Q&A
How long does it take to become an authorized distributor?
The process typically takes 2-4 weeks, depending on the discussion and agreement finalization.
Which plug types are supported by the universal socket?
The universal socket is compatible with most national plug specifications, such as GB, US, EU, etc., and can meet the use of devices in different regions (some require adapters).
Does it include protection features?
Yes, it has sixfold safety protection for reliable performance.
How does the UPS function of this inverter work?
When the external power supply is normal, the inverter powers the device while charging the battery; when the external power supply is interrupted, it automatically switches to battery power to ensure uninterrupted operation of the device.

3000W Full-Power Pure Sine Wave Inverter, DC 12V to AC 220V Power Converter, Suitable for High-Power Precision Devices
This 3000W full-power pure sine wave inverter (Model: CS3000PSW) adopts pure sine wave output technology (waveform distortion rate <2%), and the output power is highly consistent with mains power quality. It can safely drive high-power precision loads such as air conditioners, refrigerators, medical instruments, and small industrial equipment, avoiding equipment malfunctions or shortened service life caused by unstable waveforms. The device supports DC 12V input (compatible with 10.5V-14.8V wide voltage), continuously outputs 3000W full power, and has a peak power of 6000W, easily coping with the instantaneous startup impact of high-power devices; it is equipped with 4 AC universal sockets (max current 16A) + 2 USB 3.0 fast-charging ports (22.5W per port) to meet the simultaneous power supply needs of multiple devices. Built-in six-fold safety protection (overload, overvoltage, undervoltage, short circuit, overtemperature, reverse connection), combined with dual intelligent silent cooling fans (noise ≤45dB), it achieves the triple advantages of "high power + high safety + low noise," suitable for home emergency, outdoor engineering, vehicle-mounted power supply, small industrial scenarios and other fields.
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.
