ultrasonic mister

I am wondering if it is possible to operate a 24vdc mister on 12vdc?

Something simalar to this:

Item: MDC01; DC powered mist maker Transformer Input: AC110V; Output: DC24V UL. CUL. listed. Fogger size 1.5"(dia) x 1.25"(h), great for small shallow water container.

I've been doing a little reading on what it takes to run the piezo element and the oscillator circuits and I'm not very knowledgeable with circuits and I'm not sure if these will work on 12v.

Thanks in advance for any advise on this.

Probably not. Why do you want to run it from 12V anyway?

Cheers.

So I can run it off a 12V battery. I suppose I could pick up a DC/DC step-up, or just keep looking for a 12vdc mister, but most of them are

24V and 36V AC, and I'm not really up to wiring on up and getting one that works. It doesn't need to be like the one shown I would prefer one that I could build into a reservoir like the ones in a ultrasonic humidifier.

Make your self a simple voltage double circuit! That is, if you're up to it.

A complemary pair of Power Logic Fets being driven from some simple square wave oscillator like a 555 timer should do it, along with the proper diode and cap configuration of course.

I've done this before running low demand devices that were

24V dc, in the car.

I used the output as part of the gate driving voltage so the initial start up was a soft ramp to 24 volts but it made it easy to supply the needed voltage to the gates of the fets.

The last one I did used a small pic to monitor the current load in a battery charger for an HT that has a 12 volt battery pack in it.

A charge pump booster as the charger .. word out well actually.

You could run it off of two 12V batteries connected in series.
