There’s no need to panic the next time your phone dies and there’s no outlet to be found. Built with 24,000 mAh of power storage, the Juiced External Battery Charger is one of the largest portable power banks on the market. This is enough to recharge an iPhone 6 more than 13 times over, which is quite a bit of juice. Featuring a 500 charge lifecycle, an included USB cord, two USB ports with a 2.1 amp output each, and the ability to charge two devices at once, you’ll never be cut off from the outside world again.
