Runbaken Cozycar Heater

Seen at a local swap meet, this little one inch diameter electric heater was intended to be installed in a sidecar to provide a bit of heat for the "lucky"passenger. The Runbaken Magneto company seems to have disappeared by 1932 but I doubt if the anemic charging systems of the day would put out enough to power this plus the lights. And 12 volts?
