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.

Tips: How Many Batteries for 500 Watt Pure Sine Wave Inverter?

The input voltage of 12V pure sine wave inverter is 12V. It is necessary to use two 12V 7A batteries in parallel. It is recommended that 50A battery, 500W can drive TV, set-top box, audio. If a 1000 watt pure sine wave inverter is used, do not use a 1200 watt rice cooker.

This is exactly what I expected from a pure sine wave inverter
This is the first sine wave inverter I've ever purchased, and I didn't know much about it, but I needed one for my solar setup. After some research, I came across this 500W pure sine wave inverter. So far, it has worked flawlessly for my setup.

Wonderful reasonable priced inverter.
No cons so far! Runs my compact fridge, cordless tool charger, as well as my corded power tools!
I direct wired mine, because I know a cigarette lighter plug is only good for around 150 watts, and this pure sine wave inverter is rated at 500 watts. As with all Bestek products is is very high quality, compact, and a great value!

Happy with 12V pure sine wave inverter.
Works as required. Good price for full sine. Running furnace as backup during power outage. This is a fantastic pure sine wave inverter. I will buy more if I need it and I will recommend it to my friends.

Inverter worth buying
My generator burned out after a storm and I need an inverter to replace it, the inverter works great, I can use it to charge any electronic device in my house, if I connect this inverter to a low battery it will scream a red light, otherwise it will give you a green light to tell you it's ready, which is awesome!
