Congsin's Portable 150W Modified Sine Wave Inverter powers your journey! This versatile Car Power Inverter with USB acts as a reliable 12V to 220V converter, ensuring an essential off-grid power supply. With dual USB ports and a universal socket, enjoy convenient power on the go.
Congsin 500W 12V to 220V inverter delivers reliable off-grid power with its modified sine wave design. This portable 500W DC to AC power inverter efficiently converts 12V DC to 220V AC, ideal for outdoor and emergency use. Trust Congsin for stable, portable energy solutions.
This 200W Modified Sine Wave Car Power Inverter is a compact and practical power conversion device designed for vehicle use. It supports dual input (DC12V/24V) and outputs AC220V, compatible with various electronic devices. Equipped with a Type-C port and dual 3.1A USB outputs, it can charge laptops, phones, cameras, drones, and other small electronics simultaneously—perfect for outdoor travel, emergency backup, and mobile work scenarios.
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.
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.
