Mark 3 Portable AC + 2 Batteries

What Our Gearhead® Experts Are Saying:

"I took the Mark 3 setup on a week of off-grid camping last August and it completely changed how I approach summer trips. Two batteries gave me enough runtime to sleep cool through back-to-back hot nights, and the pass-through solar charging kept both topped up during the day without any stress about running out of power after dark."

Hot summer nights in camp have a way of undoing everything good about a trip, and the Zero Breeze Mark 3 Portable AC + 2 Batteries is the setup that puts that problem to rest for good. This is a complete off-grid climate system, not a collection of parts to figure out separately. The Mark 3 AC delivers 5,280 BTU of true cooling power through a dual-hose design into tents, vans, rooftop setups, and small cabins, while the two included 1022Wh batteries provide the runtime to keep it running through a full night and well into the next morning without a wall outlet anywhere in sight.

Seven modes cover cooling, heating, and dehumidifying across a wide temperature range, so the kit earns its place in the truck across three seasons rather than sitting idle once midsummer passes. The 48V DC power system accepts up to 500W of solar input, and pass-through charging means the AC keeps running while the batteries recharge from panels, a vehicle port, or a wall outlet whenever one becomes available. Two batteries also means one can charge while the other runs, extending off-grid capability further than a single battery setup allows. At 46 dB in sleep mode the Mark 3 runs quietly enough to sleep through, the included wireless remote handles temperature adjustments without leaving the sleeping bag, and USB-A, USB-C, and 12V Anderson outputs on each battery keep phones, lights, and other camp gear powered alongside the AC.
