What Our Customers Say

★★★★★

“Yes it's expensive but compared to a 12K APU it's damn worth it and must have to every OTR and Regional truck driver. Batteries charge very fast while driving takes about 4 hours for both and each battery gives you at least 5 hours of cooling before it switch to the second battery, you can stack them. ”

“I used my Mark 2 on heck of a lot. It really did what I wanted it to and that was to cool my small sleeper on my 384 Peterbilt. For several years. So far the Mark 3 has potential for me. I like it so far and it gets much cooler that the Mark 2. "

“Delighted to receive Mark 3 and 2 batteries I ordered in September. It will work well in my Hymer Aktiv Class B campervan. Packaging, unit, batteries all top-notch quality. After running it for maybe 5 minutes, I am confident it will be worth the wait. Photo shows output air temperature, running it "bare", no hoses. ”

"I was part of the funding group for this new Zero Breeze Mark3, it just arrived. This thing rocks. It only weighs 22 lbs. Can be run off ac, solar or a clip on battery (1022w). The unit sells for $1299 which is way cheaper than a dc inverter marine AC. I think these will become very popular. I'm using it for boating, camping, garage and when working outside. "

“I am more than happy with my Mark3, is working like a dream. I just sold my EcoWave2 air conditioner as it was extremely cumbersome & very, very heavy to use - my ZeroBreeze Mark3 is far superior on many levels & very easy to use. Thank you for a wonderful product. ”

"I have owned approx 2500 aircraft and been flying for 40+ years. With the air in the cabin similar to a car with no airflow in the Summer it can be 130 degrees until you get to altitude. So far the Mark 3 is pretty nice. I put the outlet hose between the 2 front seats so it cools the front of the aircraft well. This really is one of the best things to come along for flying in the Summer. It's portable and doesn't physically connect to the plane. "

A Decade of Commitment

We weren't the first to imagine portable AC, but we've spent nearly a decade making it real. Across three generations of outdoor air conditioners, we've pushed boundaries and refined every detail. While others settled for compromises, we stayed true to one belief: true portability matters.

Our mission is simple. We want to ease outdoor living with innovations. That's why we focus on building compact, powerful, and reliable solutions that help outdoor people stay cool, safe, and refreshed wherever they go.
