Built for the Journey
No tangles, no toolbox. With an integrated cable and covered ports, plus two ergonomic rubber handles, the Mark 3 battery is ready to roll with you whether you're using it at a campground, in a van, on a semi-truck, under a rooftop tent or on a boat.
Charge It Your Way
Mark 3 Battery supports multiple recharging options to meet your needs—on the road, off the grid, or at home.
12V Car Cigarette Lighter
Top up your Mark 3 battery on the move with your car's 12V socket. Ideal for travel days, road trips, or charging between stops.
12V-60V Solar Charging Panels
You can connect solar panels to charge your battery when you're camping, boating, or in any remote location. The built-in 500W MPPT solar controller helps optimize charging and can recharge up to 80% in around 2 hours with strong sunlight.
Mark 3 AC Adapter
When you're near a power outlet, such as at home, in a cabin, or with a portable power station, you can quickly recharge the battery from 0% to 80% in just 2 hours using the included adapter.
*Note: The car cigarette lighter cable and solar charging cable are sold separately.
Stay Cool With Continuous Power
Pass-Through Charging
Keep cooling while charging. The Mark 3 battery supports pass-through charging, so you never have to stop the AC to top up your power.
Stackable Battery Expansion
The Mark 3 battery supports up to 10 connected units to ensure continuous cooling, even during long trips or off-grid use.
Made to Work as One
The Mark 3 battery is made specifically for the Mark 3 AC. It locks securely under the unit using alignment latches, creating a clean and stable fit. Once connected, it shares key information with the AC in real time, including battery level, estimated runtime, and charging status, which are all visible on the remote or app. It also supports direct DC charging through the proprietary connector, with no extra accessories needed. Everything works together as one simple, seamless system.
Power for More Than Cooling
While it's purpose-built for the Mark 3 AC, this battery also works great on its own. With built-in USB-A, USB-C, and 12V Anderson outputs, it can power laptops, drones, lights, phones, and more. Whether you're off-grid or on the move, the Mark 3 battery is ready to serve as your reliable, standalone outdoor power source.
Choose Your Power Setup
Not sure how many batteries to bring? Here's how to choose based on your cooling needs.
- One Battery
If you're planning to take a nap, get some light sleep, or just enjoy a brief cooling break for about 2 to 3 hours, one battery is usually enough.
- Two Batteries
If you want to sleep through the night, such as for 8 to 10 hours, two batteries are a more suitable choice.
- Three Batteries or More
If you plan to use the Mark 3 at its maximum setting as a spot cooler while working in extreme heat, having three or more batteries gives you the flexibility and peace of mind for continuous operation.
