Plug-and-play
1.Insert the power inverter into automobile's cigarette jacket. Please check the losse and tight degree between the car's cigarette socket and the outlet while inserting, if it is too loose, please splay the two slices and insert them to the electric outlet of the cigarette jacket.
2.Please confirm whether the power inverter's indicator is on or not

3.Insert the power inverter's plug of the electric appliances to power inverter's outlet.
The fuse replacement:Screw the cigarette socket's outlet on negative direction and change the new fuse.

1.Before pulling out the switch of the using electric appliances from the power inverter,please confirm whether the switch of the electric appliances have already been off or not firstly,then,you can pull out the power supply plug and draw the power inverter out.
2.Please use the same and the eligible style and specification fuse to replace the burn-out fuse, otherwise will result in the fuse and the wire too hot and being on fire.
3.Please clear up the dirty materials of the outlet in case of the transformer is too hot to be used.
4.Please keep and using the power inverter according to the usage mannual.

Answer:Mainly divided into two types: one is the pure sine wave power inverter, the other is the square wave power inverter.Pure  sine wave is the best alternating current in our daily life,which will not result in the electromagnetism pollution.Comparing with the pure sine wave, the square sine wave form have several disadvantages: firstly, the output alternating current quality of the square wave is relative poor,because the anode extremum and the negative extremum usually exist at the same time, which will lead to the power inverter unsteady. Secondly,the load ability of the square wave is just 40-60% of the rated power,and can not get with the inductive load together(see see diagram).All in one word, the pure sine wave form is much superior,however, it is too expensive;and the character of the square wave form is not fit for the electric apparatus.Therefore, the modified sine wave is the best choice for most power inverter, which is known for its low noise,high efficiency and the most competitive selling price.The wave format for the modified sine wave please see next diagram:

Answer:Popularly,the strong power electric apparatus such as the electric motor, compressor,relay,fluorescent lamp etc..While starting this kind of product,the electric current will be about 3-7 times as the normal current at the first moment.For example,the normal power for an operating refregirator is about 150w,and the starting power will reach to 1000w or its above. Additionally,because the sensitive faculty load is connecting the power supply to break to open the power supply perhaps for an instant, will produce the anti-electromotive force electric voltage,and the peak voltage of the electric voltage is much larger than the capability the power inverter can bear,which will affect the life of the elecronic machine.Therefore,this kind of electric appliances has higher request to the supplied wave form.

Answer:The pure sine wave also has many different styles,and we just discuss the trapezoid wave only here, which can be supplied by most high frequency power inverter.This kind of pure sine wave power inverter can be used  in the notebook computer, television, stereo set, camera, digital camera,refrigerator, printer, various charger, PDA, game machine, video-disc,DVD and so on.

Answer:Inputing the power inverter from car's cigarette socket,  which can drive the machine more than 100 watte. Basing on our customer's feedback, power inverter will be automative alarming while connecting with the power inverter for several minutes.As we know, the power inverter for the P4 notebook computer is about 90W,because some cars used with the uneligible lead and cigarette socket,which result in the power inverter can not function normally. To solve this kind of problem and to ensure the power inverter in normal and safety usage,we hope the users to change the poor quality lead to the eligible lead and change the cigarette jacket under some conditions.

Answer:This is normal, If you want to get the correct digital, please used with the 'true value' common multimeter to measure the alternate current of the pure sine wave power inverter.

Answer: Of course.When the power of the using electric apparatus is over 250W, the general electric cell can provide the power to it for 60-120minutes under the condition of closing the starter, if only used with the 50-60W notebook computer,the usage time will be much longer. Our modified sine wave power inverter have set built-in alarm protection and under voltage shutdown protection,when the voltage is lower than 10V for a long time,the output voltage will be shut off and will be automative in alarming.Therefore,you can use our products when shutting off the automobile.
