The battery life of many mobile devices isn’t that great. I always find that my phone has died halfway through the day, but the Power Bank aims to fix that.
In the box, you get the power bank itself, 1 micro-USB cables, a wall adapter and a felt carrying pouch which is a nice addition as you can put all of your charging cables and the power bank in one place.
The unit itself is very compact and relatively small, it comes in either glossy white or glossy black. There are 4 blue LEDs on the front that show you how much charge is left. These also blink when you charge the power bank.
You can charge up to a devices at the same time thanks to the one USB ports on the base of the bank, there is also a micro-USB port in between to charge the power bank.
The power bank’s battery is 10400mAh, so it could easily charge an iPhone 5 at least 6 times in one full charge. The unit takes around 15 hours to charge fully and it can last a weekend away.
If you’re looking for a high-capacity backup battery for your tablet or smartphone then go with the FirstSingPower Power Bank. It has one USB ports, and it has a high-capacity so you won’t have to charge the unit that often. The only downside I found was that the Power Bank took a huge amount time to charge itself, but you can’t help that.
