3000W Full-Power Pure Sine Wave Inverter (Labeled 6000W), DC 12V to AC 220V Power Converter, Suitable for High-Power Devices
This pure sine wave inverter (Model: CS3000PSW-L6000) features "3000W full continuous power output + labeled 6000W peak power." Adopting pure sine wave output technology (waveform distortion rate <2%), its power quality is close to mains power, which can safely drive high-power precision devices such as air conditioners, refrigerators, electric tools, and medical instruments, avoiding equipment malfunctions caused by unstable waveforms. The device supports DC 12V input (compatible with 10.5V-14.8V wide voltage): 3000W continuous power meets long-term stable power supply, and 6000W peak power easily copes with the instantaneous startup impact of devices. Equipped with 4 AC universal sockets (16A) and 2 USB 3.0 fast-charging ports (22.5W/port), it can supply power to 6 devices simultaneously. Built-in six-fold protection (overload, overvoltage, undervoltage, short circuit, overtemperature, and reverse connection), combined with dual intelligent silent cooling fans (noise ≤45dB), balances high-power performance and safety, making it suitable for home emergencies, outdoor engineering, vehicle-mounted power supplies, small commercial and other scenarios.
