Recharging a battery jump starter.

I am considering purchasing a jump starter for my car and I am interested in a model that I can plug into my cigarette lighter to start my car. I like this feature because I won't have to actually get out of my car to jump it. Also, how long does it take to charge a battery jump starter?
I would recommend purchasing a K&K jump starter that you connect directly to your battery under the hood. While, the cigarette lighter feature is convenient, I am not comfortable with pumping that much electricity through those thin wires on the back of the lighter. The jump starter manufacturers feel it is necessary to used 4 guage wire on the cables for a reason and your lighter doesn't have 4 gauge wire on it. The charge time depends on how many jumps you have done with it. If you have only jumped one dead battery, the charge time is around an hour. However, if you have done several dead batteries, your jump starter may take several hours to recharge.
