UMI 110V to 220V Step Up Voltage Converter 500W for Europe China Korea 220V-240V Appliances Use in US Canada Mexico -Circuit Breaker Protection and Overheating Overload Protection [3-Years Warranty]

Based on other reviews, I bought this to be able to use a UK-model Sony "bookshelf" stereo here in the US. It's been in continuous operation back in my workroom for about 7 months now, with the stereo running for several hours a day (I listen to it a lot while working), and I'm well-pleased with its performance. It runs cool and quiet -- of course, I doubt the stereo is really taxing the wattage limit of this unit, either -- and doesn't appear to emit any significant amount of RF interference since the stereo has no problem receiving even AM stations despite the transformer sitting less than a foot away from it.I also like the fact that some thought was put into its external appearance so that it blends in with the rest of your TV and stereo gear, instead of being a chunky, industrial-looking black metal box like most other transformers of this type. If I acquire any more vintage UK or European stereo gear in need of a similar step-up transformer, I'll definitely buy one of these again!

Bought a product from India and have been using this transformer for about 6 months. Works well and is built well.

Strong build. Heavy stuff! Lots of wiring inside i guess. Used it to power a 220 v video projector. Stable performance without any glitches whatsoever,

When I ordered this item I was not sceptical. I need to power up European version of Thrustmaster T300 RS GT racing wheel in US. So I'm decided to buy this 500W 110v to 220v converter. The item is surprisingly heavy for it's small size. Also it works really quiet. First test passed, racing wheel is not fried and I'm happy about it! Hope this converter will work for me for a long time.

It does its job, stable and no noise. The design looks good compare to other similar transformers. It’s quite heavy though, I can’t think of any one would bring it along when traveling.I like the product so far, two feedback for further improvement:1. Make a black color version, it matches dark color furniture better2. Make it even smallerOverall, I don’t have any complaints

Perfect at doing the job and fits into lounge without looking too bulky.Value for money and great buy.

Initially had a concern about an alternating internal buzzing and Amazon replaced no questions. Replacement arrived only to do the same thing. Tech support contacted me and they confirmed issue is because printer when powered on in an idle state, connected will send reverse electrical waves causing the units internal coils to vibrate, assuring this is not anything dangerous. So far, no issues and still happy with product.

Transformer is perfect for 220v to 110v
