5280 BTU cooling capacity, designed for targeted cooling in outdoor and off-grid environments.

Mark 3 is designed for personal and small-area cooling, with an effective cooling space of 100-150 sq. ft. Unlike traditional air conditioners that aim to cool entire rooms, Mark 3 focuses on spot cooling or flexible cooling for small spaces, making it ideal for outdoor and portable use.

Due to the physics of air conditioning, the front releases cold air while the back releases warm air. Mark 3 includes a heating mode option, but due to power limitations, it is only effective when ambient temperatures are above 50°F (10°C).

The noise level varies depending on the mode:

• Sleep Mode (~46 dB) – Whisper-quiet for night use.
• Standard Mode (~50 dB) – Similar to a small fan.
• Boost Mode (~55 dB) – More powerful cooling, slightly louder.

Up to 7 hours per charge in Sleep Mode. In Rocket Mode (maximum cooling), it lasts about 2-3 hours.

It charges to 80% in 2 hours via AC adapter.

Yes! Mark 3 supports simultaneous charging and usage when connected to AC power or a solar panel.

Mark 3 operates on a 48V system and can be powered by:
1️⃣ AC Power (110V-240V) – The standard adapter is included.
2️⃣ Mark 3 Battery – Official ZeroBreeze lithium battery for off-grid use.
3️⃣ Your existing 48V DC battery system – Requires the Mark 3 DIY Cable. Battery output: >600W, voltage range: 42V-58.8V

4️⃣ Your existing 12V or 24V DC battery system – Requires the 48V Booster. Output power: >650W

Yes! You can swap batteries or connect additional battery packs for extended operation.

Absolutely! It’s perfect for tent camping, rooftop tents, RVs, and overlanding.

Yes! Many truck drivers use Mark 3 for overnight cooling in their sleeper cabins.

Yes! Many pet owners use it for keeping dogs cool in parked cars, travel crates, or pet competitions. Always ensure proper ventilation for safety.

Yes, Mark 3 can provide localized cooling in a car, but it cannot replace built-in vehicle air conditioning, as standard car AC units typically have 12,000+ BTU cooling capacity.

No installation required! Just turn it on, direct the air duct to your cooling area, and enjoy.

Mark 3 includes multiple hoses with different purposes:
✔ No hose needed for direct spot cooling.
✔ Use the air outlet extension tube if you want to extend the cool air.
✔ For enclosed small spaces (like a tent or tiny cabin), connect the dual exhaust hoses to improve efficiency and prevent heat buildup.

It is recommended to clean the air filter every 2-4 weeks and wipe the air vents with a dry cloth.
