Yinleader 110v to 220v European Voltage Converter Transformer 500W Step Up Converter 110/120 Volt to 220/230/240 Volt or Step Down 220 to 110 w/US Power Cord,Circuit Breaker Protection

I've only used this occasionally, but it works well. Relatively compact, low noise, good build quality and good price.

I actually had to order this twice as the first one had an issue with the 100V plug portion. There was a piece of bent metal that was hindering the plug to plug in.But, I decided to give it a try again and performed an exchange and all is well. I am going to chalk that one up to just a manufacturing defect which I understand does happen.Now that I have one that is fine, I will say this is a well built unit. It's heavy, and it works. I am using it for old vintage computers. I have tested a 240V European power supply from an Amiga and a MSX from Japan with 100V, and they work perfectly.500W was actually overkill for my needs, but it was cheaper to buy this with both types of connections available than buy something else.Very happy with the purchase!

Ideal for European visiting the us .For 30 usd you can get everything to work and will not have to re purchase thing ( tooth brush chager ….) however limited in the Amp ( wachout for blower or hair things that might need too stong amp) . Truely helpfull

Transformer is ok but after even a short time at work if pops the fuse because the product warms up

So I ordered a used piece of pro audio gear from Germany. I knew the unit I was receiving had an EU chord so no surprise there. I thought I would get ahead of the curve, jump on ebay and order the proper AC chord to be able to plug it in here at my house in the USA. Hmm.....not so easy. I learned a lesson here. Luckily nothing was damaged. So, just because I provided a chord that now fits in an outlet in my house in the USA, doesn't mean I provided the proper voltage required to power the unit. Plain and simple, the unit needs 230v to function properly. So no matter where I plug the unit in anywhere in any house in the USA, the unit is only getting 110v. It was behaving like a guitar pedal that needs 18v and is plugged in a 9v slot of the power supply. That's what basically tipped me off as to what the issue was...Enter Yinleader 500W Voltage Transformer Power Converter. That's it. Plugged the Yinleader 500W Voltage Transformer Power Converter into the outlet in my house and then plugged the pro audio unit with the EU chord into the coverter, turned both the converter and the unit on and it powered up properly. I couldn't have been happier. It's dead silent too. Worth every cent.

Works as expected. It feels pretty heavy, assuming its quality should be good. Hopefully it can last longer.

If you're considering this item because it's the top on your search results, scroll down a bit more. You get what you pay for, and for this price you will be the lucky owner of something that breaks within a few usages (it was a dud out the box for me, but see other similar reviews). The plugs also slip out very easily (see other similar reviews, which in hindsight I wish I'd looked at first). There is no grip at all, which is a very safe and reliable thing for, you know, conducting electrical power. Perhaps you could paint a face on it and pretend it's a robot imaginary friend, that's the most utility I can think of.

I use this step up transformer to power our European 240V scanner from our 120V mains in NA. It is silent and draws so little quiescent power that I leave it on full time. It replaced a very big, heavy and noisy transformer that had to be switched off when not in use. Very satisfied with this purchase.
