A little water. A little power. A lot more livable.

The useful difference

Small footprint. Serious relief.

Cool the person, not the claim.

The K2 directs a cool breeze where you need it. It is not pretending to air-condition a whole vehicle.

Power that travels.

Choose between 10 and 30 watts on a 12-volt source, whether you’re parked up or off the beaten path.

Carry-on compact.

At roughly 8 inches tall and under 5 pounds empty, it earns its place in a sleeper, boat, tent, or camper.

Ships like you mean it.

Free shipping in the continental USA, typically out the door within 24–48 hours Monday through Thursday.

A simple exchange

Evaporation does the heavy lifting.

The fan draws in outside air and moves it through water-charged evaporative media. That air comes back out cooler, creating a personal breeze around you or your pet.

01 / Draw

Outside air enters through the compact housing.

02 / Cool

Evaporative media takes the edge off before the breeze reaches you.

Cool the driver and passenger. Not the vehicle.

If your vehicle lacks A/C, the 12-volt K2V helps cool the Driver and Passenger, however not the vehicle itself. It is made for focused relief in sleepers, vans, boats, campers, tailgates, and long drives with a pet.
