I've had 3 power converters in the past. Two died because the internal fuses did not blow but the units did and one black and decker wouldn't put out enough power to keep my laptop running. This unit has been flawless and with the terminals instead of the cigarette lighter adapter I hard wired it to bypass the car key. It is small enough to sit at the ready tucked into my glove compartment. This is the best one for the job.

Digital display is useful. A bit touchy if your car battery is a little low. Mine was at 10.5 V.

It worked, but it kept beeping to tell me there was a problem.
