My power inverter will not power up my ps2 in my car but it will power up in a navigator anybody know why

 

I would check the voltage coming from your cigarette lighter, most inverters need right around 12-13 volts of electricity, and not all cig lighters put out 12 volts, if it isnt putting out that much you can tap into a constant (or switched) 12 volt wire and splice it to the existing wire and that should help you out a lot. It also wouldnt hurt to up the fuse size for the lighter.

 

i got it working now

 

What was wrong with it?
