4000W 12V Modified Sine Wave Car Power Inverter — 300W Continuous (Peak 4000W) with LCD Display, Dual USB (Max 4.2A) & AC Outlet

Compact 12V car power inverter that converts vehicle power into usable AC and USB charging. Delivers 300W continuous output with a 4000W peak surge — please ensure the rated total power of the connected equipment is 300W. Unit includes one AC socket plus two USB ports for charging and can be powered via the cigarette lighter cable for convenience; if the output power is greater than 150W, use the crocodile clips to charge. Status indicators and screen: a green LED shows normal operation, while a red LED signals protection mode (low voltage, high voltage, over temperature or overload). Turn the inverter off, diagnose which protection triggered, and resolve the issue before restarting. The color intelligent LCD displays battery input voltage, output voltage, battery capacity, frequency (50Hz or 60Hz) and current load percentage in real time so you always know the inverter’s status. Fast charging and outlets: the inverter provides dual USB interfaces alongside the AC outlet (one AC socket supports simultaneous operation of two USB charger interfaces, Max 4.2A). It supports 100% fast charging for phones, computers, laptops, breast pumps, atomizers, razors, medical and emergency devices, meeting the power needs of many automotive appliances and serving as an emergency power source. Protections and cooling: built-in fuse, safe charging design and an active cooling fan protect the on-board power converter from overheating and improve efficiency. Comprehensive protection features include overvoltage, overload, overcurrent, short circuit, undervoltage and overheating protection. Portable design: lightweight and compact for travel, camping or work. Compatible with nearly any 12V power output vehicle, it provides on-the-go charging and power wherever you drive.
