It’s smaller than your palm and the key to connecting with, well, just about everyone. Meet JUICEBEE, a portable three-in-one charger that can power your device, even on the fly. As a wall charger, the universal piece of hardware adjusts to different voltages worldwide, and as a backup battery, it charges anything that works with a USB adapter (phones, tablets, games, headphones). And two ports — in and out — let you keep it charged while staying connected.
