VEVOR Voltage Converter Transformer 5000W Heavy Duty Step Up Down Transformer Convert from 110 Volt to 220 Volt

Ok so I've had this for a few weeks and it works well. A simple unit with a good quality Toroidal Transformer and not much else. The internal connections are good, and straight forward and there is virtually no electronics inside other than the transformer. It does have a light and a USB outlet but these are not needed to make it work. So reliability and durability is good, the front meters are not totally accurate and may be off by a bit. But the power coming out is within specs. It will not clean up the power since there are no other electronics or filter circuit inside. It would be nice to have a meter showing the incoming power in addition to the the outgoing power. I dont load this thing up so I dont really have a buzz or hum that could be if you run a lot of power through it. Even then there are things that can be done to mitigate the noise. It also only has a light to tell you the incoming power is plugged in. All in all it fits my needs perfectly and is a good solid converter that is very simple and very quiet with a very little extra draw on the power to achieve the power conversion from the converter itself. So power loss because of the unit itself is almost non existent. I wish it would switch incoming power automatically rather than having to flip a switch but it keeps the cost down and reliability up. This unit is not something you would want to tote around, its heavy. But if you need reliable power conversion I can recommend this unit. Read more

I use this unit as a cheap way to convert 120 to 240. I rewired the unit for my RV to install a minisplit that is make 3000W. Note the wire inside was very much undersized for 45amps. I replace most of the wire and insured the power went directly into the transformer instead of looping through each outlet first with is totally crazy. Really all I was looking for was the transformer inside the rest of the unit is OK and I liked the metal housing. I removed the rear breaker (cause I already have my own 30 amp breaker) and the switch to go between 120 and 240 input. I also cut holes into the metal and installed conduit. I found after my rewire the displayed voltages are off from what is really going in but they are close. I left the front breaker as a disconnect. The packaging works well to strap it down in my RV. Works really well if looking to put a 240V mini split into an RV that really only does 110V. Read more

I used this voltage converter in Europe and it performed exactly as intended. I ran a large microwave, vacuum cleaner, and juicer with no issues whatsoever. Excellent build quality and reliable voltage conversion that fully met my needs Read more

Works great. If you are taking it abroad (to 220-volt country) don't forget to change the default switch in the back of the unit from 110 to 220 Volt before you first plug it in or modify the plug. If you don't? Then be warned to expect a big spark, loud noise, smoke and a toast unit. Read more

I bought the 5000W elevator for one device I don't use frequently, but when I do, it's for long continuous periods—typically 12/15 hours. The device requires 230V and at least 13A. I’ve used the elevator twice. Initially, it shows 253V output and 126V input, but it stabilizes at +/- 232V and 123V during the use. It runs continuously, gets warm but not too hot to the touch, and has a slight odor. It's heavy, but so far, it works well. Based on my calculations, a 1500W elevator should have been sufficient, so I initially tried a Dynastar, but it didn’t work. Read more

Works perfectly Read more

Well built, transformer, I unpacked it and gave it a try, it was smooth, stable and quiet. Read more

This is a great converter transformers, just change It’s input plug to be better coupled to your 220V. Read more
