Power your cell phone by hand

Hand-Crank USB Charger

How many times have you been stranded somewhere with a dead cell phone battery? I’m sure that it’s happened to everyone at least a few times, and it’s always at the most inconvenient time. There are many solutions out there to ensure that you’ll be able to get some extra juice to your phone, but here’s one that is a bit more eco-friendly.

Rather than relying on a single-use battery, or even one that needs plugged in between uses, the Hand-Crank USB Power Charger will give you some extra talk time with just a few turns of the handle. It will set you back $39.95 and will give you the necessary adapters for many different phones. It will also power many other USB devices. This might be worth throwing in your laptop bag, or even in your backpack when you go camping or hiking.
