Well a 300 watt inverter on a cigarette lighter outlet is a bad idea. The wire that typically goes to the cigarette lighter is not very heavy gauge. At 300 watts you will be pulling 25 amps!!! In my car, I have a 20 amp fuse on the cigarette circuit, and there are other things on that circuit too. What are you powering that needs so much power?
