Goldsource STU-1000 Step Up/Down Voltage Transformer Converter - AC 110/220 V - 1000 Watt

The voltage transformer is heavy, sturdy and reliable. I am in Switzerland now, and I bought these for barrage of devices brought from the U.S; I plugged in a humidifier, a blender, Vonage phone, laptop, shaver (all at once), and so far no issues whatsoever.

The only catch is the wall converter from US to Euro (so that you can plug the thing into the wall jack) It is too wide for Switzerland (would work in e.g. Germany). So I had to spend a couple of euros for a converter in a local store. Other than that, no issues in the first 45 days....

Got this so I could hook up my 110v 52" LCD HDTV and LG blu-ray player here in Europe. I plugged in a power strip to the 110v outlet, and it powers both items without a hitch. Also extremely quiet. If the entire house is silent you can hear the slightest low hum but as soon as the tv comes on then it's undetectable. Very happy with this purchase and may buy another.

I moved from Germany to USA so I have a few 230V devices to run on 110V.

This converter works absolutely inconspicious.

You just turn it on, plug a german device in and it just works. No noise no hum at all.

Good product. Highly recommended.

This company back their products 100%. I had a problem with the USB power port and I mentioned it in a comment. The company reached out to me via phone and email and insisted they rectify the problem in any way I wanted. Refund or replace. I have no real use for the USB part of the transformer so elected not to have the unit replaced. Otherwise the unit works perfect. I would definitely buy from this company in the future. Excellent Customer Service!!!

I bought two cheaper converters before this one. None of them survived after 3 months. I have used this one for over a year. No problem at all so far. It is little heavy but compact in size. I used a power strip connected to this converter and have several appliance plugged in this power stip. The total power is close to 800 watts. The unit works perfectly.
