well not in the KJ but in my work truck I have a 1000W/2000W trip-lite
it is mounted under the rear seat of an F250
the distance required me to use 1-0 awg wire ,cut the ends off of some jumper cables
I can run any thing I want ,as long as the engine is on

I have a 500 watt mounted on the angled part between the outlet and the window on the passenger side. Been there for over 4 years and not one problem. Its close enough that if I need to run a laptop up front the cords will reach and handy to have at the rear gate. Worked great for the Christmas lights as well!:D

wow guess im the first pic in here. Now theres 2 ways to power these. 1 is hardwire to battery with either wireing/alligator clips or you can use a cigarette lighter. If you use a cigarette lighter it will not be as powerfull and will not run near as much. But for some reason the rear cigarette lighter in the kj holds much more power. I have no troubel using the rear one. but because i have subs i am probably going to wire into that power wire so i get full power. 400 watts for me camping is just fine.

Instead of permanently installing, I have a portable 4 in one unit that connects to the rear 12v. accessory plug for charging.
It is a 400watt inverter,jumper cables and tire air compressor.http://www.canadiantire.ca/AST/browse/4/Auto/SolarPortablePower/PowerPacks/PRD~0111810P/Motomaster%2BEliminator%2B600A%2BPowerBox.jsp

I have something similar to this - a standalone/portable. Got it at Costco, it's called the "Powerdome" - 500W inverter. Has it's own sealed battery, which I charge up at home before a trip. Has onboard Air Compressor, Jumper Cables, and a worklight.

Weighs about 10-15 lbs, and is about the size of your average car battery - with a nice sturdy handle.

I don't know which direction I am going to take. :confused:
I have one of those portable charger/air compressor/jumper but I don't like lugging it around.

what do you want to power?
that will play a huge roll in what you do

I had a 3 gallon air compressor I was going to mount in the rear of the jeep, and it was a 110v plug in. I've decided not to mount it but I still want an inverter, just not sure how big and powerful I need. I've never really had a large need for one, but one would be nice to have.

those thing pull lots of current
look at it like this W = V * A
so if a device is rated for 1 amp at 120V then that is 120W
now A = V / W
so 1 amp at 120V = 120W
120W at 12V = 10 amps

Those small compressors pull over 5 amps at 120V
so over 600W and take 150% to start them
so for a 5 amp compressor you will need at least a 600/900 inverter
but 5 amps at 120V is 50 amps at 12V
in other words you are going to be running some HUGE cables to the back of the Jeep

Which is why I am rethinking the whole thing. Not sure I want to go that route and get that far into it.

close enough for passenger to use (i find that passengers use it most) but high up enough to avoid snow/water. thought i'd join twack since he seemed lonely having the only picture :p

If watts = volts times amps (P=IE)
then
amps = watts over volts (I=P/E)

Your math was right, but the formula was backwards ;)

What gauge wire did you use? I just installed my 700w in that same spot...thanks for the idea. Now I just need to connect it

I have a 400W inverter beneath the passenger's side seat wired to the battery with 14 gauge wire. Not positive what value of fuse that I used. It's for my laptop.

Also I have a 1,500W inverter that I jumper directly to the battery with the engine running for the heavier appliances (coffee maker).
