Customer Reviews for VEVOR 3000W Voltage Converter Transformer Step Up/Down 220V-110V /110V-220V CE

Works as expected. I have been using it for nearly continuous operation of device at 110...120V from 230V mains (50Hz) on resistive power of 250W. The indicated voltage on the output varies from about 112V (load on) to 117V (load off) according to the built-in voltage display. The device runs cool, no considerable temperature rise or noise. This indicates good efficiency.

Îl am de câteva luni și este extraordinar. Îl țin non stop în priza și Îl folosesc la un aparat de cafea consum de 1.8kw nu am.intampinat nici o problmea

It’s been working great so far. We have bought both the 2000W and 3000W transformers, so we can use our American devices here in Europe.The price was good and shipping really fast, within a few days. My only complaint is that I wished it was a bit smaller in size. If you need a step down voltage converter this is the one to buy.

Everything worked as expected. One time cost for long time convenience :) Funny that 100 characters minimum is required :)

I bought this 5000W version but use it currently only for my Japanese 110v computers to run in Europe 220v. So it does not get even warm. Later when I move to Japan I'll be able to use kitchen machines etc... That is why I bought the 5000W version. I had to change to cable from US plug to EU plug, but that was easy done if you are handy with soldering. You can also use a plug adapter. You cannot find a cheaper 5000W unit. So price quality wise this is a very good deal. Features would have been 5 stars if a EU plug version would be sold. Quality I cannot judge fully yet, so 4 stars for now.

very good quality. very happy with this transformer and lightweight in comparison to the bulky yellow transformer

It works for the purpose I've bought it, is a bit noisy but is normal. Is adequate for use with kitchen equipments. The delivery delay is the only complain (about 1 month to arrive), but the shipping was free so is understandable.

I'm using the transformer to step down voltage to 120V in two HiFi systems, a slight hum is audible through amp/speakers. Remember USA is 60Hz, Ireland is 50, so Hz can be an issue with US products. It was tripping the 20amp breaker too often, so I installed a new one, still trips from time to time?.......thats without a load on the transformer. I wish it had four 120V outlets......only has 2. My loads are light, not pulling many amps. U.S. multi socket extension outlets do not work when stepping down with a transformer as the neutral leg of the transformer has 240V (I found out the hard way, I should have tested with my multimeter first) Otherwise, the transformer is fine, price is good. I had difficulty with the French websites address format, my address was all haywire, I took a chance with my eircode.

Step down voltage 250to120+1700wneeded3000w to run without tripping on startup.works perfectly.
