Duracell DPP-600HD Powerpack I keep it between the driver and passenger seats in my minivan

I keep it between the driver and passenger seats in my minivan. It worked well to jump start a vehicle from it to to the battery but not from just into the cigarette lighter/utility outlet. I use it as a charger without the need for car adapters and/or use to run a notebook computer for movies for my children while I drive. Big fat plugs might hit the power switch or limit the number of items you can plug in because of the outlet locations, but I am still happy I purchased this item.
