[QUOTE="Geoff1946, post: 476713, member: 28452"] I have to agree the invertor is the main suspect, perhaps putting out some high voltage / high frequency waveform on top of the required "mains" voltage. One more point which struck me is that you said the low voltage blanket of the same power rating doesn't give the same warmth. It should do. The most likely reason for that is volt drop in the supply to it. I've sometimes found cigar lighter sockets which are useless above a couple of amps, either due to the socket/plug combination or to inadequate wiring in the car. If you could arrange to connect the blanket to the wiring that has been installed to supply the invertor you may find it works a whole lot better. Again an electrician with some test gear could possibly help you. [/QUOTE]
