Review on Yinleader 800W Step Up & Step Down Voltage Transformer Power Converter - Convert 220V to 110V or 110V to 220V in Global Regions by Isaac Simpson

The device has a toroidal transformer (doughnut shape) used in high power amplifiers (200W-5000W). such pure power. Only the fuse and switch (3 wires to 2 wires) go both ways. Runs quiet #1, works well with a 65 watt humidifier #2 and doesn't seem to get hot after a few hours. simply user-friendly period! Note: Goldsource 500W Goldsource Boost and Buck Converter High Power AC 110-120V to 220-240V Converter with US Standard and Universal Sockets and USB DC 5V 500W Not Working and Fuse Blown. and sang out loud. so I'm talking about buying that. Just buy one with 200 watts here.
