Quite by chance a friend gave me a mini humidifier that runs off 12 volts - seems to use ultrasonics and starts working immediately upon appling power from a 12 volt adapter. It is designed for car use with the cig adapter included - great - 4 devices and 1 outlet. Wouldn't it be great to use for water vapor injection? It really shows the draft in my office floor area that always feels cold on chilly days like today. Built in 3 hour timer with auto shutoff.
