I absolutely love gadgets that charge via USB. I have sort of a “home base” where I write from, and there’s a powered USB hub where I can charge up my phone, iPod, whatever I need.
GREENHOUSE has a new device called the Eneplug. It’s basically a small standard duplex power to USB power adapter in a small form factor in “fun” colors. I have similar adapters and they’re good to have around.
You have your choice of green, orange, and pink or white, black, or yellow color combinations. A three pack runs $47.19, which sounds a bit high to us, but it might come down when they hit in a few weeks.
