Yes I have two BIG
windows on the sides and one between the cab ..... from the website.....
I called and they said the smallest one - the Might Kool will blow 75 degree air... the bigger units - that use an ice chest and ice will blow 65 degree air!
One gallon (3. 75 liters) will last around three hours in the daytime and seven to eight hours during the night time in our small portable evaporative coolers. Use any clean domestic or lake Water.
--------------------------------------------------------------------------------
A good deep-cycle battery (105 amp hour or larger) lasts from 8 to 17 hours on low and medium without charging when using all models except the MightyKool Series.
--------------------------------------------------------------------------------
The MightyKool Model MW1 will last from 50 to 80 hours and the MightyKool Models M200 & M300 will last from 25 to 35 hours on a fully charged 105 amp hour Deep Cycle Battery.
Also from the website on the M200 Ice Model... ...
How do the Ice Coolers Work?
--------------------------------------------------------------------------------
This Self-Contained Air-Conditioning System does not require Venting when using ice & is Equiped with Energy Efficient Brushless Double Ball Bearing Motors. These Motors operate on 12-Volts or 110-Volts using an Optional AC/DC Convertor.
Use Ice & Water to produce Air Conditioned Comfort in Humid or for colder air in Dry Climates.
You may use Water only or Water & reusable ice packs when the Heat is not too Severe in either Dry or Humid Climates.
"I recently purchased the Swampy M200 Ice model for use in my Cessna 182. I spoke to you on the phone and told you I would let you know how it works. I am very pleased with the product. I use the rear seat belt to hold it in. That permits the air to be blown on both the passenger and the pilot. The units works quite well, and I do get anywhere from 30 minutes to an hour of use. I typically use it taxiing and until I reach altitude. Then I pull the plug. On reaching pattern altitude I plug it back in, and I usually have plenty of cooling left to make it to the hanger. All my pilot friends are tickeled we don\'t have to sweat while waiting for takeoff. Thanks for the recommendation and for a great product. I recommend it to all my pilot buddies. " B. W.

"Hi there, just wanted to say I received my M200 today. I am using it primarily indoors in a room where there is air conditioning, but because a computer is running all day long, it gets too warm. I didn't want to use a portable AC unit because it would cost a lot more than running a 40 watt appliance. The evaporative cooling works great, even though I live in Alabama, since the humidity inside is generally around 40 to 45%. I have owned an evaporative cooler before, and after feeling the air from the M200, it is questionable whether the other cooler ever worked at all. I measured 78 degree air going in and coming out at 66 degrees. I put my ice packs in their and I was amazed that the air dropped another or 8 or 9 degrees. Thank you for such a fine product. It is small, attractive, and really does make my computer room much more comfortable. I am really going to enjoy this cooler. " S. S. Oxford, AL. March 2006
The MightyKool Model M200 provides air conditioned comfort without opening windows or venting the heat outside when using ice. This is a Versatile Self-Contained, Fully Assembled, Cooling System with a base that is exposed by sliding the Cooling System forward so ice, water or reusable ice packs may be placed inside the base. The M200 operates on most any power that you choose; 12-Volts, 110-Volts or Solar. In otherwords keep cool while while Camping, Boating, Traveling or in your Bedroom or Work area at Home. You can add enough ice to the ice container of the M200 to have air conditioned comfort for as long as one to one and a half hours. If you are using water only the M200 will operate for 4 to 10 hours without refilling. It does not damage anything if it runs out of water.
Using powerful Brushless Double Ball Bearing Motors the M200 merely sips power while streaming cool crisp air when & where you need it. This Cooling System has the capacity to produce over 220 cubic feet per minute (cfm) at a velocity of 3,000 feet per minute with a noise level of 59 dBA on high speed which is about like road noise driving 60 M. P. H in a typical vehicle. The dBA is slightly higher than our other Swampy models because the motors are operating freely at a higher more efficient R. P. M.
Use on 12-Volts and you will have cool crisp air streaming at you for 25 to 30 hours without recharging a typical 105 amp hour Deep Cycle Battery you may choose to purchase. Of course if you are using it while running your engine you need not be bothered about the amperage draw as it uses no more energy than your vehicle tail light bulbs. This combination Air Conditioner - Evaporative Cooler contains the MightyKool Evaporative Cooling System (ECS). The Air Contitioner portion uses the heat exhange core made famous by our Swampy "Ice" Models. The MightyKool ECS has proven to be more efficient than the typical evaporative cooler in humid climates because of the design of the Evaporative System itself. Therefore, when the heat is not too severe you may use water only or water cooled by reusable "blue" ice. If you wish you may click on Testimonials regarding the standard MightyKool in Humid Areas.
This Model will also operate efficiently on your Solar System, using only 41 watts (less than 3. 5 amps) on 12-volts! The M200 incorporates the Custom Evaporative Pad System our standard MightyKool Model MW1 is so famous for pioneering. The MightyKool M200 on high speed moves about the same amount of air flow as our very popular Swampy Model S154 does on Medium Speed at a fraction of the energy use. Plus the air is moving in Three Directions at the same time, or you may concentrate the air in any of the three directions by closing one or more of the four cool air outlet vents!
