Calculating Portacool's 8 Hour Operational Cost

When we say, "Portacool™ portable evaporative coolers cool the temperature 20° or more all day long for only $1.00 or less per day (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 Portacool model(s), the average cost per day is only about $1.00 (based on an average 8-hour day)!

Here's how to obtain the cost to run your Portacool evaporative cooler all day:


Call your local power company and get the price of a kilowatt hour (or check your last electric company bill).

Example: 0.15739=1 kW hour


Multiply by Portacool average use at .76 kW/hr.

0.15739 X 0.76 = 0.1196


Multiply times 8 hour day (average use)

0.1196 X 8 hrs. = 0.9568


Call your local water company for water cost.

Example: 2.57 = 1000 gallons


Cost of 100 gallons = 0.137

0.257 X 10% = 0.0257


At 5 gallons per hour, multiply for 8 hours.

0.0257 X 40% (40 gallons) = 0.0102



0.9568 + 0.0102 = 0.967 or 97¢

The national average for cities, towns and rural areas in the United States is approximately $1.00 per day!
