This is a 4 foot cable with cig-lighter plugs on each end which can be used to charge the booster pack in the vehicle.
It is nice to have an another way to charge.
Best cigarette lighter charger on the market.
I am sure that this cable works very well, but have not used it. I used the AC adapter to Cig-Plug to recharge this go round, which worked well.
I received it really fast and it worked great !
The products and service were very good.
Don't need another car battery and do it yourself and works excellent and carry it in your car or truck!!
You never have to open the hood of two cars again. Cigarette lighter to cigarette lighter and you're done!!!!
