Pokémon Go has taken the world by storm, but there's one issue plaguing us all and that's battery life. The game is notorious for draining your battery, even with the battery saving mode turned on, but there is a solution: a battery pack. We've teamed up with Tronsmart to give away 20 Presto battery packs to help power your Pokémon Go addiction.

The Tronsmart Presto is a 12000mA/h external battery charger with Qualcomm Quick Charge 3.0 that can recharge your iPhone or Android phone when you're out and about.
