I would take it to the technician. Sounds like you have an issue with the wire.

I once used a black and decker battery pack that plugged into the cigarette lighter that fed just enough juice to the car to light up the dash which then allowed me to get the electric trunk release to open. I picked up at the Target two blocks down street. But I think with all the new much slimmer battery packs on the market today the unit I have was discontinued.
I now have the Cobra Jump pack but I don't think I can jump start the car from the cigarette lighter anymore, it has to go right on the battery itself. Those cigarette lighter jump packs would be handy in this situation.
