Mark 2 Portable AC
Brief product introduction
ZERO BREEZE Mark 2 was created to solve the problem of enjoying coolness in outdoor freely. Because the existing portable air conditioners are bulky and power-hungry. They are not for outdoor. Max designed a first real portable battery-powered air conditioner which is impossible as considered by traditional air-conditioning industry experts.
2300BTU Mark 2 AC runs with its battery for 3~5 hours. About 1/5 power consumption of conventional air conditioners. No generator, water or ice required. Weighs only 16.5lbs. Take and go easily.
Mark 2 is not limited by the power supply and is free to use anywhere, such as in tents, camping, the RV, in the car, outdoor sports, boats, small aircrafts, or any place you need it.
ZERO BREEZE Mark 2 comes in 3 types and all of them have the same functions and features, what makes them different is the extra battery feature which is optional to purchase.
The Basic – No batteries (Powered by shore)
The PLUS – One battery (Up to 6 hrs cooling)
The PLUS EXTRA – Two batteries. (Up to 12 hrs cooling)

Explanation of technical terms
What BTU Stands For?
According to EIA, A British thermal unit (Btu) is a measure of the heat content of fuels or energy sources. It is the quantity of heat required to raise the temperature of one pound of liquid water by 1 degree Fahrenheit at the temperature that water has its greatest density (approximately 39 degrees Fahrenheit).
What BTUs Mean to Your AC?
Air conditioners come with BTU ratings. This rating substantially tells you how powerful the unit is. Air conditioners remove heat from the air and circulate cool air back in. Here, BTUs measure how much heat is removed per hour.

The power consumption is related to the working mode, the airflow, the humidity, and the temperature of the environment. Its EER rating is 9.58. This means that Mark 2 has the highest energy efficiency rating.
Rocket or cool mode: 150~240W(3~5h)
Sleep mode: 120~150W(5~7h)
Fan mode: about 20W(42h)
ZERO BREEZE Mark 2 AC uses R134A refrigerant. No need for ice or water. The feedback data of the engineer will not require any adjustment for normal operation for at least 4 years. Unless the air conditioner fails, please contact email@example.com or submit troubleshooting.
The Sound Level of Mark 2 is 52dB (A).
ZERO BREEZE declined the option of the cheap and conventional home AC compressors.
The 24V Micro Inverter Compressor
As the core of the air conditioner, ZERO BREEZE clearly specified that the small size, lightweight, low power consumption, and DC compressor are the preferred goals of Mark 2. To achieve this goal, we worked hard with professional refrigeration engineers, compressor R&D experts, leading manufacturers.
Bringing compressors, which can exclusively be used for special equipment, into daily life.
Now, Mark 2's compressor is about the same size as a cola can, less than a quarter of the size and weight of conventional compressors. It indeed costs 4 times more than a conventional compressor, but truly worth it. Because this is what rocks the portable air conditioner market.
The ZERO BREEZE Mark 2 generates 2x the cooling power with 2300 BTU and 40% higher cooling efficiency compared with Mark 1.
Temperature of the breeze drops 30°F / 10℃ Within 10 mins.
*Operating in a 96°F/36℃ laboratory can roughly reflect the performance of the ZERO BREEZE Mark 2.
When we are going to cool down a given size space, the cooling effect is closely related to the number of people inside, the insulation condition, the sun exposure, and so on.
Based on our test, it’s ideal cooling space is 25~40 sq ft, while the ambient temperature is 100F/38C, humidity is about 50%, no direct sunlight, good insulation condition, and the temperature can be reduced by 9-22°F/5-10°C.
Mark 2 is helpful in practically any space. Use Mark 2 as a spot cooler when you are in a large space. When working at maximum speed, the cool air can be blown as far as 0.08 inches (2 meters).
No. Mark 2 is a real air conditioner with compressor. No water or ice needed.
It takes about 6 hours to charge up the battery by official power adapter.
When all the indicators stop flashing, the battery is fully charged. It can be used for 3.5～5 hours.
The battery can be charged and discharged over 500 times but it will eventually wear out.
We have US, CN, JP, AU, EU and UK standard.
We will deliver the socket according to the customer's receiving address. Customers can also note the required socket specifications when placing an order.
Shore power is also available.
Or you can use Mark 2 AC with Mark 2 battery for 5 hours cooling. It takes about 6 hours to charge a battery fully. It can be charged by solar, in-car charging. Or use your own battery to power Mark 2 AC.
The 24V compressor and 24V drive circuit will generate less current, improve the efficiency and battery running time under the condition of the same cooling power.
The car mode was made to avoid draining your car battery completely when powering your Mark 2.
In default mode, when the power supply voltage is lower than 18.6V, the air conditioner will stop working automatically.
Press and hold the “+” and “-”button at the same time (hold for 2 seconds), Mark 2 will enter the car mode (tail indicator light will be purple). In this mode, when the power supply voltage is lower than 22.3V, the air conditioner will automatically power off to prevent the car battery from running out.
When the “+” and “-” button are pressed and hold for 2 seconds again, it switches to the default mode.
With dual hose venting heat system, the heat is removed from inside to outside through Mark 2 AC.
One hose takes in the outside air, then the air flows across the condenser. The heat is transferred to the refrigerant and finally released into the outside air through another hose.
The best way to cool down a limited space is to connect the two hoses and separate them slightly out of the window or outside the door. Both are in the Mark 2 box.
ZERO BREEZE had integrated a revolutionary dual hose system to draw in fresh outside air and exhaust hot air through another hose.
Dual Hose allows an intake hose to be used to circulate fresh air inside. No negative pressure in the room. And it provides a better performance and maximized output cooling power.
The Mark 2 battery package includes two foam adapters. So if you ordered the battery, you can use the foam adapter to extend the hoses to the outside.
Outer diameter: 4.37in/11.1cm
Inner diameter: 3.94in/10cm
1. The Mark 2 AC should be kept level when it's running. It is best to lean it backward 5-10 degrees, not forward, left or right. Otherwise the condensed water will leak from the front, side or bottom of the air conditioner.
2. Do not move the Mark 2 AC immediately after using it. Tilt the Mark 2 AC backwards slowly by 30 degrees to ensure that the water in the Mark 2 AC is drained.
Note: if there is leakage due to improper placement, there is no need to be nervous, just wipe it or cool it naturally, it will not affect the performance of the unit.
Outer diameter: 0.55in/1.4cm

Accessories to upgrade your experience.
The Mark 2 battery can be charged from a 12V power source like your own power station or vehicle power through the 12V to 24V DC-DC Converter.
There are two functional connectors, one is for a 12V car cigarette interface, and the other is for wiring directly to your 12V battery positive and negative electrodes.
ZERO BREEZE Mark 2 can be powered by 24V battery or power adapter to access 110-240V power supply. Its maximum power is about 210W, and the maximum current is about 9A.
Make sure your 24V battery can provide enough power (210W) before using your own battery. And you need the DIY cord with GX16-4 connector can be used to power Mark 2.
If you have a 110V-240V inverter power system which has more than 250W power, you can use the adapter comes with Mark 2 to make the air conditioner work.
Please pay attention to the following essentials.
1. Check the battery output interface for voltage output.
2. If the battery is 24V DC output, the DIY cord with GX16-4 connector can be used to power Mark 2.
3. If the battery is 110/220V AC output, you can use the Mark2's own adapter to connect to supply power.
4. If it is another output voltage, you need to use our dedicated converter to ensure that the voltage connected to the air conditioner is 24V. For example, if your battery output is 12V, then you may need such a converter.
Please note that when using your own battery to power the Mark 2, you will need to be aware of your operation. ZERO BREEZE will not be responsible for damage caused by your operation. Watch more.
EcoFlow, Goal Zero and Bluetti are three brand power stations that support DC power, which can charge Mark 2.
To power your air conditioner with a power station, the first thing you need to check is that your power station provides the same voltage as your air conditioner. If not, you will need a power converter. For example, if the power station output is 12V and your air conditioner input is 24V, then you need a 12V to 24V converter.
Here are the accessories required for the available models.
Cleaning and storage
For safety purposes, please turn off the power and unplug the cord before working on the Mark 2 unit.
Remove and clean the filter.
We recommend using a vacuum cleaner to clean the condenser and evaporator of the Mark 2 unit.
It is recommended that the Mark 2 unit be cleaned before storage.
To extend the battery life of the Mark 2, you need to charge it to about 80% (shows 4 blue indicators) before storing it. If your storage time is more than 6 months, it is recommended to check the remaining charge every 6 months and charge to 80% when it is below 20%(shows 1 blue indicator).
We have designed a perfect size bag for the ZERO BREEZE Mark 2 air conditioner and its accessories. If you are interested, please contact customer service. firstname.lastname@example.org
Never store your air conditioner on its side, as this can damage it.
It’s best to store the AC unit in an area that is cool and dry.
The Infrared remote control can reach up to 39in/1m. You can reflect the signal off shiny things and it will still work.
Controller physically oriented towards the receiver, no obstacles, and no disturbance of other light sources. The receiver is located in the center of the control panel of the Mark 2 air conditioner.
No. Considering that the cooling capacity of Mark 2 is 2300BTU/h , which is quite different from traditional home or car air conditioners.
It is not yet possible to achieve constant temperature control in a specific size space. When we are going to cool down a given size space, the cooling effect is closely related to the number of people inside, the insulation condition, the sun exposure, and so on.
Mark 2 has a temperature display at the air outlet, which shows the blowing temperature. You can adjust the temperature of the blown air by selecting different working mode and air volume.
E03 code means low voltage protection.
The unit shuts off, buzzer alarms, and tail LED light flashes. The battery runs out. And in normal mode: the output voltage is lower than 18.6V; in car mode: the output voltage is lower than 22.3V.
Please charge the battery to meet the input requirement of the Mark 2 AC’s output voltage.
Mark 1 Portable AC
An extra cord with an Aviation connector is needed.
No, you won't be able to run ZERO BREEZE without being "plugged in" if you don't purchase the additional battery.
Using the ZERO BREEZE in a car or truck for short periods of time is ideal for use with the 12V battery. ZERO BREEZE allows you to use AC in situations like waiting in the carpool line, eating lunch, or grabbing a quick nap in your car during a work break. Of course, never leave your pet alone in a warm vehicle as this could lead to harm to your pet. For that reason, we do not recommend using the ZERO BREEZE for that purpose.
