How Much Does a Portable Air Conditioner Cost to Run?
Estimate the cost of running a portable air conditioner from its wattage, hours of use, and your electricity price.
Cost estimate

Estimated energy use0 kWh/day
Estimated monthly energy0 kWh/month
Cost = watts ÷ 1,000 × hours used × electricity price.
Example
How the starting estimate works
At 1,200 watts for 8 hours per day, the starting example uses 9.6 kWh per day if the compressor were drawing that power continuously.
Real-world use
Cooling equipment cycles with the room load.
A portable AC may cycle its compressor rather than draw full rated power every minute. Room size, outdoor temperature, thermostat setting, and hose configuration all affect actual consumption.
