This small powerful low profile Model K2 personal cooling system is self-contained, 7 7/8" high and 10 1/4" wide, weighing less than 5 pounds & holds enough water to cool for hours. Plug the 10-foot power cord into a 12-volt power outlet and move it to where cool air is needed in the vehicle or use the Flex Hose Kit to help cool the driver and passenger.

The "blend anywhere" stylish cool gray K2 is strong & lightweight with powerful Twin double ball bearing Brushless Energy Saving motors using less battery power than two clearance lights. The Floating Ball indicates the water level at a glance. Perfect for use in a vehicle unless you can install factory air conditioning.

Set the K2 out of the way and use the Flex Hose Kit (right) to contain and bring the cool air where needed the most. Also used when cool air is needed in two places at the same time. The Flex Hoses are 2.5 inch in diameter by 7 Feet in length and easily cut off to the length you need.

The Smart Cooling Filter in all MightyKool Models like the K2 is the reason it has superior cooling even in more humid areas with water only or ice. It should be changed at least annually or every 200 to 300 hours of cooling. Many add a set of two Smart Cooling Filters for $12, as we pay shipping with any option ordered with a new K2 model.

The seamless K2 is designed to use the optional Air Intake Housing. (left) This allows a superior method of providing Fresh Air ventilation, which is vital to provide maximum cooling when cooling with water or melting ice, however not needed in a moving vehicle, just slow moving types like Farm and Construction types.

Ventilation is vital in a vehicle and the Air Intake Housing is not normally used in a moving vehicle, however in slow or stopped situeations is is very valuable to provide more perfect ventilation and the seven-foot 4" Hose slips off easy when not needed. By placing the hose in or near a window opening fresh air will be drawn directly into the K2 model.

Farmers & Construction workers will be able to control much of the dust problems by using the Air Intake Housing Kit by placing the hose in a window and even cut cheap furnace filters over the hose intake to help keep dust outside the cab along with the Smart Filter inside, also providing fresh clean air.

The K2 contains the easy Top water fill (right) that slides open or closed in one second. The wide opening makes it easy to add water and even ice cubes if preferred. This feature has been a favorite on our WIN3 Model.
The K2 will produce Cooler Air than any portable evaporative Cooler in the World just like our present & previous MightyKool Models, as they do not use a pump. Perfect evaporation is achieved at all times because of the wicking system. When it is Hot and Dry they use more water. Then when it is Hot and Humid they use far less water, which results in creating the Coolest Evaporative cooled air possible.

World-renowned Portable 12-Volt Cooling Systems chilled by our exclusive Smart Cooling Filter Pad. (left) The Smart Pad is at the Heart of the MightyKool Models Cooling Superiority using Water Only without Ice. More Information on cooling with the Smart Cooling Filter. We recommend you order a set with your new cooler to take advantage of the free shipping, as it will need to be changed annually at the very least.

Summary: The self-contained K2 personal cooling system surrounds the driver & passenger with 5 to 25 degrees cooler air than a fan while using water only without ice to produce cool air. Be Cool with a K2 MightyKool! ------
