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 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.

We bought a Kimchi freezer/refrigerator that uses 240v and had to buy a 240 to 120 inverter. So we chose to get this product. After few months of use, I conclude that it's working as described by seller. Giving constant and steady voltage. Whenever I need to plug 110v extension to use, I just simply plug into the unit and it works flawlessly too.

Product is good and working great but no multi plug for 220V output. So if you have UK 3pin or Australia pin you need to get adapter

Good price, works great

It came with a wire loose inside the unit. The LED wire was just floating around near the AC lines which is dangerous if they touch. The unit is rated for 5000VA but doesn't have wired sized appropriately to hit that rating. The transformer has a pair of 14AWG windings but only connected to a single 14AWG wire to connect to the power outlets and inlets. This limits the current to 15amps or 1800w at 120v. 240v output is not relevant since it is limited at 15amp inputs current which would still be 1800w.I read that it was an auto transformer so I gave it a shot since I wanted to use it for converting 30amp 120v at camp sites to 15A 240v to run a 3500w induction top while camping. I would have to open up the transformer to upgrade the single 14AWG wire to 10AWG to handle the current properly. I am debating if I should rework the transformer or just return the unit.

This Heavy Duty Voltage Converter comes in really handy for operating European devices in the USA. Its Bold & Colorful voltage display shows up under bright conditions.Possibly the best referral is from an electronics dealer who said it was really robust. When I quoted the price, his jaw dropped!

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!
