Hey guys,

I got a electric mug recently. Best invention for a hot beverage drinker like myself. The only way to power the mug is with a car cigarette socket. My goal is to build a external battery pack with rechargable battery. I got a few RC car battery(NiMH) laying around for my disposal. The package saids 'Powered by DC 12V in car with cigarette socket adapter cable'. Could I just rewire the connecter of the battery to the mug connecter or do I need some kind of power regulator?

Thanks.

To add to what Chris said,

You might even consider a “wall wart”. Also, like Chris said, you need to know how much current the hot plate is expecting.
