Pros

  • Very small size that can fit into your pocket and it's also really easy to hold.
  • Enough power capacity to charge smartphones multiple times
  • You can charge 2 devices at once, with one providing 2.1 Amps of power.
  • Recharge speed is fast with a 2.1A charging rate

Cons

  • If charging speeds were shared between the charging ports, it would provide more power to both devices being charged.
  • It's not as slim as Aukey would like you to think, so fitting it into your pocket can be uncomfortable

It’s quite well known that the higher the power capacity of a portable charger is, then the larger the size of the power bank will be.

Although, that kind of way of how portable chargers are structured isn’t becoming so prevalent because electronic companies are now able to fit larger capacities into smaller spaces.

This kind of innovation is changing how we purchase our portable chargers because now we don’t always have to consider the size of the charger to match the power capacity.

This is the Aukey 10,000mAh power bank and it packs quite a lot of power for its size.

Power Capacity

When you have a capacity of 10,000mAh in a small size such as this, then the Output capacity is bound to be much lower than the Initial power capacity.

.This is because the charger either uses multiple small-sized Lithium-Ion batteries or flat and slim Lithium Polymer batteries.

As a result, the conversion rate is going to be poor.

With that said, the conversion rate is also more dependent on whether or not you’re charging 2 devices at once and what the charging speed of the devices are. Overall, you can expect a 2,500mAh lower capacity than the initial power capacity and this will result in a 7,500mAh Output capacity.

Still, a 7,500mAh power capacity can still mean a lot if you’re charging smartphones because for smartphones you’ll be able to charge most 3 times over.

Ultimately, the power bank is meant to charge smartphones because of its relatively lower capacity.

For a tablet, we don’t recommend using this charger to charge tablets because you’re going to have to use the entire power capacity to charge a tablet to its full capacity.

Even then, a tablet uses more power and the chances of charging a tablet to its full capacity even if you’re charging it alone are slim. So it’s best to stick to lower battery capacity devices to make the power capacity more worthwhile.

Okay, so the charging speed of this 10,000mAh charger is good and it means well but ultimately power banks that don’t share Charging Current between their ports to reach their Max Output aren’t that good.

This is because the device that is connected to the 1 Amp port will almost always be charging slowly.

1 of the ports is able to Output 5V/2.1A, so you’d connect the devices like tablets or any device that you want to charge the fastest with this port.

The other port is able to charge at 5V/1.0A which is a slower charging speed. The max Output of the charger is 3.1A.

So you can take full advantage of both charging port’s speeds but ultimately, if you’re charging 2 devices, the 1 Amp port will always be limited to its 1 Amp because the 2.1A port doesn’t share its power.

It would be better if charging speed were shared. This way, if you’re charging two smartphones and both smartphones could charge at 1.5A, then they would be able to charge at 1.5A each. In this case, they can’t.

With that said, the power bank does try its best to provide a powerful charging experience with a Max Output of 3.1A, and we give it credit for that.

Input Charging: 5V/2.1A

Input charging is great because it’s 5V/2.1A. Most portable chargers its size just use a 2.0A Input speed or sometimes even lower.

So if you’re using a 2.1 Amp wall charger, then you can expect this power bank to be fully recharged within 5-6 hours. If you’re charging it with a 1 Amp wall charger then recharge time will double.

Size and Weight:

The most notable things about the power bank is its size. This is because the amount of powering capabilities that you’re able to get from this chargers doesn’t meet the size of it. That’s a good thing, though.

A Small Size with a High Power Capacity

Length is 3.5 inches, width is 3.1 inches and thickness is 0.9 inches. The weight of the power bank is 8.1 ounces. It’s a really small charger that can fit into either your front or back pocket, but at the same time, the charger is going to feel quite uncomfortable in a pocket.

We’re not saying that you shouldn’t put this power bank into your pocket but just because it can fit into your pocket doesn’t mean that it should go into your pocket.

However, holding it in your hand is the next best portable option because you can very well hold it, and use it if you’re charging a single device like your smartphone.

It’s a very portable charger, and definitely a new gen of chargers that is able to be small and still provide a lot of power. This is why we were really surprised by the size of the Aibocn 10,000mAh power bank for its large size. This charger is quite the opposite.

Functional Components:

With the charger being very compact, it’s really easy to find and use all the functional parts of the charger. Both of the USB Output charging ports are on the side, and there’s a flashlight between the USB ports.

The Micro-USB port is alone on another side of the charger. There’s a power button and 4 LED Power capacity indicators on top of the charger.

It’s really easy to use power bank, with charging automatically starting when you connect a device to the USB ports and the charging automatically stops if there aren’t any devices connected to the power bank.

The power button is mostly used to check the power capacity of the charger and turn on the flashlight by holding the power button down for about 10 seconds.

The Flashlight is LED but it’s not that bright and turning it on will obviously burn into the power capacity that’s available on it.

Build

Structure and Material:

This small charger is built very well just like many other power banks that are small. It’s separated into 3 pieces, there’s a centerpiece and 2 side panels.

The charger is made out of ABS Plastic, which is basically a stronger version of plastic.

With a structure that uses very few pieces and uses a higher grade of plastic, this charger can hold itself together very well and is actually on the edge of being a rugged charger if it had more reinforcement.

Even though it could take a few drops here and there, we don’t recommend dropping this charger on hard ground because the somewhat heavyweight can generate a lot of shock and inflict damage to the charger.

Tech:

Like many other portables chargers, this one offers safety tech like Over-Heating Protection, Over-Charge, and Short-Circuit protection.

Unfortunately, it doesn’t use any special charging tech like Quick Charge and it doesn’t use any special batteries like Panasonic battery cells.

Reliability

For a 10,000mAh power bank, this charger is very reliable.

The size is what makes it so reliable to use because you’re able to bring all of its powering capabilities and great build quality with you nearly anywhere you go.

So you’ll be able to have plenty of power capacity if you choose to place it into your pocket and when you take it out you can charge 2 devices wherever you are.

Charging speed could be more reliable with the charging ports being able to share their Amperage Current but alas that’s not the case like many other portables chargers.

Summary:

Power:

Output Capacity could better with the usage of better batteries and better management of heat but an average Output power capacity of 7,000mAh is still enough to charge smartphones a few times.

The charging speed means well, but if charging power were shared between the 2 charging ports then there would less of a compromise

Design:

The size is what it’s most known for and for good reason with it being able to provide powerful charging experience while still be able to fit into your pocket.

Build:

On a physical structure level, the power bank is really strong with few pieces being used and with it being made of ABS plastic. On the inside, things could be better to improve better conversion rate.

Reliability:

For the size, for what you’re able to get with this portable charger, it makes itself very reliable. There are very few other power banks that are this small and able to provide an initial power capacity of 10,000mAh and 2 charging ports.
