Refrigerator DC power consumption

[Miller0758]

Does anyone know off hand how much the refrigerator draws from the battery while running on gas? Our unit is in storage without access to AC and I was wondering how long I could run the refer while not connected. I was hoping to fire up the refer a couple of days before heading out so I don't need to pack a cooler until it cools down. Thanks, John

Roughly 2 amps per hour.

I know I can run my fridge for at least 4 days on gas/battery. Not sure how many days but so far 4 has been easy.


I have North Trail with Dometic 6 Cu Ft fridge.

2 days would do it and well, 4 days would do it even better ... Thank you

Might depend on what frig you have.

Dan, Unfortunately the rig is in SC and we're in NJ and the manuals are in the rig. It's the black one with the white interior ... Lol. I'll take a look at the nameplate when I get down there ... Just was hoping someone may have an idea.

You might think of a small solar panel to keep the battery system topped off. Be aware that your LP detector alarm is wired into the 12 volt battery system, and pulls a little power all the time the battery is connected.

That's a great idea Bill, thanks

We use a small 100 watt portable panel. It keeps the batteries topped off very well. We are able to stay 'off the grid' for 2 weeks. Granted we are frugal power users, but it does work very well for us.

120v AC amps X 10 = 12v DC amps.

4 amps AC @ 120v = 40 amps DC @ 12v

-just sayin

Just say your circuit boards and your LP alarm uses 1 amps at 12v. and you have a 100 amp hour battery. You can run your rig for 50 hours before you have used 50% of it capacity.

My LP alarm uses .1 amps, your circuit boards probably use .2 amps so lets say you are using .3 amps. and you have a 100 ah batt. 100 X 50% = 50 amp hours available without damaging your batts. 50 ah/.3 = 166 hours. you can add about 10% to that because the rate at which you are drawing is very small.

Using this, your battery will be dead in 300 hours or 12.5 days.
