Instruction:

It can be made from advanced PWM CMOS chip, and can work in the state of ultrasonic sound, which can both in a great extent minish the bulk and weight and make the circuit work without noise. So it is small, light, quiet and convenient. It can protect the electric circuit in a great degree. For example, it can automatically switch off when the voltage of the car battery is low of 10V, so that your car can normally start. And the output of the product is a universal socket, which can be used in many countries. And the newly-added USB output socket can be directly used to charge for MP3 and mobile phone.

• Put the change-over switch to OFF or On .
• Connect the electric cord with the product to the correct terminal, for example, the red wire goes to the positive terminal. Except for the inverter which power is below 120W, because it only has the socket for lighting cigarette.
• The socket for lighting cigarette can just provide the power below 200W. So you must connect the alligator clips with the product to the poles of battery when the output power is above the 200W.
• Be sure of the power of your electric tool is below power rating of the product.
• The green light will be on if the change-over switch is in the state of ON or . The product is in the state of protecting if the red light is on , please turn it off and check it is overloaded or short cut, and the voltage of battery is abnormal or not
