Portable 12 volt jumper and power supply

THere are a number of them that meet that. You can change out the battery with a gel-cell in all that I know of. Many have an AC inverter mounted on them. All I've seen allow you to charge from the cigar lighter socket all the time.

Jason,

Make sure that the jumper pack you purchase, has at least a 1000 amp peak boost.

I purchased a tiny booster from Home Depot. It started a completely discharged car with no problem. I paid about $50 for this small jumper pack. It could have started a couple other cars, after that. It was rated at 400 amps instant, and 1000 amps peak.

An average V8 starter might pull upto 250-300 amps, if it is old and tired.
