Customer Reviews for VEVOR 500VA Variable Transformer 110V 60Hz Input Voltage Digital Display 0-130V Output Automatic Voltage Regulator for US Plug…

Larger, heavier than I'd anticipated, but did the job well. Have the feeling that if simply maintained, it will last and continue to work well for a long time.

Works great for working on guitar amplifiers

Performance is normal and provides safety on power up for electric projects. This thing will outlive me for sure.

Cheap crap it held up for 2 weeks before it fried itself for no reason! Don't waist your money or time!

This voltage regulator is built like a tank. Made to last a lifetime. Very precise regulation, awesome product.

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.

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

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.

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

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.
