A basic, compact USB option is the Goal Zero Flip 20, which will charge your phone twice. We’ve relied on this to charge up phones on business trips and our GoPros on winter camping missions. It’s compact enough to fit in your pocket, with an easy-to-use flip-out USB charger. Testers loved the simple light display that tells you exactly how much juice is left in the battery. Goal Zero’s Flip line is worth checking out, though the 20 is definitely our preferred size.
