World-renowned Portable 12-Volt Cooling Systems chilled by our exclusive Smart Cooling Filter Pad. The Smart Pad is at the Heart of the MightyKool Models Cooling Superiority using Water only without Ice and fully 5 degrees cooler than any other Portable Evaporative Cooler using a Pump in either humid or dry climates. Click here Information about the Smart Pad


The MightyKool Model MW1, MW2 or the WIN3 are the answer for low 12-volt energy usage plus the Coolest Air from any Portable Evaporative Cooling System for your Camper, Boat, or Sleeper in Humid as well as Dry climates. A float has been incorporated into the MW1 for extended cooling times using the standard Water Kit. Proper Ventilation is important when using any evaporative cooler.


You will appreciate the small versatile size of the MW2 unless you think something must be large to be worth the money! Our engineers designed this System to produce more cool air than any other comparable system that is up to five times larger. Engineers didn't design the Jet Engine to be larger than Piston Engines, just more powerful. Dimensions


This situation is drastically different if you need cooling in a Vehicle while driving than using cooling for sleepers, boats or campers not moving. In the case of driving in a vehicle you might consider the MW2 or WIN3 and the Flex Hose Kit, as it is difficult to find a spot to set the MW1 close enough to you, without loosing the coolest air. When using the Flex Hose Kit the WIN3 & MW2 do have 15 to 20% more cooling velocity. Just plug in the The 10 foot power cord and add water. The MW1, MW2 & WIN3 are real favorites for off the grid Solar use.

The Smart Cooling Filter Pad is at the Heart
of the MightyKool Superior Cooling. Ice may be added, however it is not needed because of the unique Smart Pad, as adding ice only cools slightly better for a very few minutes before it melts. The easy to see Site Glass with the Floating Ball is integrated into all three MightyKool Models using water only which makes it very easy to see the water level.

Our Custom Cooling Filter Pads are "Smart" Pads, as they automatically regulate the water needed depending on temperature, humidity and dew point. Pouring water on the Smart Pad is never needed, as it automatically wicks what it needs at all times. If the air is Dry the Smart Pad uses more water and if the air is Humid it uses less water. Also Incorporated into our Smart Cooling Filter Pads are Anti-Allergenic plus include a Mold-Fighting Agent.

A normal evaporative cooler has a pump that puts the same amount of water into a different type pad regardless of temperature, humidity or dew point, therefore normally distributes either too much water or not enough. That is the reason that our MightyKool products produce several degree cooler air than any portable Evaporative Cooler using a Pump. You may use either hot or cold water, as the results will be the same within minutes because of the unique Smart Pad System of the MightyKool MW1, MW2 & WIN3.


This unique Smart Pad should be changed every several hundred hours, so that you may continue to enjoy the Cool Filtered Air experienced when the MW1, MW2 or WIN3 were new. Of course, we have some Customers use their Smart Pad for well over 500 hours before changing and others only change every 3 to 4 years, however they are not getting the freshest filtered Coolest air possible in either case.
The Internal water container of the MW1 & MW2 hold from one to three hours of cooling, however it also has an Automatic Filling System through a float. Even if it is quite humid continue to use water, as there will always be cooler air than a fan using less energy than a fan, as long as you provide good proper ventilation.

The float may be connected to an external water source like our Water Kit (left) if you do not want to add water every one to three hours. To top this off you can also operate the MW1 in your home on 110-volts with the optional AC/DC Converter. You may wish to consider looking at these inexpensive Options as Shipping & Handling is included Free for single options with your original order.

WINTER USE: We have people use them all winter long to help increase humidity in an enclosed environment, which lowers the heating bills and aids comfort, just like any humidifier. Back to the Top


Using powerful Twin Brushless Double Ball Bearing Motors this Model merely sips power while streaming cool crisp air where & when you need it. The Twin Motors have the capacity to produce over 200 cubic feet per minute (cfm) at a velocity of 2,000 feet per minute with a noise level of 59 dBA on high speed, which is the same as typical human voice or vehicle at highway speeds dBA.

If you can visit while riding in a commercial jet aircraft, you can easily visit while enjoying the MightyKool's cool air or let it hum you to sleep. You can adjust the level of power you prefer with the three-speed switch. The WIN3 does have an advantage with the dBA level by using the Air Intake Housing Kit, which is used to simplifiy receiving Proper Ventilation.


I received the Swampy MW1 on Wednesday. Your communication and shipping on my order were accurate and very prompt. The MW1 arrived well labeled and packed. The MW1 is easy to use. The fan is quiet and really moves a lot of air! Initial testing at 10% humidity and 81 degree ambient temperature produced an output vent temperature of 62 degrees. With the fan set on medium speed this was more than adequate to cool the occupants of our conversion van. The MW1 is very well constructed. I congratulate you on an excellent design carried through with quality parts and an attention to detail. For those who need a compact 12 volt "swamp cooler" I can recommend the MW1. Thank You, L.J. Morristown, AZ (They travel extensively & use the MW1 primarily for camping including sleeping in their Van)


"Dear Swampy, We just wanted to drop you a line to tell you how well our Mightykool (MW1) worked for us in our trailer on the Playa at Black Rock City. We run off of solar so this was a great way to cool off and be able to nap during the 90 degree days. Thanks," C. and C. Jackson, WY


"I finally got a chance to use the Swampy MW1 over the 4th of July weekend in 90-95 degree weather. This thing RULES! It kept my whole camper cool on a medium setting and was turned down to low at night. I am so impressed with the way it performed, it was worth every dollar! Thanks again for all your help!" C. E. Palisade, CO.


I received my Mighty Cool and it's a pretty awesome little contraption. I have only used it twice now for short periods of time, but so far am very pleased. I am excited to use it on a weekend camping trip coming up in my trailer and later on at Burning Man. Thanks!! A. M. Grand Junction, CO.

Specifications

What are the Dimensions, Amperage Draw and Water Capacity?

One gallon (3.75 liters) of water will last around two to three hours in the daytime and four to five hours during the night when used for evaporative cooling in dry desert climates. The "Ice Water" models typically use from 10 pounds (4.5 kilograms) to 20 pounds (9.0 kilograms) of ice Per Hour, depending on the ambient temperature and day or night operation.

A 105 Deep Cycle battery, "not being charged", allow the MW1, WIN3 & MW2 to operate for 50 to 80 hours and the "Ice Water" models like the MK3, MK4, MAC & M400 will operate for 25 to 35 hours before the battery needs charging. The S154 Model will operate about 8 hours before the battery would need charging, as it uses more energy.
Dimensions do not include the 1 inch (2.54 C.) Handle & 3/4 inch (1.9 C.) Switch

 Evaporative Cooler Models MW1, MW2 & the WIN3 use Water only, however ice could be added if you wish.
The M400, MK3, MK4, MAC, & MG4 Provide; Dual Air Conditioning using Ice or Water
All "Ice Water" Systems automatically dispose of the excess condensation collected
