Feature:1. DC12V TO 220V: 300W power inverter provides 300W continuous DC to AC power, converting 12V DC to 220V AC via 2 AC power outlets and 2 USB fast charging ports (3A 2.4A).2. TEMPERATURE CONTROL TECHNOLOGY: New temperature control technology is used. When the internal temperature of the inverter reaches 113 45, the fan starts to dissipate heat, which is more energy saving and fuel saving.3. BUILT IN FUSE: Car converter has a built in fuse. In case of overheating, charging under voltage over voltage, short circuit, overload, overcharge, etc. The power can be automatically cut off to protect your equipment.4. ALUMINUM HOUSING: 300W car converter is made of aluminum housing and has been drop and crash tested. Cigarette lighter plug allows the power inverter to be plugged into almost any vehicle.5. SCOPE OF APPLICATION: 300W car power inverter is perfect for your phone, tablet, computer, MP3 player, and other devices. Ideal for vacations, work trips and camping.Specification:Item Type: 300W Car Power InverterMaterial: MetalInput: DC12VOutput: AC220VContinuous Output Power: 300WPeak Power: 600WUSB Output: 1 x 5.0V-2.4A, 1 x 3.0AProtection Function: Overload, Overvoltage, Overheat, Low Voltage Protection.Package List:1 x300W Car Power Inverter1 x Instruction Book
