T Series 1000+ Watt Voltage Converter Transformer - Step Up/Down - 110v to 220v / 220v to 110v Power Converter - Circuit Breaker Protection, CE Certified [3-Years Warranty]

This is not only great to have going overseas with your 110v appliances, it's great for using those 220v appliances in the US. Ws so good, we bought a 2nd one to cover all our electrical transformer needs. Doesn't use a lot of power when is use, but suggest you leave it unplugged when not in use.

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.

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.

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.

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.

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 device is terrible. I brought it overseas to convert the current for my sauna blanket and tired to plug in a a small light. Initially the things worked but the sauna blanket didn't seem to be beating like usual so I unplugged it and plugged it back in, at which point the machine gave me a very scary shock. Then, my device would not even turn on so it effectively almost electrocuted me and broke a very expensive electric device. Do not recommend.

I recently moved from Italy, and brought music equipment with me. I can use my equipment without loss of audio quality.
