[NEVER USED] 4000w 12v 220v LED AC car inverter charger adapter converter dual USB transformer sine wave correction

Product never used, packaging damaged during transport. Unopened product, repackaged in our warehouses, in perfect working condition, warranty available.

Features: 1. Dual LCD digital display for real-time viewing of output voltage and battery voltage. 2. Fault warning function. In addition to various audible messages, these can be displayed more intuitively on the screen (such as battery undervoltage, battery overvoltage, overload, high operating temperature, output short circuit, etc.). 3. The product adds a timed shutdown function in case of overload, which solves the tricky problem of inverter protection when sensitive electrical devices are switched on. 4. Intended for the low-power, non-professional user market, it adds a positive and negative feedback protection function. 5. Oil-sealed fan with intelligent temperature control function. When the inverter is running, it can operate at a certain temperature, which is both energy-efficient and quiet. 6) Digital microcontroller control, more precise output waveform and frequency, more precise output voltage, and fast response speed of the protection circuit. Output voltage: 110V/220V (optional) Output voltage range: 110V 10% / 220V 10% Frequency: 50Hz / 60Hz at 9.5V High voltage protection: with a maximum protection voltage of 15.5V Overload protection: Output short circuit protection: Forward and reverse protection: Output voltage stabilization: Yes Buzzer protection: USB connector: 2.1A x 2 Input connector: terminal Output connector: international universal plug Product dimensions (mm): 161mm / 6.28in. x 112mm / 4.37in. x 56 mm / 2.18 in. Package includes: 1 x inverter (other items in the picture are accessories and are not included). Please note: 1. The size is measured manually, there may be a 1-3 cm error, I hope you understand! 2. Due to different monitor calibrations, the color of the item shown in the picture may be slightly different on your computer screen.
