Please NOTE
The  inverter  wave uses a load such as a motor, which will emit a relatively noisy humming or whistling sound, which will burn out the motor coil, and may also damage the inverter, and some precision electrical appliances cannot be used, such as computers and printers and more
It cannot be used for inductive loads, such as electrical appliances such as motors and transformers,Fan, Kettle and Grinder

Electrical appliances available：
It can be used in mobile phones, notebook computers, TV sets, video cameras, CD players, various chargers, car refrigerators, game consoles, DVD players, and power tools.

Please note:
When you use inverter, please use it according to the wattage of continuous power
