Truck Sleeper Portable 12-Volt Air Cooling Systems
[Home Frequently Asked Questions 12-volt Models Testimonials Prices]


Sleep in Comfort without idling while using less Battery energy than 2 clearance lights. Cool yourself in your sleeper using Water Only without Ice instead of using several Heavy Duty Batteries or an APU! The Portable 12-Volt Cooling System WIN3 or MW2 will typically do what you need with proper ventilation for less than $500.00 including S/H into the Continental USA.

Both the MW2 (left) & WIN3 (right) are small, weighing 4.25 & 6.25 pounds respectively dry. The WIN3 holds enough water to cool for 8 to 12 hours at a time. The MW2 holds enough water to cool for 2 to 4 hours & uses the Water Kit to sleep for 8 hours or more.


Just plug in the 10-foot cigarette lighter cord, then set either small Cooling System out of the way. Add water then use the 3-Speed Switch to turn on low, medium or high and place the 2 1/2 diameter hoses in the best position either in the Sleeper area or up front when loading or unloading without idling.

Combine the WIN3 or MW2 with the Flex Hose Kit 2 (left) and you typically have all the cooling you need in either Humid or Dry climates using Water only. Click on the Flex Hose Kit 2 to see why you need this Option, especially in a Humid area. You may order one set of two Custom Cooling Filters when ordering any MightyKool Model, as there is no additional Shipping or Handling charge. The single Filter will last from 200 to 400 hours of use before needing changing.

The WIN3 or MW2 has 15 to 20% more Cooling Velocity than the Model MW1
(right) when using the Flex Hose Kit. Therefore, the 12-Volt MW1 is not normally recommended with the Flex Hose Kit. However the MW1 with the Water Kit is used without the Flex Hose Kit for Sleepers, in the Dry Climates of the West.


The MW1 Combo is sale priced at $321.00 including delivery within the Continental USA. The Combo includes the MW1, Water Kit plus Extra Custom Cooling Filters (sales tax extra in AZ). If you still lay over in areas of Humidity in the West or travel East, then it is important to switch to the WIN3 Combo for a small extra investment.

If money and buying Ice is no problem consider the12-Volt Air Conditioner MK3, (left) for colder air, without the Flex Hose Kit & uses less energy than 4 clearance lights. This MK3 pumps "Ice Water" for Air Conditioning, which takes about 12 pounds of ice PER HOUR during the night & 20 pounds of ice Per hour During the day.


Use one of our Portable 12-Volt Cooling Systems in your Sleeper, then move the Cool Air provided up front for use while you are waiting to load or unload without idling your engine. Your investment is paid for quickly with the savings on fuel alone, not counting wear and tear on the engine.

If you drew a line through the middle of North Dakota continuing south into the Gulf you would typically cool with water only West of the line in dry areas or ice & water East of the line in humid areas for comfort. Of course you may use water only in humid areas if you would be satisfied with 10 or 15 degree cooler air than a fan would produce.



There are two small 5/8* water hoses pumping water in and out of the MK3. One of which contains a pump that forces 300 gallons of water every hour through the Copper evaporator. The other returns the water back into the ice chest siphoning condensation with it creating a dry closed system. If you are interested to learn more about this type of Air Conditioner that uses Ice Water Click Here .


When you need to eliminate excess water from the ice chest, merely take the return line and put it out the door, turn on the MK3 and it will pump out the water in a minute or two. Therefore you never need to move or remove your ice chest.


A few Testimonials:
I just want to tell you that doing business with you has been great and that the customer service has been excellent. The unit works great I am a truck driver works for Knights Transportation out of Phoenix,AZ and at times have to sleep in my truck in Phoenix when the outside temp is still over 100 and all I do is open the 2 top sleeper vents for fresh air and turn the unit on high and can sleep all night without wakeing up. I have told other drivers about it and showed them how good it works and they say they going to order one for themselfs. Thank you. C. G. Tucson, AZ.


My husband did have a chance to use his (MW1) this last week in California. The temperature was into the nineties in the daytime and he was able to sleep in the sleeper with his Swampy running. He is very pleased with this purchase. Thanks, M.A. Battle Mountain, NV


We shipped another MW1 on June 4, 2008 to R.N. of Carrollton, GA. as he said even if he gets to use it a few nights it will pay for itself quickly in Fuel Savings. He just did not want to deal with the ice as he feels he can normally get by just fine with the 10 to 15 degree cooler air than just a fan. If it is too uncomfortable because of higher than normal heat and humidity he can still crank up the engine. (NOTE: Since then we developed the WIN3 and the Flex Hose Kit, which is much better).


T.D. of Atlanta, GA. called 06/03/2008 to order additional cooling filters as she purchased a MW1 for her husband for his truck Sleeper in 2005. When she ordered the MW1 we explained that this type of cooling was not as effective in a humid area as it is in a dry area. She ordered it anyway and her husband says it blows cool air while he sleeps plus has saved a lot of Fuel these past two years. (See NOTE above)


USED THE MK3 FOR SLEEPING IN THE DRY DESERT PLUS HUMID AREAS:
I purchased a MK3 as a gift for my husband who works in the tropics and outback desert areas of Australia. I was optimistic that the dual cooler/air-conditioner would give him some relief from the heat. He recently passed through the Opal Mining Town of Coober Pedy where they build their homes underground to beat the heat and the temperature there was 54 degrees Celsius (130 Degrees Fahrenheit). He sleeps in the back canopy area of a utility while on the road working and he tells me THE MK3 IS FANTASTIC! On the low setting it cools the sleeping area (using water only) and he has no trouble sleeping at all. With ice (in the Humid Tropics) and on a higher setting he pulled a sleeping bag over himself because he was too cool! I want to thank you for a great product and tremendous customer service. My husband has recommended you to other drivers and they will be in touch with you soon. TOO COOL! K.R. Blackwall Australia


Just to let you know I am a local truck driver here in the valley and my company like many out there nowadays don't want us to idle when we get stuck somewhere waiting to get loaded or unloaded. Well today I got stuck sitting at one of the shippers over in Tolleson for about 4 hours and while my buddies in the trucks be side me were cookin' I was comfortable thanks to my MW1. Thanks for a great product! M.H. Black Canyon City, AZ


THE MW1 COOLS USING WATER ONLY IN DRY CLIMATES:
Last night, I arrived in Mesquite, NV at 7 PM. The temp was 109. Great time to try out the cooler (MW1), I set it in the back seat area, next to the rear passenger window, opened the window about 4 inches and opened the drivers window about an inch, within a couple of minutes the air in the cab started cooling off. It worked great. I climbed into the sleeper about 10 PM and directed the cooler toward me, it again worked great, kept me cool long enough for the outside air to cool down to a comfortable sleeping temp. Right now, I'm in Hesperia, CA. with the temp at 92 and the cooler is keeping me comfortable while I'm sending you this information. Great unit, thanks, B. K. Henderson, CO.
