If I was asked to describe this device in a few words, they would be, powerful, reliable, flexible and long lasting. In one word – awesome! It’s an excellent power bank for traveling, especially if you have different devices and need them all charged. If it meets your needs, this power bank is an extremely helpful assistant.

Capacity & Charging Speed

Like the majority of the latest power banks, AUKEY external charger has a capacity of 20000mAh. With this level of capacity, the power bank is very efficient and can provide you with enough juice to quickly charge a device multiple times. Besides, it can charge four devices simultaneously through four output USB ports – there are three USB-A and one USB-C ports.

It holds energy for a long time. Basically, it feels like you use a wall outlet all the time rather than an external battery. After charging the power bank up to 100%, it’s possible to use it for several days before the indicator will go to one point. With only one point, it lasts for around three days, so it’s even easy to forget to recharge it. Seems like it should come with a warning saying ‘Don’t forget to recharge it!’.

When it comes to charging a device, AUKEY power bank is super fast and efficient. Here’s an example. When I needed to charge my phone from 80%, it charged it fast to 100%, and it stayed that way for a whole day. It’s worth mentioning that at that moment the battery itself was charged only up to 75%. A typical phone can be charged six to seven times with it.

Of course, depending on the device, the charging speed will vary since larger devices have higher capacity and require more power. However, you’d be able to charge a phone within an hour or spend a couple of hours if the device is running at the same time.

To fully recharge the power bank itself requires about eight hours. It may seem a bit long, but it makes sense for a battery of 20000mAh capacity. When fully charged, it lasts for several days, so it’s not a big problem to leave it charging overnight every now and then.

Look & Portability

The AUKEY power bank is slim and thin which makes it easy to fit into bags, medium-size purses or backpacks together with other devices. It’s a perfect option for travelers. Not only it lasts long and can keep the devices charged, but it’s also easy to pack and take with you on a trip. You can charge the device without taking it out of the bag. It’s a great alternative to the power banks that are designed thick or round. It can even fit in a man’s pocket.

However, if you are looking for something that you can use every day, fitting in a small pocket or purse, something that you can hold in your hand, it’s better to look for an alternative. While this power bank is easy to pack and use on the road, it’s not super portable without a well-sized bag. It’s quite long and wide, so it may not fit in a small purse or pocket. Its size is about the same as a 7” tablet or about 20% bigger than the iPhone plus-size models. Therefore, it’s essential to clearly understand what purposes it will be used for before buying this power pack. Again, for travelers, it’s a must-have.

Durability & Construction

As mentioned before, this AUKEY power pack is a bit long and wide also it may seem a little heavy. Its weight is 13.4 ounces, so it may add on some weight while being carried around every day.

One of the multiple advantages of this power pack is that it is compilable with a wide variety of devices. Since it has multiple USB ports (USB-A, USB-C, Micro-USB, and lightning), it can be used to charge Apple devices, including MacBook Pro and MacBook Air, Android devices, portable projectors, mobile entertaining systems, and even Nintendo switches.

The construction of the power bank seems durable. The surface has a matte layer preventing fingerprints on it. Also, there are LED indicator lights showing how much power the pack has. It comes with USB-A to USB-C cable in the set as well as a user manual.

For its price, it’s probably one of the best external batteries with the capacity of 20000mAh. It lasts for a long time, charges the devices quickly and can be an irreplaceable helper on the road. Bottom line, if it meets your needs, it’s a must-have power bank.
