variants
  • Size: 4.6 x 0.3 x 2.4 inches
  • Weight: 3.4 ounces
  • Comes with an Apple Lightning Cable

Conclusion:

The Jackery Air 6 is a great portable charger and it definitely shows what a mini power bank should be rather than just a cylindrical shape. Its flat shape is much more usable and portable because it’s nearly the same as carrying a smartphone. Powering capabilities of the Air 6 do fall short but when you take into account just how portable and easy to use the charger is, then you can take the power with more ease. If you’re searching for lightweight power bank that you can with you anywhere, then the Jackery Air 6 might be what you’re looking for.
