Charge Your Gadgets with USB-Powered Powerstick

What could be better than that solar-powered device charger we mentioned a few days ago? In terms of sheer cleverness, I'll give the nod to the Powerstick. Plug this flash drive-like gizmo into a USB port, wait for its fuel gauge to read full (90 minutes brings it to 90% capacity), then toss it in your bag or pocket. Then, when your cell phone, Bluetooth headset, iPod, or other device needs power, connect the Powerstick and press its power button. Presto: instant power and charging.

The Powerstick comes with a carrying case and 9 power tips, thus assuring its compatibility with most mobile gadgets. (Click here for a complete compatibility list.) Interestingly, it sells for $69.95, the same price as the solar charger. I'd argue that it's more convenient to use than the latter, though obviously not quite as eco-friendly. [via Red Ferret]
