Features: 1. Dual LCD digital display allows you to maintain the output voltage and battery voltage value at any time. 2. Fault prompt function. In addition to various sound prompts, it can also be displayed more intuitively from the display screen (e.g., battery undervoltage, battery overvoltage, overload, high operating temperature, output short circuit, etc.). 3. The overload delay closing function is added to the product to solve the sensitive problem of inverter protection when the soluble electrical appliance is started. 4. The positive and negative pole reverse protection function has been added for the small power non-professional user market. 5. Intelligent temperature control oil-sealed fan. When the inverter is working, it can operate at a certain temperature, which is more energy-saving and quieter. 6. Digital MCU control, output waveform type, more accurate frequency, accurate output voltage, fast response of protection circuit. in cars, steamships, mobile posts and telecommunications, public security, emergency and other fields. -15.5VOutput voltage: 110V/220V (optional)Output voltage range: 110V 10% / 220V 10%Frequency: 50Hz/60Hz of 9.5VHigh voltage protection: with a maximum protection voltage of 15.5VOverload protection: YesOutput short circuit protection: YesReverse connection protection of positive and negative poles: YesOutput voltage stabilization: YesBuzzer protection: YesUSB interface: 2.1A x 2Input terminal connection mode: terminalOutput interface: international general socketProduct size (mm):161mm/6.28in x 112mm/4.37in x 56mm/2.18inPackage information:Package Size:187x100x145mm/7.29 x3.9x5.66inPackage weight: 650g / 1.43lb General Box Package Package Included: 1 x Power Inverter 1 x Crocodile Clip 1 x Cigarette Lighter Note: 1.Please allow 1-2mm errors due to manual measurement. 2.Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same.
