    too much power for the fuse
    go buy some decent gyage cable and run a wire from the battery to another cig lighter and put a 16amp fuse on it

    if it blows a 16 amp fuse theres something really really wrong

    cheers

    My good buddy matt did the same on his Corolla but not only did he blow the fuse, somehow with a 165 watt inverter he managed to blow the entire dash. The fusebox melted i dunno how the hell he managed this. His stereo, clock , and various other dash componoents were out. Not good. he had to replace the entire fusebox. I guess it was that little fuse that didnt decide to blow.

    as a precaution, i recommend you stop cease and decist using your inverter on your cigarette lighter and do what pcman said.

    Cool

    Fuses are not precise components. Tolerance may be 800% either way. A 20A fuse may handle 35A for a few minutes before it blows.

    It's probably a good idea to run wires directly from the battery. Cig lighters are not really designed for this sort of thing.

    Yeah...fuses have severe tolerance issues. I had a 60 Amp fuse on my direct battery tap for my amps and I dead shorted it. It had time to melt the insulation off twleve gauge wire and almost start a fire in my trunk before it blew.

    If you do decide to run a wire from the battery, make SURE you fuse it somewhere near the battery

    If there happened to be a short on the wire running from the battery, it could cause a fire if it wasn't fused near the battery.

    Make sure you fuse both the positive AND negative leads to the battery, and fuse within first couple of feet away from the battery. The closer you fuse to the battery the better though you don't have to fuse within millimeters of the posts.
