You just crushed a drive. Now, the cart feels like a 120-degree sauna. The seat burns through your shorts. The breeze is just more hot air. By the 10th tee, your grip is sweaty, your focus is shot, and you're mentally spent — not from the game, but from the ride.
Ice coolers melt in an hour. Misting fans just add sticky humidity. You deserve better than surviving the course.
Meet the Mark 3 — the first portable AC with a real compressor that runs on swappable batteries. It blasts 20°F colder air in 5 minutes. Not a damp mist. Not a fan.
And because two cool golfers are better than one, the Mark 3's setup directs crisp, dry air to both seats. Allow you and your partner stay sharp, focused, and actually enjoy the ride between holes.
"I've been taking the Mark 3 out for a few rounds every week. Even in an open-air golf cart, the air coming out is noticeably cold. Running it on Turbo mode with a dual-battery setup gives me about 4.5 hours of continuous, crisp relief, plenty for a full round. It's a massive step up from my old ice-driven cooler. It just works."

"I designed a custom setup for my Mark 3 to beat the 100-degree Louisiana heat. By installing a custom bracket in the rear basket and a ceiling-mounted duct system using PVC pipe, I can distribute cold air efficiently throughout the cabin. The system reliably powers through 24 holes of play, with air output measured at a crisp 68°F. It's a seamless, powerful integration that keeps every passenger cool until the final putt."

Unlike ice-driven units that require constant refills and lose cooling power as the ice melts, Mark 3 is a true compressor-based AC. It delivers stable, crisp air regardless of the outside temperature or humidity. No ice, no mess, just continuous cooling until the final putt.
In an open cart, direct airflow provides immediate spot cooling to keep you fresh. For a full-cabin experience similar to a car, we recommend using a transparent enclosure to trap the cold air and maximize efficiency.
Yes. Field tests show that a single dedicated battery is typically sufficient for a standard 4-hour round. For extended play or double rounds, a dual-battery setup is recommended.

Not at all. The Mark 3 is remarkably compact. Most golfers place it in the rear basket behind the seats or on a mounting bracket above the bag well; some even keep it right on the passenger seat for solo rounds. Its slim profile ensures it stays out of the way, leaving plenty of room for your golf bags and other essentials.
