Choosing the Right Inverter Size

To establish which size of inverter is suitable for a particular application, determine the actual wattage an appliance/electronic device will draw while it is operating. Many devices will have the wattage draw stamped on the product. The table below indicates the wattage draw for popular appliances and tools. IMPORTANT: To operate more than one tool/appliance at the same time, add the wattage of each item together to determine the appropriate inverter.
