ZERO BREEZE Mark 3 Portable AC
Finding a sustainable way to enjoy off-grid air conditioning has always been a challenge, especially during the sweltering summer nights. Whether equipped with a roof AC and a high-capacity power setup or not, traditional systems can provide intense cooling while connected to shore power, but often fail to offer sustainable comfort during the unconnected, tense overnight stays in nature.
The Mark 3 AC revolutionizes this experience. In van life, we need to think differently than home air conditioning—energy is precious, and we need to use it wisely to ensure comfort when and where it's most needed.
Unlike traditional air conditioners that drain your vehicle battery overnight, the Mark 3 AC is designed for energy efficiency. It allows you to cool only your sleeping area by using a curtain separation, preventing energy waste from cooling the entire vehicle.
The Mark 3 consumes between 150 and 500 watts, depending on the environment and setting. With a full charge, the 1022Wh battery can typically run the Mark 3 for 5 to 7 hours, providing enough power for a restful night's sleep.
Simple Setup
The Mark 3 AC makes cooling effortless for van life. No vehicle modifications or complicated installations required. Simply place the unit near your sleeping area, extend the dual-duct system through a window, and turn it on.
Focused Cooling
With a powerful 5280 BTU output, the Mark 3 AC provides targeted cooling directly to your sleeping area—no need to cool the entire vehicle. This focused cooling approach ensures you stay comfortable while using minimal energy.
Cost-Effective Performance
Energy Efficiency
The 5280 BTU Mark 3 operates at just 500W at peak power—about one-third the consumption of typical 5000 BTU window ACs. This dramatically reduces electricity costs and minimizes battery strain.
Affordable Operation
Unlike traditional ACs that require large generators or costly solar systems, the Mark 3 keeps operational costs low with its efficient power usage.
Minimal Maintenance
With a streamlined design and no bulky components, the Mark 3 requires less maintenance, saving you on repairs and upkeep.

So glad I bought this right before the hottest summer in world history. I appreciate the Zero Breeze most at night. I cannot sleep if it’s hot and humid. This unit not only removes humidity from my campervan, it cools it to a comfortable temperature.
It also uses only 150 watts in sleep mode which is critical when you rely on solar. There is no sun at night! I really can’t think of anything negative to say about this product.

surviving the NYC summer was no easy task. I thought a 5K btu air conditioner is enough to cool my Sprinter campervan but it wasn’t! Although the window-type AC can run for 6 hours using my Bluetti AC200 Max + B230 module, it’s simply not enough to be comfortable.
Hence comes the ZeroBreeze! ZB (150-300 watts) uses less than half of wattage compared to 5K window-type AC (350-800 watts) which means it can run using my bluetti for atleast 16 hours.

Day one of using my ZERO BREEZE AC, I was very surprised how nice and cool the van got. It was 85 degrees and humid outside. Within an hour and a half of running the ZERO BREEZE the van 🚐 was in the 70s and significantly less humid. Comfortable enough to sleep in.

5,280 BTU can typically cool a small room or an area of about 100 to 150 square feet. However, this can vary based on factors like ceiling height, insulation quality, local climate, and the number of windows and doors.
One Mark 3 battery can run 2-7h on a single charge. It depends on the running mode and the environment you are in.
Yes.
The Mark 3 uses a dual-hose system to expel heat. The process is similar to the Mark 2. One hose draws in outside air, which then flows through the condenser. The heat from the condenser is finally expelled outside through the second hose.
There is a pump inside the Mark 3 and a sensor placed in the tray. When a certain amount of water accumulates, it will drain automatically, eliminating the need to manually tilt it to drain.

If Mark 3 is operated at temperatures below 10°C, the evaporator may freeze, triggering the unit's protective mechanism, which will cause it to stop working.
Purchases from the official website come with a 1-year warranty.
One Mark 2 battery can charge one Mark 3 battery at present. If you have two Mark 2 batteries, they can be used in series with a DlY cable to power the Mark 3 directly.
