1. Anker PowerCore+ Mini Portable Battery Charger
Even after constant improvement from the Niantic team, Pokémon GO remains a major power hog because of its constant connection to data and GPS networks. After having just one raid cut short by a dead battery, you’ll understand how essential a portable power bank really is. You don’t want to miss out on that Dragonite three blocks away.
The PowerCore+ Mini from Anker is an elegant solution to this problem. Despite being the smallest Anker power bank (about the size of a lipstick tube), its battery is large enough to fully charge most current-gen smartphones. Larger batteries are available for full-on binges, but the portability of the PowerCore+ Mini is all too useful for a mobile trainer.
