Jim as Canadian Tire is blowing them out on sale its a good bet there will not be any to buy later in the year. Looking at the manufactures website they dont seem to be making them any longer - or at least I cant find one with the propane option. Not to mention that most of the Canadian Tire stores only stock one or two of this model at the best of times (some dont even have them at all) due to the many other cheaper more popular option/style ones they do carry made by the same manufacture. So if you really want one you might ask someone in Canada who is going to the rally to pick you up one sooner rather than later. Like today!

The capacity in US speak is: 10.567 US Gallons. Sizes is 20.47" x 20.08" X 17.7"

That appears to be the reason for electric-only absorption-type refrigerators in some European hotel rooms - no noise.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

Thanks for the tip

Thanks to Roy for the tip. We went to CT and picked one up today. I thought it would also be great to use while on long driving trips.

I thought this way also. If anything, it'll work in the vehicle just for road trips.
What I'm wondering though is if it's better to install an inverter in my vehicle so it will run off AC power and I'll be able to control the temperature. (there is no control of the temp when the cooler is on DC power)

You will waste battery power converting 12v to 1120v and then back to 12v. The 12v operation should be fine.

It would be less efficient, but if the thermostat is important to you, it is doable. It might even cool better on AC if it is like some camper refrigerators which use a higher wattage electrical element on AC.

In any case, don't run it when the engine is not running.

I picked one up and tested it, 12 volt works, 120 volt works way better, I would guess an inverter would be the way to go, although don't have an inverter to try.

20°C temperature difference would be a 36°F.

We had one of these types of coolers when we used a tent trailer many years ago. It worked quite good, but you had to watch the settings. When it cooled off good at night things could freeze easily, but if it was smokin' hot outside, it struggled to keep things cool at max setting. Still, all in all a better thing to have than a regular cooler if you have no fridge in your trailer.

We've tested it out on both 120 and 12 V, so far so good.

Given that it is in essence a 3 way adsorption fridge. I'm surprised that someone has not thought of buying one just for the guts to replace a dead fridge in their trailer. Even the rebuilt components cost more.

Does anyone know what the power draw is when the unit's run off a/c? I don't see it in the specs at the O.P.'s link...

I ask since it sounds as if you're thinking of one of those cigarette-lighter-plug inverters and many don't put out enough a/c to run a heat-producer like an absorption fridge.

Thanks for the specs, Roy!

Correct my math if I'm wrong, but isn't .7 amps a/c about 900 watts?

Bearing in mind we're talking about 110v operation while this unit's in the car:

Wouldn't a 900 watt draw require a pretty stout inverter, not to mention an interior car connection that would power it without blowing the connection's fuse?

Close to 7 amps @ 12v- pretty high draw on your battery, doesn't leave much else. Engel advertises one for less than 3 amp @12v, course it costs twice as much!!

O.K., Jim:

Which one of us is blind?

I'm reading the amps draw on a/c as .7 (point seven), or seven tenths of one amp.
