Estimated Watts

When selecting a power inverter from Inverters R Us, please make sure it has enough power for your appliance. Just add together the watts for each item you may want to run at the same time. Keep in mind to also add about 15% to the total wattage to ensure you will have enough power to meet your needs.

The estimated watts for the appliances below are estimates; please check your manual or the appliance itself for the actual wattage required. Doing this will ensure you select the correct inverter the first time.

Please use this easy formula to determine the correct size DC to AC power inverter if you only have Amps:

AMPS x 120 = Watts

Example: 15 Amp Cooling Unit X 120 = 1800 Watts
