Bests & Worsts Reviews from Amazon

There are five reasons why this external battery is the best option out there. 1) It is inexpensive. Compared to other high capacity batteries it is quite inexpensive. 2) It has the ideal capacity. It has a high enough capacity to charge almost any device at least once, and most phones can be charged multiple times. A larger battery is overkill for the majority of situations but this battery balances sizer and capacity. 3) It is slim, sleek, and comfortable to hold. It looks nice, it has a nice rubber surface on one side so that it won't slide away, and it is roughly the same size as most smartphones so it is easy to "sandwich" them together while charging, making it easy to hold. 4) Fast Charging. This is huge. I have a Samsung Galaxy S8, and this can fast charge it in no time. Not only that, the product itself can be fast charged as well, meaning less time it has to be out of commission while recharging. 5) It is made by Anker. I can not emphasize enough how great Anker's customer service is. They care so much about delivering quality products that work, and if you have any issues they won't hesitate to help make sure you get it figured out. I have had minor issues in the past with items being damaged and they are so fast to help out. Bottom line: Buy this. You absolutely won't regret it!Anker PowerCore II Slim 10000 Ultra Slim Power Bank, Upgraded PowerIQ 2.0 (up to 18W Output), Fast Charge for iPhone, Samsung Galaxy and More (Black)
