Switching 12 volt accessories to 110
I am trying to figure out if there is a way to take a 12 volt accessory such as a car radio and be able to plug it in to a standard 110 plug in the house. I don't know much about this, but i've seen a guy at the chevy dealership do it, so i know its possible somehow. Its just a crazy idea. Any help would be greatly appreciated. Thanks a lot and God bless.

You need to get a 120VAC to 12VDC power adaptor. Be sure it has the proper capacity to run your equipment.

All you need is a 12 volt DC power supply. It plugs into the 110v outlet and the supplies 12 volts DC to whatever you wish to power. I used to use one all the time on the test bench to power 12 volt DC stuff while I was working on it. Radio Shack would be happy to sell you one.

Technically, it's not an adapter - it's a converter. And, it's probably cheaper to buy one than to try to make one - and I know it's much safer.
Good luck!

There are any number of sources for 12v power, how long are you going to be running the 12v device?
A standard 12v power supply (ie radio shack).
A 12v power supply with a cig lighter type socket (also radio shack)
A 12v battery charger
A computer power supply (since you asked, unless it's a teenie 100watt job, would have plenty for your average head unit). The 12v line on my 350 watt unit is rated for 16 amps.
Whatever you end up using, just make sure it's a _regulated_ power supply. Radio shack sells some 12v units that are unregulated, and this isn't what you want.
FWIW, my Double DIN Pioneer has a stated maximum power draw of 10 amps, at maximum, this would exceed all but the most expense of standard 12v power supplies. You'd need a good battery charger/battery or PC power supply to get that much power cheaply.
