ZERO BREEZE Mark 3 AC The ZERO BREEZE Mark 3 AC is a game-changer in portable climate control. As the latest model from ZERO BREEZE, it delivers a robust 5,280 BTU cooling capacity in a remarkably compact package weighing just under 22 lb. Ideal for areas between 100 and 150 ft², this unit maintains precise temperature control from 61°F–88°F, making it perfect for campers, tiny homes, vans, or trailers. Built for mobility and versatility, the Mark 3 runs entirely off battery power—no wall plug needed—and can even be solar-powered with its 500 W capability. The dual-hose system enables efficient venting, and condensation is managed via an active drain system. With setup taking only around five minutes and requiring zero installation, it’s a plug-and-play solution for on-the-go living. Among its many modes—Rocket, Cool, Sleep, Fan, Dry, Care, and Heating—the Mark 3 operates at ultra-low power. Its energy-efficient compressor draws just 150 W in basic mode and up to 500 W on full blast. Remarkably, it can drop room temperatures by 20°F in just five minutes. Plus, it also functions as a heater with a 5,800 BTU output, making it a truly year-round climate control companion. Technically impressive under the hood, the Mark 3 operates on 48 V DC (ranging 38–58.5 V), has a four-speed fan, and uses environmentally friendly R290 refrigerant. It's rated for both cooling and heating in ambient conditions between 50°F–104°F and protected against moisture (IPX4). The battery pack (14 lb, 1,022 Wh) features secure lithium-ion cells, supports chainable connections, and offers multiple output ports such as 12 V Anderson, USB-C PD, and USB-A QC, enabling up to 550 W of output, even while charging. Each Mark 3 AC bundle includes the sleek air unit, a 50 V DC wall adapter, a 2.4 GHz wireless remote, drainage and duct accessories, and a thoughtful welcome kit with hoses, adapters, and detailed user manuals. With careful design and high-quality components, it’s a comprehensive kit ready for immediate use—no additional hardware required. Whether you're camping under the stars, hauling across the country, or simply seeking energy-efficient cooling at home, the ZERO BREEZE Mark 3 AC delivers powerful performance in a way no other portable AC unit can match.
