1The intelligent cooling fan will automatically rotate at different speeds according to the power load and temperature, to help reduce the noise of the fan, and the highspeed cooling fan can also prevent the inverter from overheating. 2DC12V power inverter is widely applicable, perfectly suitable for cars, motorcycles, s, emergency work, outdoor work, home emergency and other situations. 3The power converter is equipped with a single universal cigarette lighter plug, which makes the power inverter can be plugged into almost all vehicles. 4The modified sine wave inverter has safe charging design can prevent overheating, undercharging, low voltage, over voltage, over current, short circuit and overload. 5The power inverter has an aluminummagnesium alloy shell. 6The converter is super small and light, and very convenient to carry, and the converter is obviously an ideal choice for vacations, business trips and camping. Item Type: PowerInverter Material: AluminumMagnesium Alloy + ABS Continuous Power: 150W Peak Power: 300WInput Voltage: DC 12V USB Output: DC 5V(0.5A/1A/2.1A) Output Waveform: Modified Sine Wave Size: Approx. 95x64x38mm/3.7x2.5x1.5in Application: Widely used in home theaters, electric grinding wheels, electric tools, sewing machines, DVDs, forVCDs, computers, TVs, washing machines, range hoods, video recorders, massagers, fans, lighting, etc. and other household appliances. Various electrical appliances can be used in the car by connecting household appliances to the output end of the power converter. The electrical appliances that can be used are: mobile phones, laptops, digital cameras, cameras, lights, electric shavers, CD players, game consoles, handheld computers, power tools, car refrigerators, and various travel, camping, and medical emergency appliances and so on. How to Use: 1. The DC voltage must be consistent. Each inverter has a DC voltage value, such as 12V. The battery voltage must be selected to be consistent with the inverter's DC input voltage. 2. The output power of the inverter must be greater than the power used by the appliance, especially for appliances with high power at startup 3. It should be placed in a ventilated and dry place, beware of rain, and be more than 20cm away from surrounding objects, away from flammable and explosive materials, and do not place or cover other objects on the machine. The use environment temperature is not more than 40. . 4. Charging and inverter cannot be carried out at the same time. That is, do not insert the charging plug into the electrical circuit of the inverter output during inverter. 5. The interval between two startups is not less than 5 seconds (cut off the input power). 6. Please wipe with a dry cloth or anti-static cloth to keep the machine tidy. 7. Before connecting the input and output of the machine, please ground the casing of the machine correctly. 8. To avoid accidents, it is strictly forbidden for users to open the case for operation and use. 9. When you suspect that the machine is malfunctioning, please do not continue to operate and use it. 10. When connecting the battery, make sure that there are no other metal objects on your hands to avoid short circuit of the battery and burn the human body. 11.
