MightyKool Model K2 Cools you in your Truck Sleeper with Water Only (no Ice)

Reduce Idling while Sleeping, Loading/Unloading with a 12-Volt Cooling System

"I am really impressed with the (MightyKool) cooler, and it has already paid for itself 100 times in fuel savings over the last 3 years. Most of my loads go back and forth from the NW US to the NE US, and sometimes down the Texas area. The more I stay north, the better the cooler works for me. I have no problem with battery drain; I usually run it all night. It is nice and quiet, and I highly recommend this unit to anyone who likes a cool breeze and to save LOTS of Cash at the same time." (Owner-Operator) J. S. Beggs, OK (Other Testimonials)

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 all night. Plug the 10-foot power cord into a 12-volt power outlet and move it to where cool air is needed in the sleeper or up front when loading or unloading. We recommend the optional Air Intake Housing below for Sleepers especially in humid areas.

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 Sleeper and while loading or unloading.

The seamless K2 is designed to use the optional Air Intake Housing. (right) This allows a superior method of providing Fresh Air ventilation, which is vital to provide maximum cooling when cooling with water or melting ice. Note the Water Fill on the top in Black.

Ventilation is vital in a sleeper while parked especially in humid areas. The purpose of the Air Intake Housing is 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.

The K2 contains the easy Top water fill (left) 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.

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.

Models that use ice must have pumps plus heat exchangers and use at least 20 pounds of Ice Per Hour during the daytime. Otherwise they are not true 12-volt air conditioners and will produce humidity just like the ones that claim to be air conditioners and just blow air across ice.

Summary: The self-contained K2 personal cooling system surrounds people or pets 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! ------ Specification/Dimensions all models:

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.

NOTE: It takes an air conditioner to cool any area, however there is no such thing in the world as a self-contained 12-volt air conditioner. To cool your Sleeper for 5 hours during the day takes approximately 100 pounds of real ice & a proper cooling system, therefore if interested Click here.
