Q&A
Can this 2000W inverter power an air conditioner?
If the air conditioner power is within 2000W and the input is AC220V, it can supply power normally. It is recommended to ensure stable power when starting.
Can other input voltages be customized?
Yes, the regular is DC12V, and DC24V, etc. can be customized. Please consult customer service for details.
What’s the main difference between your OEM and ODM services?
OEM uses your brand on our standard products; ODM creates entirely new products based on your concept or specification.
Which regional plugs can be used with the universal socket?
The universal socket supports most national plug specifications, such as GB, US, EU, etc. (some require adapters), and can meet the use of devices in multiple regions.
2000W Full-Power Pure Sine Wave Inverter, DC 12V to AC 220V Power Converter, Equipped with 3 AC Universal Sockets
This 2000W full-power pure sine wave inverter (Model: CS2000PSW-3S) adopts pure sine wave output technology (waveform distortion rate <3%), and the output power is close to mains power quality, which can safely drive precision electronic devices such as computers, inverter air conditioners, medical instruments, and audio equipment, avoiding equipment malfunctions or damage caused by unstable waveforms. The device supports DC 12V input (compatible with 10.5V-14.8V wide voltage), continuously outputs 2000W full power, and has a peak power of 4000W, easily meeting the instantaneous startup needs of high-power devices; it is core-equipped with 3 AC universal sockets (max current 16A), which can supply power to multiple home appliances or devices at the same time, and is matched with 2 USB 3.0 fast-charging ports (22.5W per port), balancing high-power supply and digital product charging. Built-in five-fold safety protection (overload, overvoltage, undervoltage, short circuit, and overtemperature), combined with dual silent cooling fans (noise ≤42dB), it achieves both safety and stability, suitable for home emergencies, outdoor operations, vehicle-mounted power supplies, small commercial and other scenarios.
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.
