Zero Breeze

Mark 3 Plus Extra Portable AC

What Our Gearhead® Experts Are Saying:

"I ran the Mark 3 Plus out of a van on a desert trip where afternoon temperatures were genuinely brutal, and it dropped the interior temperature noticeably within the first few minutes of turning it on. The fact that it runs on battery and can pull power from a solar setup meant I never had to worry about finding a hookup or burning through a generator just to sleep comfortably."

Summer basecamp in the desert, a van parked in a dusty lot after a long day on trail, a tiny house baking in afternoon sun with nowhere to hide. These are the moments the Zero Breeze Mark 3 Plus was designed for. At just under 22 pounds, it is the smallest and lightest 5,280 BTU portable air conditioner on the market, and it sets up in five minutes without drilling, running cords, or hunting for a power outlet. Battery powered and solar compatible up to 500 watts, it goes wherever the adventure does.

Once it is running, the Mark 3 Plus gets to work fast, dropping ambient temperature by 20 degrees Fahrenheit in as little as five minutes. A built-in thermostat lets you dial in anywhere between 61 and 88 degrees to match exactly how you want your space to feel, and the dehumidify function pulls moisture out of the air to keep things comfortable even when the humidity climbs. An active drain system handles condensation automatically so there is no bucket to empty or mess to manage. When nights get cool and the season shifts, the dual function heating mode means the Mark 3 Plus earns its place in your kit year round.
