VEVOR Voltage Converter Transformer, 5000W, Heavy Duty Step Up/Down Transformer, Convert from 110 Volt to 220 Volt and from 220 Volt to 110 Volt, with US Outlet EU Outlet 5V USB Port, CE Certified

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.

This was a lifesaver for my music 🎶.

running some plant lights with it and its worked great so far. wish it maybe had an additional plug or two but all good.

Heavy, solid and works fine.

I recently had a disappointing experience with a 110-240V/240-110V voltage converter. After just a few days of use, the device stopped working entirely. While it initially performed well—running smoothly and quietly—it suddenly lost power and wouldn’t turn back on. Additionally, the converter is quite bulky and heavy, which made it less convenient to use. Overall, I expected better durability and reliability from this product.

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.

Very good quality, easy to setupI can use all kitchen appliances I bought back from Germany

Lo ame súper bueno y de buena calidad tal como lo esperaba
