Power inverter keeps blowing fuse
Recently I bought a Jenson 300 watt power inverter for my car so I could use my laptop. As soon as I plug it into the cigarette lighter, it blows a fuse that controls the cigarette lighter. I know the problem is with the inverter and not the car because I tried putting the inverter in a friends car and it blew his fuse also. Any suggestions on what could be wrong with this unit?

Does it blow the fuse even with nothing plugged into the inverter? Can you exchange it for another one and try that?

I have an invertor for my laptop in my pickup. My thoughts are the plug is shorting in the cigerette socket when plugging in. If the plug is not inserted crooked the crooked plug will short to frame blowing the fuse. Happened to me a couple of times. Make sure you wait till the invertor powers up before you plug in your 120 volt equipment. This will tell you if you have a shorted invertor or shorted cigarette plug. If the fuse holds until you plug in your 120 volt equipment then it blows you are pulling too many amps on your 120 volt equipment.

It is true that he is not going to be able o get 300W, but it is only going to draw that when it is loaded heavily. The fuse shouldn't be blowing. I agree, check for shorts, then take it back and try again. Could save a bit of cash and get a 200W unit, you don't want to (and can't) pull current for 300W without hardwiring to the battery anyway (through a fuse, of course.)
