500W 110V/220V Step Up&Down Voltage Converter Transformer | 110V to 220V OR 220V to 110V, US Power Cord, Circuit Breaker Protection, Power Converter

I actually purchased a 2000W transformer from Yinleader initially, after moving from Europe back to the States, to support certain appliances. One of which required 1500W power supply, so I thought, without reading enough about the product, that 2000W would cover my needs. After a few months, the transformer began to fail sporadically, and mostly stopped working after about 5 months. I contacted their tech support to see if there were any suggestions (I wasn't hopeful, because I was outside the return and the support windows, both.) Huang in Tech Support, however, answered immediately, explaining that they strongly recommend purchasing a transformer that supplies at least 2x your power requirements, and included the snapshot of their product recommendations. That meant it was my fault that I burned out the first transformer. Instead of leaving it at that, however, which they had the right to do, Huang offered to refund me the first purchase if I was interested in paying the cost difference to the higher 3000W model that I needed. Obviously, that is exactly what I was interested in, and so I took the offer, purchased the new model, got a refund immediately, and am powering all of my appliances again, but correctly this time! Thank you to Yinleader - both making a great product and also standing behind it.

This is both convert from 110 to 220 and from 220 to 110. It is very useful.

”¡Excelente compra! Superó mis expectativas. Tiene muy buena calidad, es fácil de usar y cumple exactamente con lo que promete. Llegó en perfectas condiciones y antes de lo esperado. Sin duda lo volvería a comprar y lo recomiendo al 100%.”

Item stopped working after 8 months of use, all while following the manufacturer's instructions. Contacted Yinleader looking for a replacement/warranty replacement, haven't heard anything yet. Will update if and when we get in touch with Yinleader.

Much quiet than my old one , it is heavy make me feeling a wel-built quality but after an hour, it feels warm from it

Bueno

I needed more 220V power at work, but I only had one outlet. This unit to the rescue! Dual 220/240 AND dual 110/120V outlets, with a power input selector switch on the back, has done what I need! I was able to plug into my 220V line, set the inverter to 220V input, and power both ends of my 220V cabinet, instead of having one side doing all the work and creating a nasty whistling noise any time I open the door! Definitely useful for anything, and it basically works anywhere (excepting maybe some parts of Japan which still run on a flat 100V) so if you need power split or converted, this is your device!

I have two of these transformers , I have been using them for almost a year and they work fine , they are small, silent and do not get warm . I recommend these transformers without hesitation.

Worked for 2 years perfectly, then the switch between 110/220 started to give issues and blew the fuse on the coffee machine. Now it’s hit and miss if it works.

Me funciona correctamente durante 24 h con una TV de 72" , aparato de TV satelital , aparato Megacable y wiffi y recarga de celular

Muy buen producto en tiempo
