4000W Voltage Converter 12V 220V/110V Led Ac Car Power Inverter Converter Charger Adapter Inverter Dual Usb Transformer Modified Sine Wave

1. Dual LCD digital display allows you to maintain the output voltage and battery voltage value at any time.

• 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. 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 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.
