FAQ
How long does it take to become an authorized distributor?
The process typically takes 2-4 weeks, depending on the discussion and agreement finalization.
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.
What capacity battery is needed to meet long-term use?
It needs to be calculated according to the total power of the device, the formula is "Battery Capacity (Ah) = Total Device Power (W) × Usage Time (h) ÷ Input Voltage (12V)". For example, to drive a 1000W device for 5 hours, the required battery capacity = 1000×5÷12≈417Ah, it is recommended to use 2 200Ah batteries in parallel (total capacity 400Ah, actual usage about 4.8 hours).
Does it only support DC12V input voltage?
The regular model has DC12V input, and other input voltages such as DC24V can be customized. Please consult customer service for details.
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, 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
