Battery packs can be a wonderful accessory to have on hand, especially if you have a device which drains power quickly from the battery. This can be all the more of a real scenario with the recent launch of Pokémon GO, as users travel around their local areas with the phone screen on constantly while the phone draws down data and GPS location services so users can play. No matter what you're reasoning is for needing a battery pack, there are loads to choose from, but many of them, especially the ones with a high capacity, can cost quite a bit. For example, the Anker PowerCore Edge Ultra battery pack normally goes for $109.99. Right now though, you can pick up the battery pack for just $34.99 making this a steal for anyone who needs a larger capacity battery pack that is also high quality.
The Anker PowerCore Edge Ultra battery pack contains a capacity of 20,000 mAh, meaning it should be able to charge most smartphones at least 5 times. The battery pack features two USB ports so you could also charge two devices at once, and it has LED indicator lights to notify you of how much battery power is left. There is also a power button to turn on the battery pack, and a microUSB port for charging the pack itself. Devices also charges fast thanks to Anker's Power IQ technology.
