Tellunow 500W Power Inverter DC 12V to AC 220V 230V 240V Transformer Car Converter With 4.2A Dual Usb And 2 Ac Outlets For s, , Laptop,Nebulizer

NOTE:

This product belongs to repair sine wave inverter, it is suitable for stable current output, such as charging with electric appliance, and emergency electricity.
Due to the perceptual load at the moment of sw power supply or disconnect the power supply (starting current), will produce counter electromotive 
force voltage, such as refrigerator, fan, etc., the ac voltage is far greater than the peak load for electric equipment can withstand voltage, it is easy to cause
  the instantaneous overload of motor inverter, affect the service life of the inverter.Therefore, this kind of electrical appliances need higher power supply waveform.

Specifications:

Size:500W
Power (2 AC Outlets): 500W Rated, 1000W peak
Output wave: pure sine wave
Nominal input voltage:12VDC
Nominal output voltage: 220-240VDV
Use method:

1. The positive and negative poles of the ring wire are connected to the inverter
2. must tighten the terminal
3. the positive and negative ring line is properly connected to the battery
4. connect the device
5. open the inverter switch
Precautions:

The inverter switch must be switched off before connecting the inverter. The inverter voltage must be the same as the battery voltage, the 
inverter voltage is DC12V, then the battery voltage must also be 12V, otherwise the inverter will not work or be damaged.
