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.
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

CAUTION!
-1.This is a modified sine wave inverter,NOT applicable for devices which work by built-in motor, hair dryers,air conditioners, coffee machine,water pump, induction cooker,refrigerators and microwave ovens etc.Make sure that the total rated power of the connected devices is ≤ 400W
-2.Tighten the Positive (+) and Negative (-) terminals when the car converter is in use
-3.If the converter is directly connected with the cigarette lighter. The highest out put power must be under 150W. If higher than 150W,we strongly recommend you using the Crocodile Clips to a battery ,because car cigarette lighter might not afford power over 150W.
-4.The car converter suitable for DC12V and Car ONLY, not applied for DC 24V and airplane
-5.Please do not leave the inverter in the ON position before car start.It's easy to damage the inverter before connected to the battery.The correct operation is connect to the battery first and then turn on the inverter switch
-6.  It's normal for the inverter to become warm while you are using it.In order to get the best using results, please put the inverter on the flat surface The working
