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.

Works perfectly. Bought this to run a 110v portable AC unit in our sail boat while working on it in the boat yard. It never missed a beat running 24/7 for a solid week and the incoming 240v was 50 hz not 60 like in US. Unit is heave and seems like a quality build. definitely would recommend

Works Great! No issues so far!

Very good and powerful converter. It is very reliable and well designed. I will buy again.

Item works very well and reached in time.

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.

Working well

This VEVOR transformer is exactly what I needed for my international appliances. The 2000W capacity easily handles my European kitchen equipment, while the multiple outlet options (both US and EU) plus the USB port let me power several devices simultaneously. Setup was incredibly straightforward - just plug in and select your voltage. After weeks of heavy use, it runs quietly with minimal heat buildup, and the LED display provides clear status information. Perfect for anyone living between voltage standards or using imported electronics!
