Power Outage - Jeep as Mini-Generator
 
Power got knocked out Saturday night here in NH. Still out now (Monday night!) - 52 deg inside at the moment, balmy compared with 49 deg this morning :) Could be a week before power is restored. :(

I work from home and my laptop and phone were dead, so I ran an extension cord from the Jeep inside to my home office, where its powering my laptop, and charging my phone! My wife's phone and a portable electric lantern are sitting in the Jeep now charging off USB & 12V adapter.

Nice mini-generator! :) - I have run the Jeep for a bit a few times today, just to be sure not draining too much, though these are all very light duty trickle charge devices.

So, what';s the trick to keep the Jeep Accessory mode powered for more than like 20-30 mins? Jeep keep shutting off power. I recall reading about a fuse pull/orientation that might accomplish this task.

Note: Jeep is not happy to provide power to run my Keurig machine - I tried, Jeep shut off power... Bummer. :)

My guess is it has a smart circuit to keep from running down the battery. It would use gas but for something that draws as much power as a coffee maker it would help to run the engine.

A generator would save you more money in gas lol.

Or you could use the Jeep to drive you and your family to a nice warm motel. I know rooms are hard to find. My friend in Springfield, MA does not expect power until Fri so all 5 of them and 2 dogs looked for a motel, but the MA and CT motels either had no power or were full, so they drove 90 miles west and are staying here in Albany.

Six years ago we put in a Kohler 12RES natural gas/LP generator and automatic transfer switch preceded by a 200A Intermatic house surge arrestor. If we have it for 20 years, that amortizes (forgetting present value, not much these days) to $450/yr. plus about $50/yr in maintenance (oil, filter, plugs, battery). We never go without juice, no matter the storm, which IMO makes it worth every penny especially mid-winter or in the dog days of summer.

Anybody know if the export WK2 comes with a 220V AC inverter?

No, we do not get any inverter options on our Oz spec units.

Could hook one up in the same place, shouldnt be too hard of a job, then the unit is hidden and will look standard.

except AUS plugs are a little bigger with a third earth pin.
And another approval and certification process for every vehicle.

I don't know that there is one. If you're drawing the max 150 watts from the inverter, that's pulling 13 amps from the battery. I haven't seen a rating for this battery, but if it's got 85 amp-hours (a generous number) then you'll drain it in seven hours.

You can move fuse M7 to a different position to make the 12V power outlet in the rear stay on all the time.

smart one :) I am in the same boat, this summer put generac 20kw standby with autoswitch and battery back up for 14sec of switching...


as far as jeep's inverter i don't recall exact spec, but i know it would not run my allienware laptop ( granted the power brick is like 250W)
