You can never really go without juice for your various gadgets, as anyone who's ever been stuck out with a dead cellphone can attest. There's nothing quite like it to make you feel cut off from the world and maybe a bit panicky. Which is why this Universal Gadget Wrist Charger is pretty great.
Sure, it's not the coolest-looking thing in the world, but hey, it's useful. It's a little battery that lets you charge up anything that juices up via mini USB, such as cellphones, MP3 players or portable gaming systems. For $35, you get the wristband as well as a slew of adapters for common devices. Now you just need to figure out what to wear with it.
