Aukey's Quick Charge 2.0 power bank is currently on sale right now from Amazon, and this would make the perfect last minute gift for just about anyone on your list. This 10,000mAh capacity power bank is enough to recharge most phones about 3 times or more before needing a recharge itself. It also has Quick Charge 2.0, which allows you to charge your phone twice as fast, given that your phone supports Quick Charge 2.0. If it doesn't, don't worry because Quick Charge 2.0 is backwards compatible. So this battery pack will still power your phone at the normal rate without damaging the battery at all. Definitely a nice feature of Quick Charge 2.0.
This power bank features two USB ports, one which is colored orange does Quick Charge 2.0, the other does regular speed charging. It also includes a flashlight, which can be really handy in a power outage, which does happen from time to time. This power bank will also take a little over two hours to charge fully, a good idea to charge it at night, that way it's full by the time you leave in the morning.
