Specification: Item Type: Automotive Inverter Material: ABS Color: as shown in the picture Input voltage: DC 10.5V-15V (when the battery voltage is lower than 10.5V, the inverter is low voltage protection, when the battery voltage is higher than 15V, the inverter is high voltage protection) Optional output voltage: AC 110V, AC 220V Output frequency: 50Hz for 220V model/60Hz for 110V model. Peak power: 3000 W Rated power: 300W Output Waveform: Modified sine wave. 8 Safety protection function: reverse polarity protection, low input voltage, input high voltage protection, over current protection, short circuit protection, overheating protection, overload protection, internal fuses. Instruction: What size inverter do i need? We recommend that you buy a larger model than you think you'll need (at least 10% to 20% more than the largest load). CARE: -1. This is a modified sine wave inverter, NOT applicable to appliances that run by built-in motor, hair dryers, air conditioners, coffee maker, water pump, induction cooker, refrigerators and microwave ovens etc. Make sure the total power rating of connected devices 400W -2. Tighten the positive () and negative (-) terminals when the car converter is in use -3. If the converter is directly connected to the cigarette lighter. The highest output power must be below 150W. If it is higher than 150W, we strongly recommend using battery clips as the car cigarette lighter may not allow power above 150W. -4. Car converter only suitable for DC12V and car, not applicable for DC 24V and airplane; -5. Please don't leave the inverter in the ON position before starting the car. It is easy to damage the inverter before connecting to the battery. Proper operation must first be connected to the battery, then turn on the inverter switch -6. It is normal for the inverter to get warm during use. For best use results, please place the inverter on a flat surface. The workplace should meet the following criteria: (1) Store in a dry place, do not allow the inverter to come into contact with water or other liquids, keep the inverter away from moisture or water. (2) Cool environment, keep the temperature between 0 degrees Celsius and 40 degrees Celsius. Do not place the inverter near any ventilation openings or other devices. Try to keep the inverter away from direct sunlight. Package List: 1 x Car Inverter 2 x Battery Clamp; 1 x cigarette lighter plug; 1 x Manual Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
