IMPORTANT: Before operating medical equipment, such as a nebulizer, check with the medical equipment manufacturer. Majority of medical equipment is not compatible with modified sine waves.
Please check with the appliance manufacturer to see if it is compatible with a modified sine wave output from an inverter. This is especially important for computers and cordless power tools. Equipment not made to support a modified sine wave from an inverter or generator may be damaged if connected to the inverter.
Check the appliance rating label, it should be listed in Amps or Watts. If rating is listed in amps, multiply the amps by 120 volts. The answer will be the watts that is required. This number should be lower than the continuous wattage rating of the inverter.
If the appliance has a motor or picture tube, start-up surge must also be considered. Start-up surge is extra watts the appliance requires to turn on or "start-up". The start-up surge can be as high as 10 times its rated watts. An example of this would be a skill saw. The lights in the house can dim when the saw is first turned on. This dimming is the start-up surge. With the start-up surge in mind, select an inverter with a continuous wattage rating equal to or larger than the start-up surge.
Microwave cooking power is not the power required to operate the microwave. It generally requires twice the cooking power. Check the appliance rating label, it should be listed in Amps or Watts. If rating is listed in amps, multiply the amps by 120 volts. The answer will be the watts required. This number should be lower than the continuous wattage rating of the inverter.
The inverter may not power some newer TVs. Newer TV's power on/off switches control internal software (computer) components which do not support jump starting.
