4000W 12V to 220V - 110V Dual USB LED Car Power Converter Modified Wave Inverter, Black, 12V to 220V

Features:1.The dual LCD digital display allows you to monitor both the output voltage and battery voltage at all times.2.Fault prompt function.In addition to various audible prompts, faults can also be displayed more intuitively on the screen (e.g., battery undervoltage, battery overvoltage, overload, high operating temperature, output short circuit, etc.).3.The overload delay shutdown function has been added to the product to address the critical issue of inverter protection during the startup of sensitive electrical devices.4.For the low-power, non-professional user market, the positive and negative polarity reverse polarity protection function has been enhanced.5. Intelligent temperature-controlled oil sealing fan.When the inverter is operating, it can function at a specific temperature, which is more energy-efficient and quieter.6.Digital MCU control, waveform output type, more precise frequency, precise output voltage, fast response of the protection circuit.Descriptions:1. This is an inverter, using STM chip technology and intelligent protection types, high reliability.2.
