Concerns the 12-220volt 500wat honest.... it works everything up to 350-400 wat.. I have it for 4 years... 60-inch TV... 150 wat fans 2x20wat.... and 4 LED bulbs 5wat.... and a kettle 350 wat but I only run it alone for a coffee...... I have news .... it works inverter refrigerator freezer.. 200 wat modern.... but be careful it is the modern inverter without drawing 5-10 times more power at startup..... incredible.... the freezer that does not have an inverter it cannot handle.... The washing machine starts normally in cold but when the spinning starts which requires many revolutions it cuts off.... I will get the bigger one and will return

I don't know if it was the specific batch's fault, but as soon as I tried it, it started whistling as if the battery I had connected it to had run out. It turned out to be defective. The company replaced it immediately. The second one didn't whistle, but its performance was zero, resulting in the screen it was connected to making a sound as if it was flickering. Which means it could potentially burn it. I gave it two stars (instead of one) because the supplier took it back and issued a refund.
