Thanko is striking while the iron is hot, or in this case, while the weather is freezing cold. After the warm mouse and mouse pad we saw some time ago, the weird gadget maker Thanko is now hawking a wrist AND a lunch warmer. The wristband connects to your computer via USB and reaches temperatures up to 40 degrees Celsius to keep your blood flowing during extra cold days. It has an extended Velcro strap so it fits a range of wrist thickness. The other new Thanko product for the winter is a lunchbox with built-in heater (pictured after the jump). Powered by a USB connection to a computer, the heater is made up of anodized aluminum that's supplemented with Styrofoam insulation so the heat doesn't escape while away from a power source like during commute.
