It was too powerful for my vehicle and blew a fuse to cigarette lighter but worked great in husbands truck.

I have blown fuses right away and their customer service has been no help at all

I tried using the Cigarette Lighter adapter, but it blew a fuse

You'll definitely blow a fuse if you do that

Blew some fuses, but maybe my fault

fuses are still good, getting power, just does not turn on!!!

The one time I hooked up the cables reversed in the dark for a sec it blown all three 50amp blade fuses it has on the back side

so I put the cigarette lighter plug on and plugged it into the car, plugged in my electric drill and then blew the fuse on the cigarette lighter socket

Anyway, it has fuses designed to blow in that case

It will blow the fuses in your car without a doubt

See the video to understand about the replaceable fuse being permanently soldered in place.

Without anything plugged in, it immediately blew the fuse.

It blew the lighter plug fuse out

I love that it has the screw mount capability (one of the reasons I bought it, the other is the external fuses
