Not worth it, cheap construction, gets hot and caused issues with my laptop. It shut down during operation and now the power supply constantly buzzes. Although it turns on again, I just use the adapter plug with another power supply that I have. Money wasted.

Finally, it did not have a car plug but for a regular wall socket. The title is rather misleading. It burned out on the same day, but maybe my laptop is to blame since it was old and I just tried to find a charger for it to see if it works.
