How efficient are power inverters that plug into the cigarette lighter?

August 17th, 2009

For example, take a small 100w power inverter that can charge/operate a laptop using the laptop’s normal power cable. How efficient is this, when compared to an actual car charger that’s intended for use in the cigarette lighter?

Thanks!

i NO LONGER HAVE A LIGHTER, IT FUSED OR SOMETHING WHEN i USED IT TO BOIL WATER FOR A CUP OF COFFEE IN THE MIDDLE OF THE nULLARBOR! Oops, sorry about the caps!
