USB Leg Wrap - Next Step in the Evolution of USB Heating

This USB-powered leg wrap from Thanko might be the most practical USB-powered heating device we've seen. Our Japanese is a little rusty – read: non-existent – but we're pretty sure from the pictures that unlike most USB heaters, which bind you to the nearest computer as you struggle to stay warm in the blistering chill of winter, Thanko's device has a converted that plugs into the nearest electrical outlet, making it far superior to this fuzzy, yet computer-bound device. It's not quite the portable, battery-powered wonder that we all might hope for (or is that just us? It seems like batteries would be logical extra power source for these types of gadgets), but at least you can take the leg wrap with you around the house – and away from the computer – when necessary.
