An old computer power supply with 12 volt output.
Wonder if that would drive a CB mobile, or a CB
walkie? Makes me wonder if I could wire a lighter
socket to an old computer power supply and have a
couple amps of 12 volt DC?

I don't see why not. Twelve volts it twelve volts. I wouldn't think a CB
radio would require any super regulation and computer power supplies are
pretty clean.

Anyone know how much 12 volt DC a power supply provides?

They usually have a label on them giving their output. Here's an example

But, even a super cheap one should be plenty to run a CB radio.


Just remember, you need a resistive load on the 12 volt line before
you get ANY output on most supplies.

The 250 watt AT supply I have sitting on the bench puts out 11 amps
on the +12 side.
