It would be disingenous to call any 20,000mAh battery pack “small,” but Anker’s PowerCore Edge is at least thin. A mere centimeter thin, in fact.

Other than the unique design, this is the same PowerCore battery you know and love, so if you need some extra juice for your tablet on a long flight, or your phone during Pokémon Go outings, today’s $35 deal is an all-time low.
