I bought a RME, and the one thing that I wish I had available was the rear 115V power outlet. I'm not big on buying car chargers for every single portable device I own, so it would be a great advantage to be able to use the standard chargers. Since this is a vehicle option, do they sell a Mopar kit? I cannot find a part number yet. The seemless integration would be worth it IMO, however, if I have to get creative I'll start looking into that.

Ahhh, Yea it's sure a nice feature to have. I charged my laptop last week with it. I've got an '08 Rocky Mountain Edition.....

Hmm... the RME we're buying has a 110V outlet too...

i bought a $40 inverter from sears with two grounded AC outlets that fits perfectly under the passenger seat

and how do they ground exactly?


the last time I looked there was a huge chunk of rubber at each corner of my commander, and unless rubber has changed it is a fairly good insulator/non conductor. ( there are subtle differences between the 2 terms).

unless you drive a grounding spike into the ground it cannot be earthed, the resistances are physically too high somewhere in the region of 2Mohm.

driving a spike and attaching a wire is Ok if stationary but when you're moving hmmmm there are a few issues

Let me get this right: Your argument is that there is nowhere with 0 Volt Potential on a car, so the only possible way to provide a ground would be grounding rod?

ground on a battery ( negative terminal) is actualy -6v the positive terminal on a battery is at +6v therefore as its a 2 wire DC circuit you have 12V DC.

if it was a three wire circuit then there would be a 0V line DC and AC are different beasts.

its not really a ground as such. we call ground over here earth and it confuses people too.


when the instructions say to ground it they mean to connect the ground of the unit to Ground ( earth) the unit will have a positive cable (RED) and a negative cable (black) to supply the raw 12V to it.

sorry if this is off subject a bit but does anyone know what can be run off the 110 outlet.
Last week our electricity went out, sub pump in the basement became a concern, I'm not sure what kind of power they draw and in the end it never became a problem.
But I started to wonder what could be run off the jeeps 110? anyone know?

A standard RME does not have the outlet, at least not when I purchased my '08 RME. However, if you get the popular equipment group, then its included among other things (remote start, heated seats...). I'd like to get a stock looking setup; if there isn't a Mopar kit, I'll start snooping around for a good location to mount and wire my own "kit."

ideally you will need a minimum of 600W rated and will need to mount it someplace cool air can get to it. in the rear qurterpanel is a good place and divert the 3rd row air con ducting . the cooler an inverter stays the better it runs ( and therefore also the longer it lasts) the 150W versions are dirt cheap over here and last maybe 12months as people don't think about what can be run from them. if you have a PSU rated at 75W then a 150w unit isn't going to cope for long , always go for the next size up.

I only read through the inverter part of the manual once for my wife's '08 Overland. As I recall it's a two-level inverter and I want to say the low setting is 150watts and the high setting is 350 watts. Either way, your sump pump is probably 1/3hp(?) and at 115 volts (output of the inverter), it's drawing 7.2 amps, or 828 watts. You would likely pop the inverter fuse if you plugged that in. I think Jeep has laptops and video games in mind.

thats about the size of it.

[timesublime]

1 Hp = 746W -> 1/3 hp = 746/3 = ~249W
P=I*V so I=P/v or 249w/115v=2.165A

Now this is while the motor is running, when the sump starts up it will draw more amperage.

[kmax]

Yes, in a perfect, frictionless world. Due to the inertial, frictional and efficiency losses from brushes, bearings, winding imperfections, etc., the real world load a 1hp, 115 volt AC motor will draw is 16 amps, or 1840 watts.

I'm not trying to hijack this thread, but I still believe plugging the sump pump into the Jeep's inverter outlet will cause the fuse to blow. Lets all try it and see!

thanks for the replies, on the pump question.
I was hoping for an already made solution for those who have a power outage, but guess not.
