ZERO BREEZE - Mark 2 AC

If you will be in a hotel I would not bother with a portable ac. These units need to exhaust hot air, so using them in an enclosed room would not be helpful for cooling. Lugging them around in the field as you are working would probably also not be practical. I’ve looked into both units you’ve mentioned for my camper, and for me the price was not worth it (based off reviews for Florida climate). In Florida, ac is not a luxury but a necessity. Any hotel in Florida will have ac (though some are not great or have temperature controls locked). Use a tower fan or box fan if the ac where you are staying isn’t up to par. If you are off grid, good luck because there is not much helping that heat without a real ac unit. The batteries on units you’ve mentioned are expensive and don’t even last the night if running full blast. If off grid, I’d just get one or two of the bigger 20v fans. You’ll be miserable either way.

Not the Zero Breeze it's terrible as is their customer service.

We have a conversion van so not even that much space and it was a huge waste of money. Tested on shore power. Company was impossible to reach and ended up contesting it with Amex and winning.

Zerobreeze with a power supply and solar panel like a jackery would be your best bet. That’s what I’m planning on camping with.

It’s the same BTU as my zero breeze, and the zero breeze is useless unless you have it directly pointed at you a couple feet away or less. I don’t imagine this would cool even a Prius? I could be way off but from my experience with my zero breeze it does not cool the vehicle or even a small area of it.
