Hey everyone,

I'm having a bit of a tough time. I'm trying to find self heating coffee mugs or thermoses. The only ones I've found heat with car chargers, and I need this thing to heat itself so that I can take regular water, heat it up, and add my instant coffee.

The only problem is that so far, as I mentioned, all I've found are ones that use car chargers or the Wolfgang Puck one that was recalled because they were exploding on people.

So basically, does anyone know of mugs that can self heat water? Thanks for the help.
