Characteristics :1. Dual LCD digital display allows you to maintain the output voltage and battery voltage value at any time.2. Default prompt function. In addition to the different sound prompts, it can also be displayed more intuitively from the display screen (for example, battery undervoltage, battery overvoltage, overload, high operating temperature, output short circuit, etc.).3. Overload delay closing function is added in the product to solve the sensitive problem of inverter protection when the soluble electrical appliance is started.4. The market of non-professional small power users has increased the protection function of positive and negative pole feedback.5. Intelligent temperature control oil sealing fan. When the inverter is working, it can work at a certain temperature, which is more energy efficient and quiet.6. Digital MCU control, dande type output wave, more accurate frequency, accurate output voltage, fast response of protection circuit. In cars, steamboats, mobile post and telecommunications, public safety, emergencies and other areas. -15.5voutput voltage: 110 V/220 V (optional) output voltage range: 110 V 10 percent /220 V 10 percent frequency: 50 Hz / 60 Hz 9.5vhigh voltage protection: with maximum protection voltage of 15.5voverload protection: yesshort circuit protection in output: yespositive and negative reverse connection protection: yesoutput rating 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 / 1.43lbPackage included :1 x inverter 1 x crocodile toner 1 x cigarette lighternote :1.
