Questions and answers

How much does the Zero Breeze Mark 3 cost?
The best new price is $1,005.00 at eBay as of November 8, 2026. Six stores list it new, so compare bundle contents before buying.
How long does it run on the included batteries?
Runtime depends on cooling mode and ambient heat; the two included 18650 packs are meant to be swapped so one charges while the other runs. Expect hours, not a full day, at full cooling.
Can it run while plugged into a car or solar setup?
Yes. It accepts 18–36V DC input, so it can run from a 12V/24V battery bank or solar system through a suitable DC supply, and it also charges over USB-C Power Delivery.
How big a space can it cool?
It is built for small, enclosed spaces such as a sailboat cabin, RV bedroom or tent. It is not a substitute for a room air conditioner in an open house.
What comes in the box?
The unit, two battery packs, a charging cable, a cable for the Mark 2 AC and one window slider. No charging station or stand is included.
Is it safe to use outdoors in rain?
It has IPX4 moisture protection, which handles splashes but not heavy rain or submersion. Keep it sheltered in wet weather.
