Notes:
- The wattages given above are only estimates. The actual wattage required for your appliances may differ from those listed. Check the nameplate usually found on the rear or underside of appliances to determine the actual wattage required.
- Appliances and tools with induction motors (marked * in tables) may require between 3 to 7 times the listed wattage when starting. The start-up load of the appliance or tool determines whether an inverter has the capability to power it. Be sure to check the specific wattage requirements and operating instructions for appliances/tools before use.
