looking for a dc to ac converter that will give me 550 watts at 4.5 amps. will be used in my tow vehicle and van to power my oxygen generator. Any help appreciated.
It might be better long term to get an O2 generator that runs directly off of 12 V DC. But as already mentioned, if you need anywhere close to 550 watts, it can't be just plugged into a cigarette lighter type of socket.
