ZERO BREEZE - Mark 2 AC

I really like my zero breeze 2. I’m in Texas as well, I get it man. It sucks to wake up in sweat

THIS. Compared to the ZERO BREEZE Mark 2, the EcoFlow Wave 2 is a bit too heavy and uneasy to carry, moving it up and down the RTT wouldn't be a easy job. Edit: Nighttime is the absolutely best time for this type of unit to work. Using a battery powered portable AC in a poorly insulated RTT during the hot day under direct sunlight is not making sense.

Don't expect a portable A/C with only 5000 BTU's to cool your trailer during the day at 105 F unless your trailer is REALLY well insulated. I've used another brand of battery-powered portable A/C (ZERO BREEZE) in my tent, it will never beat the heat of the sun during the day, best used only as spot coolers. It's at night that they work best, as there is no sun as the biggest source of heat.

Texas here. I understand your pain with heat and humidity. I have an zerobreeze v2 and it works well. I’ve used it on my autohome RTT and it’s wonderful. Allows me to still go camping even tho it’s hot and humid. I usually only run it at night. Allows me to sleep at night comfortably and not lay in my own sweat. The ZB consumes roughly 240W and my 3584WH custom power station is able to run it easily for 14hrs without issue. As other have mentioned, your choice is power supply will greatly determine the success. I run it full power (240w ish) all night and it gets the temp down to low 70s inside my RTT while being 90-95F outside (at night). If you had something like an ecoflow wave that’s more powerful at 550w, you’ll need to be even more conscious about your battery. We can’t all have a 75F blue-sky-California/PNW summers.

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.

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 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.

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.
