Peltier can cooler/heater

For those who want to keep their can drink cold even after being out of the fridge for a few hours have two options – an endless supply of ice cubes, or the Peltier thermoelectric device. While I still haven’t come across anyone who would want to keep a can drink hot for hours, I definitely know plenty of people who love to drink their Coke ice cold without any ice cubes. Powered by USB, you don’t have to worry about lugging around another power adapter during your travels. Just flick the switch between “C” and “H”, depending on how you want your drink/soup to be preserved.
