Calculating Port-A-Cool's 8 Hour Operational Cost

When we say, "Port-A-Cool cools the temperature 20° or more all day long for only 50¢ (about 1/10th the cost of standard air-conditioning)," we really mean it!  Based on a survey of 22 cities and towns across the United States and hundreds of our customers telling us the hours they most used their Port-A-Cool unit(s), the average cost per day is only 50¢!

Here's how to obtain the cost to run your Port-A-Cool all day:

1. Call your local power company and get the price of a kilowatt hour (or check your last electric company bill). Example: 0.05867=1 kW hour
2. Multiply by Port-A-Cool use at .76 kW/hr. 0.05867 X 0.76 = 0.0445
3. Multiply times 8 hour day (average use) 0.0445 X 8 hrs. = 0.3560
4. Call your local water company for water cost. Example: 98¢ = 1000 gallons
5. Cost of 100 gallons = 0.0980 .98 X 10% = 0.0980
6. At 5 gallons per hour, multiply for 8 hours. 0.0980 X 40% (40 gallons) = 0.0392
7. Total. 0.3560 + 0.0392 = 0.3952 or 39¢

This example is the cost to operate a 36" Port-A-Cool in Center, Texas.  The cost in San Diego, California is 53¢ per day.  The national average for 22 cities and towns in the United States is exactly 50¢ per day.
