T Series 2000+ Watt Voltage Converter Transformer - Step Up/Down - 110v to 220v / 220v to 110v Power Converter - Circuit Breaker Protection, CE Certified [3-Years Warranty]

This transformer worked with my 120 VAC inverter generator to start and run my 1 HP 230 VAC well pump. I am pleased with how it all worked. The transformer ran cool with about a 55% of running watts load.

It worked as described. Using it to power an arcade game that runs 220V and I'm using 110V.Works as described. It's' quiet as well.

This convertor arrived today. I have moved from overseas back to the US (115V) and I have a tube headphone amplifier that was purchased in a country with 220V. I considered having the transformer changed but that was expensive and time consuming. I thought I would try this approach and I am very glad I did. This convertor works perfectly and is totally silent in operation. I could not have asked for a better more affordable solution to the problem. Highly recommended.

My wife received a vacuum cleaner as a gift from her uncle. Unfortunately, it was made for the Korean market and had the wrong type of plug for use in the USA, not to mention the voltage of the machine. It sat in the box for 21 years until I saw this ELC T Series 3000+ Watt Voltage Converter Transformer - Step Up/Down and realized it was exactly what I needed.Easy set up - plug it in, turn it on. The vacuum cleaner worked like a charm, no circuit breakers were blown, nothing overheated, no fires or sparks. I call that a success. Be sure to check your requirements carefully, as there are similar looking machines that don't do the same thing.

I read the reviews about some of the electrical connections being not so good & caused melted wires and such. I'm happy to report all connections are soldered and or very strong crimps. Nothing was loose. They must have been improving their techniques based on the reviews here. Nothing got hot during my 20 minute long test pushing 3,000 Watts at 240v into it and 120v out of their 5000 watt model. The transformer reached 102° f and one of the connections on the push button breakers reached 110° f. I can almost handle my hot tub that hot so this is no problem at all for electronics. In the stock case it only gives you access to one leg of the 120 volt output. That's a shame because it means you can't balance the loads so you're literally transforming all of the Power you're pushing through it instead of only the imbalance between the legs on its output. It doesn't matter to me because I was harvesting the transformer for an off-grid project. After the test I removed the large toroidal center tap transformer and used it with a MPP hybrid inverter from China that only puts out 240 on line 1 and neutral on the other. It's working perfectly to transform that to American 120-120/240. I can feel the transformer humming and I measured its idle consumption at 5 Watts. I ordered eight of these transformers and apparently four of them got damaged in shipping and sent back. No duh! Because the four that showed up weren't packed correctly at all. The box the transformer was in was sliding around in a giant box with some popped giant bubble wrap. The transformer of one of them must have taken quite an impact because you could tell it was tweaked sideways in the case therefore loosened the bolt that holds it down to the bottom of the metal case. Not a big deal though, I just shook it & when I heard the transformer loose I opened it up and tighten the bolt easy peasy.

I bought two of these and have the same problem on both. Unfortunately I didn't bother to check them until my return window had closed...On the 220 outlet, with 115v selected as the input voltage, you should get 220v/240v on a meter touching the L to N sockets. It does.From L to Ground you should get 110v/120v. It gets 220/240v.From N to Ground you should get 110v/120v. It gets 0v.I read another review by SDBob on May 16th, titled, "Use Caution" where I believe he is describing the same problem. He says the solution is to switch the white and black wires internally. Have looked internally and am not comfortable doing that without having it looked at by someone with more electrical knowledge than me but seems like that may not be the right solution on my two from what I can see.Very disappointing and I will not be buying or recommending any more of this brand.If the vendor wants to reach out and give me advice on rewiring this with some photo exchanges I would upgrade my review to 3 stars but otherwise 1 star is generous because it just plane does not work and I worry it could damage equipment that gets plugged into it.

So easy to use. I bought an Nespresso machine in England and didn't even think about the electric conversion, so got home and went to plug it in and was like uh oh. But bought this step up step down and now I make expresso with my beautiful periwinkle colored machine from London. So happy!

après la déception avec l'autre appareil, celui-ci est quasiment, read-how-to, plug and use, lire les consignes, branchez et utilisez et voilà, ça marche et très bien. Pas très bruyant et efficace.

Je ne l'ai pas encore utilisé, car je le ferai seulement quand je vais me rendre à l'étranger; mais j'ai confiance au produit et pense toutes fois le recommender car j'ai confiance que ca va fonctionner

El Convertidor trabaja muy bien y no se calienta. Me a sido muy útil para convertir de 120V a 240V

transformer plugged into north American delivering 220 no problem. Able to run European alliances on north American circuit. Haven't tried European powering north American yet. Been running for about two weeks not even getting very warm.

Llego muy bien protejido, funciona execelentemente bien, lo uso para mis maquinas de carpinteria (Hobbie) de mediana potencia y se comporta muy bien.
