The KoolMAX has all the tools you need for music on the go. Choose from FM radio, Bluetooth, SD card, USB drive, and AUX music inputs. It even has XLR and 0.25 inch microphone and instrument inputs. The built-in digital amplifier lets you plug in a guitar, and jam out.

KoolMAX boasts an unmatched stereo sound system. Two 2" high-performance tweeters, and two 6.5" high-fidelity speakers deliver crisp, clean sound. The KoolMAX is water-resistant, so you can safely take it through the rain. Just don't drop it in the ocean!

The rechargeable battery delivers up to 16-hours of playback time, enough to keep the music going for extended trips. When it's time to recharge, use the included wall power (AC) and cigarette lighter (DC) adapters to recharge at home or from your vehicle.


The KoolMAX was designed to make every aspect of a weekend trip easier. The long telescoping handle lets you easily roll the cooler on its heavy-duty wheels. When the terrain is too rocky, the large side handles make carrying the cooler a cinch. Treat yourself to a cold one with the bottle openers built-in to the handle.

When it's time to head out, store your valuables and electronics in the weather-resistant storage compartment. To secure your gear, use the built-in tie-down loops to run bungee or elastic cords across the cooler.
