Specification: Color: Yellow. Name: Car power inverter 1200W. 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 high voltage protection). Output voltage: AC 110V /220V for your choice. Output frequency is: 50Hz for 220V model /60Hz for 110V model. Type: DC 12V to AC110V, DC 12V to AC 220V. Peaks Power: 1200W. Rated power: 300W. Output waveform: Modified sine wave. Package Size: 6.4x4.4x 2.2 inch. Weight: 0.6 kg. Advantage: 1. [300W Power inverter]: Car power inverter with 2 USB ports and AC outlet. surge power: 1200W, The power inverter comes with free cigarettes lighter and 2pcs battery clips,providing 300watt continuous power, 1200watt peaks power (Please make sure that the total rated power of the connected devices is ≤ 300W). 2. [LED Screen display]: LED Display shows the battery Input voltage, output voltage. Cigarettes lighter cable can supply power for device easily. If the out put power is higher than 200W, please using the Crocodile Clips to a battery. 3. [Fast Charging Dual USB ports ] One AC Outlets and two usb ports can offer 100% fast charging for Mobiles phones, computers, laptop,breast pump, Nebulizer,Razors,medical rescue device,emergency equipment etc,can be as a Emergency Power Supply. 4. [Multi Protection]: Built-in fuses, safe charging design and cooling fan prevents the car power converter from over-heat,saving power and energy.over voltage, overload, over-current, short circuiting, under-voltage, overheating, short circuit protection. 5. [Lightweight design &Top Quality]: Lightweight and compact, ideal for vacations, camping and work trips. It can be plugged into almost any 12V power output vehicle, providing charging opportunities anywhere. CAUTION: 1. This is a modified sine wave inverter,NOT applicable for devices which work by built-in motor, hair dryers,air conditioners, coffee machine,water pump, induction cooker,refrigerators and microwave ovens etc.Make sure that the total rated power of the connected devices is ≤ 300W. 2. Tighten the Positive (+) and Negative (-) terminals when the car converter is in use. 3. If the converter is directly connected with the cigarettes lighter. The highest out put power must be under 150W. If higher than 150W,we strongly recommend you using the Crocodile Clips to a battery ,because car cigarettes lighter might not afford power over 150W. 4. The car converter suitable for DC12V and Car ONLY, not applied for DC 24V and airplane.
