Am I correct in saying the fridge will only work on 12V if the van is connected to the towing car?

How do I power the fridge if off-grid, other than by gas?

It’s gas only off grid Malcolm.
Even when connected to the car the 12v only maintains temperature. It has very limited cooling power.
The gas cooling is actually very effective.

What is gas consumption like when running the fridge 24x7 plus 10L water boiler plus cooking/making coffee on the burners? We are off grid for May bank holiday and I'm wondering if I'll need two 6kg bottles of propane (currently have one which is ~90% full). We're hoping we won't need the heater, the water boiler will be used sparingly, if at all, and the fridge will be run at 'cool box' temperature.

A typical fridge will consume at least 80 watts. That's nearly 7 amps at 12 volts. That means that if you have a 100 amp hour battery, you could flatten it in about 14 hours continuous running. Even with a solar panel providing daytime backup, you would be having night time problems which might ruin your battery. As Frantone said, it's a no-no.

Thanks for the confirmation.

Thank you Randa. Very happy to read your response. I had absolutely no idea, having got through 904's like nobody's business when we were tenting in the past. Cold gin and tonics will be flowing in the New Forest after all.

We used 907's in our campervan. A quick Google says that Towsure sell empty cylinders for £12.00 and Go Outdoors will swap it for a refill at £35, which seems an awful lot. 2.72kg of gas at £35 is £12.87 per kg.

The list price for a refill of a Calor 6kg cylinder is £21.85 or £3.64 per kg.

I was so impressed with the little fridge. It gets really cold very quickly and we have lots of ice.

I agree that if you don't use much gas anyway the cost per kg isn't a cause for concern and we've had our current 6kg cylinder for about 3 years and it's still only half empty/full. We only use it for the cooking hobs and that's it. But if you regularly use pitches without hook up and have a gas boiler as well as heating in cool weather you can go through them quite quickly and as well as swapping more often, with a 907 you're paying an awful lot more, whether it's cleaner burning with a higher calorific value or not.
