How To Determine What Size of Inverter to Use

 
All inverters are rated in watts and most electrical appliances have a wattage rating.
Use our online Calculator Tool to ensure the wattage rating of the largest load is within the wattage rating of the inverter you select. 
Pure sine wave inverters can run any of the modified sine wave inverter loads, as long as they meet the same operating and surge requirements of the load.  Pure sine is ideal for running loads with sensitive electronics or tools. Learn more

Wattage Used by Mobile Appliances & Tools

Operating wattage may not be exact for all applications. Please review individual product specification for actual wattage requirements. Wattage rating can be calculated by: Volts (120) x Amps.
