i need help on a gadget that runs on a 12VAC output power adaptor.
what i want is to use this gadget on my car which is a 12VDC. i did not
try to hook it up directly to the 12VDC coz it may damage the gadget.
if you electronic experts there know some kind of a circuit that i can
make then pls post it or e mail it to me.
thanks and God Bless

hi,
I have looked at the websites about this seat, cannot find any technical data.
Can you read the ratings printed on the mains adaptor, example: 12Vac at XXamps. It might be easier to buy a 12Vdc mains invertor and plug the adaptor into that.
I have read some of the user reviews, some are not impressed with the massage feature, its just buzzes they say!.

hi,
Thats about 15VA [approx 15Watt]
I would suggest the easiest solution would be a 25W or 50Watt, 12Vdc to mains convertor, plugged into the cars cigar lighter socket and then plug the 12Vac adaptor into the invertor.
Do you follow that OK.
EDIT: this is the sort of invertor I mean, this one is much too big for your application, but you can get smaller versions.

Your expectations are quite unrealistic. It may turn out that the first thing your gadget does with the AC input is rectify and filter it to produce ceteris paribas 12VDC!
I guess there's a solenoid inside it, They use AC to magnetized/demagnetized an
object to produce vibration and not real motor, that's why they don't use DC.

For a Music Playing 5 motor massage seat I don't know what the solenoid would be doing. You're right the motors might be AC but the music player is certainly DC so there is a rectifier and a filter in there somewhere.
