VEVOR Voltage Converter Transformer, 2000W, 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

Excellent product! One of its best features is the automatic input voltage detection, which makes it very convenient to use and helps prevent issues when connecting electrical appliances.So far, it has been working perfectly without any problems. The build quality is impressive, and it feels very solid, sturdy, and designed to last.I’m extremely satisfied with my purchase and would definitely recommend it!

So far so good. Use it to power our house 220v water pump when feeding the house with solar (that only powers the 110v sockets). Quiet operation. A little heavy, but that is to be expected if you want a robust feeling appliance.

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.

It is a great one! I got this a long time ago and still works without any problem!

Pros: Excellent value, reliable performance, consistent brand quality.Cons: Basic design, not the flashiest unit on the market.Full Review:It honestly seems like Vevor is taking over the market lately. This voltage converter is just another product I’ve bought from them that is holding up perfectly under regular use.I’m not saying it is the absolute fanciest or most luxurious device out there, but the build quality is solid and the overall value is tough to beat. This is one of multiple products I now own from this company, and so far, so good across the board. If you need a reliable transformer without paying a premium, this is a safe bet.

I bought this voltage converter specifically to use my 220V Dyson hair dryer in the U.S. I’ve been using it for about six months now, and it has been working reliably with no issues. Very satisfied with the purchase.

Works well enough, it came with a standard 3 prong plug that I was able to use with a heavy duty plug wired into the 220 inverter I have and it puts out 112 volts on the low side and 217 on the high side, I'll have to get some euro style plugs to use the 220 off of it but probably won't need that as we have 220 on the house. Haven't noticed any odd smells or heat but I'll update as I use it, not very noisy once it gets running so that's a plus

It's exactly what I wanted, but im not gone lie its bigger then what I thought

This transformer is dangerous and a fire hazard. I was having lots of issues with it tripping up my fuses until I found out that it does not abide to electrical standards. When you connect the multimeter to the Neutral connection and Ground, the reading should be 0 (Zero). However, it came up as 220V! Really, really bad. I even got shocked a couple of times because the neutral wire was live!!!! This transformer should be excluded from Amazon and from all online shopping. It will kill someone someday or catch a boat/house on fire.

Très bon article, pratique et efficace

I brought my 1963 American Singer sewing machine and modern Cuckoo 3-cup rice cooker to Europe when I moved without realizing I'd need not just a plug adapter, but a full-on step-up/down voltage converter transformer to reduce European voltage of ≈220v to ≈110v. What happens when you try to use appliances with the wrong voltage? My rice cooker's settings couldn't be accessed correctly---stove-top rice for weeks :-( ---and creepily enough, once I stepped on my sewing machine's pedal, it tried to keep sewing by itself even when I held the flywheel; even when plugged in but not in use, the higher voltage heated up the motor and burned the casing. I'm lucky it didn't burn out the motor completely. Lesson learned!While this transformer is expensive, large, and heavy, it does exactly what I need it to do, which is handle surges of power use like when the rice cooker starts a cooking cycle, does it quietly thanks to its toroidal core, and allows me to step up or down with the flip of a switch (in the back) should I need to power a European device back in the US. There were cheaper models, and smaller ones, but this machine had all the specs I needed, and frankly, the handle on the top of the transformer helps me transport it when I need to. All in all, well worth the investment to keep multiple sentimental appliances from the US working.PRO:- Steps up and steps down- Toroidal core is nearly silent- Gives you a readout in front to show when power use changes- Power switch (blue) is in front for easy access- Handle on top for transportingCON:- Heavy- As large as a small kitchen appliance, so it'll take up counter space- €50±, which is as expensive as buying a new appliance that doesn't need a transformer

Provato è perfettamente funzionante. Alimenta il mio impianto audio in maniera impeccabile ( alcune casse sono da 120v di importazione americana) e questo convertitore fa egregiamente il suo lavoro!!! Consigliato L acquisto

Gutes Preis LeistungverhältnisFunktioniert primaHabe einen Spannungs-Begrenzer benutzt, damit die haussicherung nicht rausfliegt beim Einschalten
