If you're playing Pokemon GO, then you definitely need to invest in a battery pack. While there are definitely ones that are cheaper than this model from Anker, this one is a bit different. You see, it supports Quick Charge 3.0. Which means you'll be able to fully charge your smartphone in just over an hour. That's a pretty big deal, and almost three times faster than traditional charging. Of course, not every smartphone has Quick Charge 3.0 (but the LG G5, HTC 10, Moto G4, Moto G4 Plus and a few others do). Luckily, Quick Charge 3.0 is backwards compatible with Quick Charge 2.0, Quick Charge 1.0 and even traditional charging. So you won't damage your smartphone by using this.
The PowerCore 10000 is a pretty small battery pack, even though it has a 10,000mAh capacity inside. It's definitely worth taking a look at, since it can fit in your pocket, and allowing you to play Pokemon GO even longer than before. Especially considering how fast Pokemon GO drains your battery these days. You can pick up the Anker PowerCore 10000 portable battery from the link down below, it's just $29.99, which is down from its regular price of $49.99. So definitely worth picking up, if you are in need of some extra power.
