Simple Start Batery Booster
 

I am thinking of carrying a BLACK AND DECKER SIMPLE START BATTERY BOOSTER in my vette.
The kind you plug into the cigerate lighter,wait 10 min. and start the car.

Anyone have any intelagence on these units-good, bad, any problem with the electronics,etc?
I carry a 350 amp Booster now but it is heavy compared to this small Black and Decker unit.
