Anker's PowerCore Slim lives up to its name with a slim, lightweight design that can easily fit into your pocket or nearly any bag or backpack. It's covered in an anti-slip silicon shield that you can rest assured won't scratch your phone, and it also helps keep the power bank protected too. There's a single USB-A port that offers a 2A output, and with its 5000mAh capacity, you can get up to two full charges out of it when powering up a phone like the iPhone 6s. Other, more powerful phones will obviously require more juice, so you'll want to keep that in mind when powering up.

With Anker's PowerIQ technology, this power bank offers an adaptive charge per device, so your phone or whatever's plugged in at the time will power up as efficiently as possible. A micro-USB cable is included with its purchase to keep the power bank charged up, though you'll want to make sure you have the proper charging cable to use with your phone. These short USB-C cables are a fantastic pick to use with your power bank, and there are short Lightning cables as well. Anker includes an 18-month warranty with the PowerCore Slim's purchase.
