Great price and does exactly what I need it to do

Pedí este producto porque tengo unos aparatos japoneses que utilizan 100 volts y me funcionó de maravilla!! Muy recomendable

Opened the box and the fuse inside was blown. No backup fuses supplied. No instructions. Looks like cheap Chinese quality. Dead on arrival.

Solo lo use dos meses y ya no funciona, para colmo no hay garantía de este producto

I am using this transformer to replace the rice polisher I bought from Japan because of the difference in voltage.I have been using this transformer for over a year.

Great for use of low-wattage Japanese-domestic electronics on US 120v AC outlets, without having to worry about burning out the circuit board. Works perfectly with my Technics SU-A6 MKII pre-amp from Japan.

Muy útil y de buena calidad en su construcción. Cumple al 100% con la descripción.

Lo compré para una Dyson japonesa.Encendió la plancha un par de segundos y ya no funcionaba el convertidor.

Es tal cual funciona al 100% sin falla

Probé con medidor de voltaje y hace bien su función. Silencioso

Tal vez sea subjetivo, pero escucho más limpio el sonido en mis dos aparatos de 100v que antes conectaba directo a 120v

Ok so, check it. I play a Japan based Mobile crane game called Toreba and, ended up winning a bunch of stuff up to and, including Small Appliances all of which are the Japan standard of using 100 Volts instead of the American standard of 110-120 Volts. The reason why I ended up buying a couple of the 1000 Watt rated boxes(One for the computer area and, one for the Kitchen.I'll add that story too) is because one of the many items that I had won from Toreba was a single person Sandwich Maker. you know, the kind that cuts the sandwich diagonally as it grills it. Anyway, I loved this thing and, would often take it to work with me just so I could make something quick in like 5 minutes time and, then back to it. (Lots of outdoor kind of work) But, one night I noticed that the top part wasn't heating as much and, the bottom section was scorching my bread so I knew it was probably about to out and, sure enough It quit later that night. I opened it up and, all the wiring all looked intact and, everything but, I guess the elements just burned out. So I admitted defeat and, knew that I brought this on myself because I knew that it would happen eventually, I just didn't know that it would happen that quickly (like a month and a half of use) but, I did get some fair bit of use out of it.Now for the story of the Prior-mentioned Kitchen placed box. My wife's coffee pot had stopped work properly and, she needed another one but as luck would have it, I had also won a coffee maker from Toreba as well. Again, it was a Japan standard 100 V unit. So she tried it out and, it worked great but, she mentioned to me that it was kind of difficult to turn it off at the switch(located on the back) because the unit was fairly hot to the touch. Again I chalked it up to Over-volting. I knew that I didn't want to burn out the coffee maker just as quickly as I did the Sandwich Maker so I starting looking for converters to lower the voltage and, after a little bit of searching, landed on these units here. After looking at a fair amount of the small appliances that I had won, I had see that none of the Watts had gone over 750 so I bought a couple of the 1000 Watt rated unit to give myself a little wiggle room.So after they arrived, I plugged one into the kitchen and, then her 100V coffee pot into it for her to try the next morning and, the result was instantaneous. It brewed her coffee and, she reported that the coffee pot wasn't too hot to the touch anymore to be able to turn it off. Ok cool, mission accomplished. Even now as I'm writing this, I'm using the Step down unit in tandem with a small 23cm wide electric grill 100V at my computer desk for a small meal. It really does work wonders and, was totally worth the buy. In fact, if I might even end up buying a third to take with me to work so I can use some my small appliances at work to make a quick meal and, back to it.If you have any plans of traveling to a place that has a 100V standard or you happen to have small appliances that use it, I would highly recommend this.Now, on the other hand, I haven't tested out the 120V option yet because I haven't had a reason to yet since I can just plug things into a normal outlet.Thank You for your time.

Muy útil, llegó antes de lo esperado, solo que llegó algo golpeado pero funciona correctamente. Deberían mencionar que puede requerir un adaptador para conectarse o incluirlo en el producto.
