Those of you living in colder environments (or if you simply like to ski or snowboard) might be interested in this gadget. It’s the “eneloop kairo” – a rechargeable hand warmer by Sanyo. The device comes with two temperature settings and an internal lithium battery which can be recharged 500 times. A PTC heater and microprocessor enables “high precision temperature control” while “preventing low-temperature burns.”  Move over gloves and pockets – we’ve got ourselves a hand warmer gadget!
