How long will fridge run on dc

How long does the battery last powing the fridge while driving. Was hoping to prepack fridge and run it off the battery for our trips.

The fridge will suck the battery dry in short order. just run it off propane when traveling. turn it off when fueling,

If the engine is running the battery get charged. If you just have a hourly lunch break you don't have to worry. The Fridge must be 3 way 110-Propane and 12 Volt

12 volt operation of a 3-way reefer must produce a lot of heat to cool the fridge. Maybe newer ones are more efficient that ones made in years past but the older older ones were known to not only discharge a trailer battery but also the tow vehicle battery as well. The alternator couldn't keep up with the amp draw of the fridge.

More likely the 16 xrb would just have the two way Fridge (110 and propane)

Ok so propane or frozen water bottles after precooling the fridge over night before the trip. The Wife thinks running propane while driving is kinda scary so I may just use the frozen water bottle trick. Farthest out we have planed is arou d 4 to 5 hours away from the house.

More do run on propane while traveling then don't. We've been doing it since 1977.

4 to 5 hours on the battery won't kill it I don't think. Also running on propane is done all the time, so I think your pretty safe.

I don't bother running the fridge in transit.


Precool the fridge for 2-3 days before your trips. Gas absorption needs more than overnight to settle in fully.


Make sure all of your stuff is already cooled down.


If need be shove a ice pack or two into the refrigerator side just before setting out.


The box is insulated enough where things will be OK for 4-5 hours as long as the door is not opened.


If you are doing an extended stop for lunch, then get the trailer as close to level as possible and run it on propane while stopped.


I'm rather paranoid about open propane cans while driving.
The battery charge feature of tow vehicles is small and only meant to keep the breakaway battery topped up.
As everyone else has mentioned, trying to run a fridge on 12V is a loosing proposition.
