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 different sound prompts, it can also be displayed more intuitively from the display screen (e.g. battery undervoltage, battery overvoltage, overload, high operating temperature, short- output circuit, etc.).3. The overload delay closing function is added in the product to solve the sensitive problem of protecting the inverter when the soluble electrical appliance is started.4. The small power non-professional user market has increased the positive and negative pole return protection function.5. Intelligent temperature control oil seal fan. When the inverter is working, it can operate at a certain temperature, which is more energy efficient and quieter.6. Digital MCU control, output wave type, more accurate frequency, accurate output voltage, fast response of protection circuit. in cars, steamships, mobile posts and telecommunications, public safety, emergencies and other fields. -15.5V Output voltage110V/220V (optional) Output voltage range: 110V 10% / 220V 10% Frequency: 50Hz/609.5Hz HzHigh voltage protection: with a maximum protection voltage of 15.5VOverload protection: YesProtection against output short circuits: YesReverse connection protection of positive and negative polesYes Output voltage stabilization : Yes Buzzer protection : Yes USB interface : 2.1A x 2 Input terminal connection mode : terminal Output interface : international general socket Product size (mm): 161mm/6.28in x 112mm/4.37in x 56mm/2.18in Package information: Package Size :187x100x145mm/7.29x3.9x5.66inPackage Weight:650g/1.43lbGeneral Box PackagePackage Included:1 x Power Inverter1 x Alligator Clip1 x Cigarette LighterNote: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.
