Power inverter sockets


  • Intelligent integrated circuit control
    Unique front and rear dual soft start technology, CPU core, SPWM pulse width control technology, special constant power technology, anti-reverse diode technology.
  • Pure sine wave
    100% pure sine wave output, low distortion, waveform and main power line AC waveform are basically the same, equipment accuracy is small, low interference, low noise, strong load capacity, can meet any type of AC load, without damaging the load.
  • Imported parts
    The materials are imported components, and the panel uses double-sided circuit boards to ensure high quality and high performance of the products, and to match the excellent quality of the detailed molds.
  • Aluminum alloy casing
    The surface of the aluminum alloy shell is sprayed and anodized, which is small in size, elegant in appearance and easy to carry.
  • Working instructions intuitive working state
    When the inverter undervoltage/overvoltage, overload, overtemperature, short circuit, the LED indicator lights.
  • Multiple protection functions
  • Fault warning/buzzer alarm reminder
    When the inverter high voltage, low voltage, over temperature, overload protection function is turned on, once the protection of the inverter is triggered, the inverter disconnects the power supply and the load enters the protection mode for the first time, and issues an alarm through the buzzer alarm device. Make your use more secure.

Pure sine power inverter applications

Tips: How Much Power Pure Sine Wave Inverter Can Drive 300W Household Appliances?
Must be more than 300W pure sine wave inverter to drive 300W household appliances, preferably larger, such as 500W. Usually, the input voltage of the inverter is 12V, 24V, 36V, 48V, and other input voltages are also available. Other models can output different voltages. The key parameters of the inverter are: output power, conversion efficiency, and output waveform quality.

Work as expected.
I bought a 24V 300 watt pure sine wave inverter from, this is a nice choice. I am using this inverter in a home application. I wanted to put together a small solar system to run my refrigerator and freezer during a power outage. Nice product, solidly built, easy to install and works very well.

A good small inverter
I have used many inverters before. I think this 24v 300 watt pure sine wave inverter is the best, and its performance fully meets the advertising requirements. I will install it permanently in the vehicle to power laptops, test equipment and mobile printers.

Quiet inverter
I have never used such a useful inverter. I have bought a lot of inverters before. It is best to buy it at It has been used for about 3 months now. It can power a 1000 watt induction cooker. It runs quietly, with no hum or electrical noise.
