Charging device that requires 100-240 volts ac to produce 29 5 volts dc 1500 ma can you use a 12volt dc inverter to make this work?

Answer 1

It should work just fine,

first you jack up your car voltage to 120 AC,

and then drop it to 29.5 volts DC

Except for losses, it should be draining about 44 watts,

or about 3 and 2/3 amps from your battery
