Mark 3 AC Only: 22" L x 10" W x 12" H (56 cm x 26 cm x 31 cm) and 22 lbs (10 kg) Mark 3 Plus: 22"L x 10"W x 16"H and 36 lbs

What is the cooling area of the Mark 3?

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.

How long does the battery last on a full charge?

One Mark 3 battery can run 2-7h on a single charge. It depends on the running mode and the environment you are in.

Can the Mark 2 battery be used with Mark 3?

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.

How is heat removed through the ZERO BREEZE Mark 3?

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.

How does the Mark 3 drain?

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.

Can the heater operate at temperatures below 50℉/10°C? The specs mention 50℉/10°C minimum. Will it cause any damage to operate under 50℉/10°C?

If Mark 3 is operated at temperatures below 50℉/10°C, the evaporator may freeze, triggering the unit's protective mechanism, which will cause it to stop working.

How long is the warranty for this product?

Purchases from the official website come with a 1-year warranty.

Tired of Sweating Through Your Breaks? Long hours on the road wear you down, but when it’s finally time to rest, your cab feels like an oven—hot, stuffy, and impossible to relax in. You need a break to stay compliant with DOT’s 10-hour rule, but cooling down isn’t so simple. Running your truck’s AC means idling the engine, which can violate state or company idling restrictions, waste fuel, and put unnecessary wear on your engine. You’re stuck between sweating through your break or risking fines and maintenance costs.

And when you're waiting at a loading dock under the scorching sun, there's no escape from the heat. If you travel with a pet, it’s even worse—their body temperature is naturally higher, and they overheat faster.

So is there a way to stay cool without breaking the rules or wasting fuel?

YES! ZERO BREEZE Mark 3 has you covered. No idling. No extra fuel costs. Just portable, powerful cooling whenever you need it.

Portable and Flexible

At just 22" × 10" × 12" and 22 lbs, the Mark 3 is easy to transport, set up and store, designed for life on the move. Use it in your cab, at loading docks, or even under the truck while making repairs. Wherever you need a break from the heat, the Mark 3 delivers.

A truck driver in a safety vest carries the ZERO BREEZE Mark 3 portable air conditioner into the cab of a semi-truck at sunset, preparing for sleeper cooling.

ZERO BREEZE Mark 3 portable air conditioner is in use inside a truck sleeper cabin, cooling a resting man with a front air outlet duct while he uses his phone.

Battery-Powered Convenience

No need for shore power or idling. The Mark 3 runs on a rechargeable battery, providing 2–7 hours of cooling per charge, depending on the mode. Recharging is easy—use your truck’s cigarette lighter, solar panels, or a portable power station. Want longer runtime? Stack extra batteries and stay cool for as long as you need.

Powerful, Cost-Effective Cooling

With 5,280 BTU cooling power and a 10.56 EER, the Mark 3 offers efficient, fuel-free comfort that saves you money. No more running the engine just for AC. No more unnecessary fuel costs. Just turn it on and enjoy powerful cooling while protecting your engine from extra wear.

Mark 3 is placed on the hood of a Freightliner semi-truck.

Ducts Installation

Maximize cooling with the diy window kit. It easily routes the Mark 3's exhaust outside, keeping hot air, bugs, and rain out of your cab.
