Making a food warmer
« on: January 17, 2019, 09:44:40 AM »
Iím hoping someone here can help me with my problem. Iím looking for a battery operated food warmer but they do not exist, so I need to create one.  I work long hours on locomotives and love hot meals occasionally. Without electrical outlets I use a device called ďbarocookĒ to heat my food which uses a flame less heater thatís activated with water similar to an MRE. It works fantastic but each heating element is single use and costs $2. I also do not want to use an open flame such as a small camping stove. What Iím looking for is a way to supply power to one of the coffee mugs that heats up when plugged in to a vehicles cigarette lighter. Is there any kind of battery device and adaptor I can rig to heat food? Thanks

how big of a battery are you willing to lug around?

I'm not sure 100% if this fits the bill, but we have one of these and it's fantastic for heating leftovers on the road:

It also comes in a 12V version for a car cigarette lighter.
