jumper cables

I was looking in a catalog and found those jumper cables that just plug into the lighter socket. Has anyone used these, and do they work. According to the directions you just plug into both lighter sockets wait 5 minutes and start the vehicle. I think they would work as a back up set for me after putting new seats in and losing access to the battery compartment.

Don't even bother. To get sufficient charge into your battery to start will take ages, longer than most people are prepared to wait so the temptation is to try to start while still connected with the tiny little wires. This results in melted wires and blown fuses at best or a fire at worst.

Yup sounds like a gimmick to me! To crank most starters you need 100 to 200 amps, the cig lighter in most cars is limited to between 5 and 15 amps, it would take an hour or more to get any kind of charge that way.

True these 12v outlet starters are for trickle charging the reduced battery, not side of the road jump starting. Although I once jumped a Suburban from my Disco I once. Took about 5 to 10 minutes sitting there connected, then she fired right up.
Anything is possible, with the right tools...

Awful idea. But if you do get it, unplug the thing before trying to start the dead vehicle. I can't imagine trying to draw starter current through the wires running to the lighter socket. If you're lucky, the worst that will happen is that you'll blow a fuse. If unlucky, the wires get hot enough to degrade their insulation. 'not something I'd want to do to my vehicle, in the interests of reliability.

If for some reason you don't want to access the battery compartment for jumping, I'd suggest installing a heavy-duty connector in the engine compartment that the jumper cable can be connected to: http://www.warn.com/truck/accessorie...t_cables.shtml

No way you should be using the lighter socket for any serious amperage. I once had a compressor draw too much and burn the wiring - not a pretty sight waiting for a fire to catch!

Having the battery under the seat can be very inconvenient so run a heavy line to the engine bay and connect to that. You can even install a fuse box there for future use.
