4000W Car Power Inverter — Modified Sine Wave, LCD Voltage Display, 300W Continuous (4000W Peak), Dual USB (Max 4.2A) & AC Socket, Voltage Protection

Overview: Compact automobile power inverter delivering 300W continuous output with 4000W peak surge capacity (confirm total connected load does not exceed 300W). It features one AC outlet plus two USB ports and can be powered from a vehicle cigarette lighter cable for convenient onboard use. For draws above 150W, connect via the included crocodile clips. Status indicators and protection: Two front LEDs show operating condition — green indicates normal operation; red signals a protection state (low voltage, high voltage, overheating or overload). If the red LED illuminates, switch the unit off, identify which protection has triggered and resolve the issue before restarting. Intelligent LCD display: A color LCD provides real-time readouts of battery input voltage, output voltage, battery capacity, selectable frequency (50Hz or 60Hz) and current load percentage so you can monitor inverter performance at a glance. Charging and output capabilities: The single AC socket and the dual USB interfaces can be used simultaneously. The two USB ports deliver a combined maximum of 4.2A for fast charging, capable of fully charging mobile phones, computers, laptops, breast pumps, atomizers, razors, medical devices, emergency gear and similar automotive appliances. Built-in safety features and cooling: Equipped with a fuse, safe charging design and cooling fan to reduce heat and power loss. Protection functions include overvoltage, overload, overcurrent, short circuit, undervoltage and overheating protection. Portability and fit: Lightweight and compact, this inverter is designed for travel, camping and work trips. It can be connected to nearly any vehicle with a 12V power output, providing on-the-go charging and AC power wherever you need it.
