Last year for Christmas my dad got a USB cup which keeps your coffee/tea warmer for longer, but this invention is taking it to the next level. A USB Powered Lunchbox made by Tanko.

The USB pouch easily connects to your desktop PC and warms anything up to a temperature of 60 degrees Celcius. It comes with an integrated heater to keep its contents warm. Sandwiches and other snacks will heat well, as will a full blown meal. Just make sure the plastic container that you store your food in is of a certain grade and quality, similar to the quality expected but a microwave.

I think this is an excellent idea. Plug it into your laptop or computer in enough time for lunch. I can see myself buying one in the near future.

The Hot LunchBox Pouch is safe to use and only costs 20 Dolars.
