How long will an AceOn PES run your appliances?
Choose a unit, then pick an appliance or type in its wattage to see how many hours it will run from one full charge. Use the table further down to compare all three units side by side.
The figures assume 85% of each unit’s rated energy is usable, to allow for inverter and conversion losses. Fridges and freezers switch on and off, so in practice they run two to three times longer than the figure shown.
Have a different battery, or a device that is not listed? Use the general battery run-time calculator.

How long will the PES 2000W run your appliances?
Pick an appliance or type in its wattage. 220V AC pure sine wave inverter — runs mains appliances up to 2000W continuous.
Watts are printed on the appliance label or in its manual. If the label only shows volts and amps, watts = volts × amps.
43" LED TV, from one full charge
Figures use 85% of the rated 1,997Wh (1,697Wh usable) to allow for inverter and conversion losses. Actual run time varies with temperature, battery age and how the appliance is used. Keep the continuous load below 2000W; motors and compressors need a short surge to start.
Which unit do you need?
Run time for one appliance at a time, from a full charge. “Not suitable” means the appliance draws more than that unit’s continuous output.
