Yinleader 1000W Voltage Converter Transformer(110V to 220V OR 220V to 110V) 1000 Watt Step Up/Down Converter 110/120 Volt - 220/240 Volt w/US Power Cord,Circuit Breaker Protection (VTUS-1000)

Works for my 220V Juki sewing machine, no problem.

Works great. I almost use it everyday.

Yes, yes I did. And this thing does exactly what it says it will. I use it specifically because my 15 watt tube amplifier only runs on 220V and I live in the US. Why do I like it? Because it doesn't impart any noise to the electrical signal. Just me and my amp and all that bad sound is all me. The good sounds are too but if the concern is funky humming or introducing odd noises into circuits that produce noises, this thing is quiet. The "ideas" section says I should comment on its weight. It's light. But if I was a little kid it would be heavy. Just read the item description and make you own judgment. Also, even after running for a long time during practice sessions, it doesn't get hot. So that's also nice in a room full of active electronics.

For now it does its job.

it doing well.

I purchased this 110V to 220V voltage transformer approximately 1 year and 5 months ago. Over this period, I used it roughly 20 times total—not heavy usage by any means. Unfortunately, it has now completely stopped working; no power output at all. While it did function properly during the limited time I used it, I expected much better durability given the light usage. 20 uses over 17 months translates to barely more than once per month, so this failure feels premature and disappointing.

I previously purchased three of the 500W models, and they work perfectly for smaller appliances. One unit did malfunction, but the company replaced it at no cost, so I was happy with their customer service. When it came to our water dispenser, though, I opted for the more powerful 1000W version. It’s been connected 24/7 and performs flawlessly. If you’re planning to use these for larger appliances, such as subwoofers, refrigerators, or anything similar, I highly recommend going with the 1000W version instead of the 500W. It’s better suited for the job, feels more robust, and doesn’t trip the fuse as often. Koorosh

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.

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

Bought this item to be able to use my items i brought from Philippines like our nebulizer because it is operated with 220v only (not auto volt item)

Para el trabajo

Es una pena, había leído muy buenas opiniones pero en mi caso, se calienta muchísimo el aparato y solo tengo conectada una estufa de 220.
