Customer Reviews for VEVOR 500VA Auto Variable Voltage Transformer, 3.84 Amp, 110V Input 0-130V Output AC Voltage Regulator Power Supply, with 4 Extra Fuses Thermal Control Switch for Home Industrial Office

Works perfectly! Looks well built and has a heavy transformer. Sweeps through the voltages without any issues.

I use this device for slow startups of vintage audio equipment to prevent capacitor blow ups after gear has sat for extended periods of time. It needs to be checked with a volt ohm meter when you first get it because the knob and digital read out should be calibrated so you can double check the readings and notate it! I don't know what power China uses but I get the idea it's not 120V. ..:)

It won't work for what said it would and they won't make it right. Junk . this is a bad company.won,t make a return

This is without a doubt a really nice unit. It does exactly what it says....the digital readout is super nice to have. I would not buy one of these units without the digital readout. I am extremely happy with the overall quality. Great unit, fair price. Great experience. Would buy again for sure. Bill P.

Very nice and clean voltage works well for any brushless fan motor and also it’s good quality for the price point. So if you’re looking for something with good quality and good price. I would recommend this.

Use this with coffee bean roaster to boast the voltage Works great

Good quality, well built, regulates exactly what I want.

I bought this VT for my electronics hobby. It’s a quality unit. Anyone in this field knows how important these are to have. If your in need of one this one is really great to have.

I've used this unit to run a heating mantle for a soxlet extractor set up and it works great.

does the trick well with zero issues. very smooth to operate and very quiet, though it is pretty heavy.
