Automotive inverter power can change the 12 V DC provided by car into 220 V AC used usually, which is widely used in various electrical devices, to choose inverter, you should pay attention to the following questions:

1. Protection is very important: the flow, overload, high pressure, high temperature, short circuit, under-voltage protection, will not cause damage to external electrical equipment and vehicle its own, built-in electronic fuses will be safer.

2. Conversion efficiency: this is a very important indicator of inverter, the higher the efficiency of inverter, the longer time to use battery, the smaller the inverter fever. Generally it should be more than 90 percent. With microcomputer chip control technology, products' power conversion more than 90 percent, real-time voltage and current overload microcomputer automatic adjustment control, and intelligent control.

3. Output value and output frequency accuracy and stability, load dynamic stability, load adaptability. The actual power output will not be less than the maximum power and power marked. (Such as: input voltage range DC11V - 15V output voltage range AC210V --- 230V maximum power of 600 W rated power 350 W)

4. Variety of design protection circuit, overload, short-circuit the flow of high pressure circumstances, such as under-voltage high temperature can effectively carry out their own protection and use of electrical appliances and automotive protection, equipment and vehicles will not cause harm. When the voltage is lower than 10.5 V, will automatically stop working to ensure that the battery power cushion.

5. It is also important that the output jack design is the best use of omniment plugs, suitable for all kinds of plugs.

6. Small in size, noise and housing materials. For the aluminum shell texture, with good heat dissipation, there is a good after-sales service.

7. Electrical power greater than 200 W, must use battery clip to get power directly from the battery: Automotive Cigarette Lighter socket only by about 10 A current, so the high-power inverter must have another battery clip line to get power directly from battery. There are a number of manufacturers in order to save costs, even 300 W products are not with battery clip lines.
