ZERO BREEZE - Mark 3 AC

Single hose AC is garbage, never use that unless you really have no other better choice. Single hose system will leads negative air pressure and making the hot air from the outside get in to the interior from any gaps of the vehicle. Btw, zb mark 3 also have over 5,000 BTU, and it has dual hoses system.

Go with [this one](https://www.zerobreeze.com/products/zero-breeze-mark-3-ac), I'd say it strikes the best balance between portability and power, you won’t find a 5,200 BTU portable unit smaller or lighter than ZERO BREEZE. EcoFlow Wave 3 is another option, it's 6100 BTU, has higher cooling capacity, but much heavier and bigger than ZERO BREEZE, and not easy to be carried.

ZeroBreeze MkII for a 2-3 person tent and the MkIII for 4+ person tent. I’ve got the MkII and it’s just enough for a 4 person tent when below 95F

i use the zero breeze mark 3 hooked up to a jackery 2000. takes up a lot of space and kind of annoying to get the hoses set in place but the reward is not having to use the car engine, so its worth it for me. Very costly tho but im in in for the long term

I have a zero breeze and a roam vagabond rtt. One thing i dont think has been mentioned yet is the importance of insulation. My wife spent the extra $$ to get the insulating liner in the rtt. Obviously, it helps in cold weather, but without it, there would be no chance of achieving a comfortable cool temperature in there on really hot days. *With* it we have had to turn it down because we were getting cold in +95⁰ and very humid weather. Regarding power supply; i have the aux ZB battery bank and a jackery explorer 1000, and I *never* plan to have more than 6 hours of maximum ZB power. 2 adult bodies create a shit load of ambient heat, and the kWh math folks are referencing is at perfect charge and capacity; not what you're really going to have. When my family camps with me, I strongly consider biting the bullet and finding shore power. When it's just me: little to no issues staying cool. TL:DR Get insulation lol.

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.

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.

No. It isn't. These Zero Breeze units are an absolute joke. I have had three of them since the company was founded a few years ago (boats were on Hilton Head Island and Alameda, CA), and none have been able to keep a space larger than a head cool. They're expensive and impractical.
