Nice one, Thanko. I’ve been thinking of buying a water heater for my room, but I’m afraid about the electric consumption. Now that Thanko has just released this USB Drink Cooler / Heater (P/N: HOTCOLG1), I only have to wait ’til local store here sell it and buy one. To use this device, simply plug it into your PC’s or laptop’s USB port (it supports both Windows and Mac), put the water or drink can on the reserved place, and turn it on by switching it to Hot or Cool temperature. Pretty easy, isn’t it?
