Refrige cooler

[Mrdi]

When an upright 43 quart cooler shows DC (4A/2.5A):
Does that mean when it is on it is drawing 4Amps from a 12 volt system and 2.5 from a 24 Volt system per hour?
At 4A it would delete the usable charge in a 12V,100 Amp Batt. to 50% in approx 12.5 hours of constant running time?
I imagine it cycles on and off?

The FP430 (43 QT cooler) may be powered via AC (0.75A) or DC (4A/2.5A) power and comes with cables for both.

Thanks

If you're talking about this one...

...I believe the two current ratings is for the two levels of cooling. If you're in a hurry to freeze something then it'll be the 4A draw. The 2.5A rating will be the other one.

It may be related to high and low mode, but generally dual voltage unit amperage shown like that in literature is indicating the different amp draw at each voltage. As basically power needed to operate in watts = volts x amps the higher voltage takes less amperage to the same work, but it appears this unit may be less efficient as voltage is higher or you get a bit more cooling at the higher voltage?

Mrdi, I think you had it right.

When running on 12v then the amp draw is 4amps. when on 24v then the draw is 2.5 amps.

I'm going by what I've read here.

So....
Which of the 40-50 quart size coolers seem to be effecient and
function well with no trouble?

Another Brand to look into is Engel. They're an austrailian co. that uses a special kind of compressor - it has only one moving part. What convinced me to shell out the extra $$ for the engel was the stories of people who owned the same engel for 30+ years in an off-road expedition vehicle. Mine is super efficient and quiet. I love it.

Waeco is another brand to check out. Perhaps the most efficient is Isotherm. Just do a search in google

Mrdi, Did you ever get the Fridge? If so how is it?

I've also found another comapany from AU called Evakool. They say they use Danfos compressors which are supposed to be efficient.

Does any one have any thoughts on them?

I figured I'd keep this question in a Fridge topic.

I have a Waeco CoolFreeze CF-40 Portable Fridge Freezer AC/DC running for 3 years continuous in my 2006. I have 3 pc1700 Odyssey (1 vehicle 2 under seat) wired directly together. If I drive 30 + min a day in the summer the fridge runs fine. If I drive less the fridge senses under voltage and shuts down to save the batts.In the winter no problem with the power. I run a 200A alternator. Always nice to have cold drinks at hand. :cheers:
