"Absolutely love how portable the Mark 2 is. We take it everywhere with our RV. It's perfect for those hot summer days when you just need a break from the heat."




"Installing the Mark 2 in our rooftop tent was straightforward, and it drastically improved our comfort on hot nights. Highly recommend for anyone who hates sleeping in the heat!"




"We’ve been using ours in our patriot x3 camper trailer all summer. It’s really easy and it works! Our camper has a canvas pop up style tent so i was worried it wouldn’t hold the cold air in but it does. It gets so cold that we have to turn it down or off completely in the middle of the night. It’s expensive but very well worth it for the summer. “

Mark 2 in Action

Watch how the Mark 2 AC transforms a heated insulated tent into a cool haven during the peak of summer.

Baum's test of the ZERO BREEZE Mark 2 portable air conditioner in an insulated tent dramatically lowered temperatures from a high starting point during the day to a much more comfortable level, demonstrating its cooling efficacy in hot conditions.

  • 4:42 PM: Starting temperature was 93.2°F.
  • 6:03 PM: Temperature quickly dropped to 66°F.
  • 7:10 PM: Temperature continued to decrease to 54°F. 
  • 9:44 AM the next day: Temperature stabilized at 60°F.

Usage Recommendations:
While this test was conducted in an insulated tent, the Mark 2 AC is also suitable for various non-insulated tents and rooftop tents, especially effective during nighttime use to provide the necessary cooling.
Although the air conditioner was placed inside the tent for this test, it is recommended to externalize the unit when using RTTs or other outdoor tents to save space and simplify the drainage process.
