Since I was 15 years old, I have longed to own one of these way back when RadioShack was still a real electronics hobbyist's store. This device is rock solid. With respect to accuracy, this is a transformer after all, so the voltage that comes out depends on what goes in. Since most U. S. house AC is actually 120VAC or even slightly higher, divide your actual house AC voltage by the rated 110VAC on the unit, and multiply the voltage on the dial by that factor to estimate the voltage that actually appears at the socket; turning the dial to 110 will give a little over 120VAC, and turning it to 120 will give you about 132VAC out. Definitely something to keep in mind. The front panel meter is a good guide for the voltage that actually appears at the socket.

Actually it works very well. The indicated voltage on the display VS the measured voltage with a multimeter is off by 2-5 volts on the high range but os ok for my needs.

this unit fits my needs perfectly, i wanted a speed control for my angle grinders and cut off saw it works exceptionally well for my brush type motor driven tools, and looks to be quite well made. i ordered and received the unit with the led voltmeter, and it is fairly accurate up to about 70volts or so and is off maybe 8 volts at full scale, which is not bad at all and certainly good enough for most needs. so far i have not be at all disappointed with vevor products, and happy to say this unit is not the exception.

Works as listed

Best speed controller for the money I've tried others and was disappointed. Great product

Leonardo

Good product

Excellent product, great price and easy to use. Would certainly purchase it again. Works very well controlling the Christmas lights

mobile_bob

quite well made unit, and more than what i expected

Set My Vintage Amp Voltage to 117vac

Fast delivery - easy setup - Bench tested the input & reduced output voltage / very consistent. Reduced the input AC voltage to my 1962 Fender Bassman 100 to mfg. spec. 117 vac. I didn't notice any real difference in the sound but expect this will extend the life of the tubes greatly. My studio AC output is 122 vac at the outlet. You will have a hard time beating this price point and quality. Does the job easily. Thanks VEVOR!

mike

Very pleased!

I mistakenly thought this unit was faulty but turned out to be my motor.Please disregard my previous review.

Richard Beal

Retired radio operator

I love my variable transformer, I use it on my vacuumed tube shortwave receiver, thanks I use it to reduce the voltage to 110 and start it out slowly to let the tubes warm up

Excellent unit

Faultless performance. It is worth it to buy the 20 amp unit vs the 15 amp believe me. Overvoltage is also a plus.

Barkyhill

Good, basic bench tool.

Generally well made from the outside. Not quite as much so inside. This is typical for all of these on Amazon or eBay. Meter is nearly on-target at about 117VAC, but is off abt10V below 50V and abt 5V at130V. With an external VOM, you can dial it in. Use the meter and the guide marks by the knob as range not actual values.It will be fine for my workbench with smaller "boat anchor" ham radios after I build a light bulb current limiter and add an isolation transformer (harder to find).
