12-Volt Portable Cooling using Water or Melting Ice to produce cool air will not cool an entire vehicle, camper or boat like an Air Conditioner. Windows cannot be closed like would be possible with an A/C, therefore, with hot fresh air coming in all the time the MightyKool must be set where it will do the most good.

An Astronaut uses a Flex Hose to provide life-giving support, like using our Flex Hose Kit with the windows open in a Vehicle, Camper or Boat. In a humid area without the Flex Hose Kit the MightyKool should be within one foot of where it is needed for maximum cooling while in dryer areas it can be further away.


Customer's Comment shows why the Flex Hose Kit is needed in a vehicle: I use the K2 in my restored 1964 VW. I have positioned the K2 on the front passenger seat and the vents are approximately a foot away from me. Cool air reaches my arm and torso but not my neck and head. Joey V. needs the Flex Hose Kit 2.


Just set the MightyKool out of the way and direct the hoses where needed in Dry or Humid areas. The Two Flex Hoses to contain the maximum cooling possible. Proper Ventilation is also vital, therefore we developed a major help for many uses so check out the Air Intake Housing Kit.


In Humid areas the cool air streaming from the vents of one of our MightyKool Models could be 5 to 15 degrees cooler, which is a major help, however if the cool air travels over One Foot in 90 degree heat it heats up quickly. In dry areas the cool air may come out at 75 in 100 degree heat, however it could increase from 75 to 90 degrees in as little as 2 feet.


Astronauts and Race Car drivers have flex hoses placed where needed. This provides an example of what is possible by using the Flex Hose Kit for your own cooling needs in a vehicle, sleeper, golf cart, aircraft, boat, camper, etc. Each Hose is 2.5 inches in diameter and 7 feet long.
Place a hose in your shirt for welcome relief or under your sheet to get a good nights sleep on a hot night using water only for cooling with no ice needed. After you determine the length hoses you need they may easily be cut off to the correct length.

It is vital to have the cool air vents within one foot of you, not feet away. Take advantage of the cool air with the hose surrounding you for maximum benefit. It is difficult to set the Cooling System within inches of you in a vehicle, therefore the need for the Flex Hose Kit with two 7 Foot Flex Hoses.


The Flex Hose Kit will fit all MightyKool Models to set somewhere out of the way and direct the Hoses where they will do the most good.


An Evaporative Cooler using water only or even adding ice cannot typically reduce the interior temperature of a moving vehicle, therefore the need for the Flex Hoses. In a humid area the Flex Hose Kit is quit often needed for all uses if you want cool air using water only. Set the MightyKool out of the way and place the hoses where needed.

The Owner of this 1970 Porsche 911 choose the MW2 Flex Hose Kit Combo. He thought he would have to purchase a newer Porsche with A/C. He is now able to keep cool in his Classic because of his MightyKool Cooling System with the Flex Hose Kit.


Do not be fooled to think ice will help with evaporative cooling, as this is only a short-lived solution. If money and inconvenience are no problem then you might be willing to use one our "Ice Water" 12-Volt Air Conditioning models that use from 12 to 20 pounds of ice PER HOUR.


Normally using Evaporative Cooling you do not need the Flex Hose Kit in a Camper, Boat, Tent, etc., just a Vehicle. In a humid are you want to consider the Flex Hose Kit to take advantage of the 10 to 15 degree cooler air that you will experience using water only. Back to the Top


With simple installation either the 2 or 4 Flex Hose Kit allows you to set the Cooling System out of the way directing the Cool Air up to seven feet where you need it the most. Strongly consider the Kit if you must set your Cooling System farther than a foot or so away from your needs in extreme heat especially in a Vehicle or Aircraft.

The Flex Hose Kit FH2 (left above) contains everything needed for two hoses and the FH4 Kit (left below) contains everything needed for four Cool Air Vent hoses when you use a MightyKool. If you have a MightyKool Model with four Cool Air Vents (like the M400 or MK4) you would only use the front two and close the ones on the side for Flex Hose operations.

A Customer sent in this idea; I fashioned two hooks to hold the hoses anywhere in the car using some utility velcro straps and the cut off ends from a worn out bungee cord.


One reason you might want the Flex Hose Kit is when you are trying to cool two areas some distance from each other like in a Pop Up camper. For Pets in kennels or cages the Flex Hose Kit is a must. Also for pets check out the Air Intake Housing Kit.

First step is to simply remove the two Chrome Cool Air Vents from your MightyKool, install the Hose Adapters in their place and then position the Cooling System in an area out of the way.


Next secure the Flex Hose to the Hose Adapters that replaced the cool air vents, decide where you need the cool air then determine the length of Flex Hose needed. Cut off the excess hose placing the Chrome Cool Air Vents you removed into the end of each Hose. Secure all hoses with the wire ties and you are set to cool.


If you use the Flex Hose Kit the cool air is contained in the hose and only looses one degree per foot in 100-degree ambient air. For our example the 75-degree cool air would be 77-degrees in two feet, 79-degrees in four feet, etc.


Another factor is the Air Velocity effect using a Flex Two Hose system. The normal Feet Per Minute (FPM) velocity from each front outlet vent averages around 1,900 FPM per side on the MightyKool models. There is no loss in velocity using a five feet Flex Hose and the velocity using seven feet only drops about 7%.


Using the Flex Four Hose system yields about 1,300 FPM from each of the four hoses. Compare that with the total of 1,900 FPM coming from the two front vents. Granted that the four hoses will not have the velocity of the two hose system, however 1,300 FPM is plenty of velocity when you direct the cool air properly like you do in a Commercial Airliner.


The Flex Hose Kit Model FH2 contains two hose Adapters that will replace two Chrome Air Vents so that the hose can be attached to the front of the MightyKool. There are two 7-foot flex hoses with sufficient black plastic wire ties to help hold the flex hose where needed. The Chrome Air Vents will attach inside the flex hose end that has been cut to the desired length. (No shipping/handling charge when ordering a new MightyKool model at the same time).


The Flex Hose Kit Model FH4 contains two hose Adapters that will replace two Chrome Air Vents so that the hoses may be attached to the front of the MightyKool. There are two 7-foot hoses, two 3-foot hoses, two one foot hoses and sufficient black plastic wire ties to help hold the flex hose where needed. There are two "Y" hose connectors to direct the air into the four hoses plus the two hoses going to the Cooling System. Also included are four new North Star Chrome Air Vents with four adapters to connect to the ends of the hoses. The original Chrome Air Vents are not suitable for the Flex Hose Kit FH4. (No shipping/handling charge when ordering a new MightyKool model at the same time).
