Q&A
Can it drive a 3P air conditioner and an electric oven at the same time?
Total power needs to be calculated: the rated power of a 3P air conditioner is about 2200W-2500W, and the electric oven is about 1500W-2000W. The total power is 3700W-4500W, which exceeds the 3000W continuous power, so simultaneous use is not recommended; if used alone, the 6000W peak can meet the startup needs of both, and the battery capacity must be ≥200Ah (12V) when used alone.
How to connect the battery with the battery clip?
Connect the positive and negative poles of the battery clip to the positive and negative poles of the battery respectively, and ensure a firm connection.
Can I customize the color and logo?
Yes, OEM/ODM customization is supported.
Can it run inductive loads like fridges or tools?
Yes, pure sine wave output supports all load types.
1000W Modified Sine Wave Inverter, DC 12V to AC 220V Power Inverter with LED Display, 3 USB Ports, 1 Type-C, 1 DC 12V Output & Two Universal Sockets
Our CS1000DDBC 1000W modified sine wave inverter is a professional power conversion device that converts DC 12V from batteries into AC 220V electricity. It is designed with user convenience in mind, featuring an LED display for real-time status monitoring, multiple charging ports (3 USB, 1 Type-C, 1 DC 12V) and two universal sockets to power a wide range of devices simultaneously. Its compact size (250×95×55mm) and lightweight design (NW: 0.84kg) make it easy to carry, ideal for outdoor activities, emergency home use, and on-the-go power needs.
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.
