Goldsource 500W Voltage Transformer Converter (110V to 220V, 220V to 110V) Step Up/Down Power Converter 110/120 Volt - 220/230 Volt w/ 5V USB Output & Circuit Breaker Protection, 500 Watt (STU-500)

Never thought I'd ever need a voltage transformer. I mean, most electronics support universal voltage these days right? Well, Xbox One apparently doesn't. My roommate brought his Xbox One from Europe, and it couldn't run properly here. After some research, I think we need a transformer. There are cheaper options out there for sure, but for electricals, quality, stability and durability are always the most important. So we chose this one as it seems to have a long history of reputation, and a reasonable price. The product came in with a nice compact look. A bit heavy, but we aren't throwing it around anyway. Some reviews complained about the smell, but I think it is not that bad, why would you keep a transformer around your face? Operating it was pretty straightforward, select the voltage on the back at 110V, plug it in, plug the Xbox in the 220V Universal outlet, turn the transformer on, turn the Xbox on, AND IT WORKS! Till today we have been using it for 3 months now, and it never failed us. We sometimes also used it for my small mixer from China (rated at 250W) and it also worked perfectly. Do pay attention to the suggested wattage though, a 500W transformer doesn't mean it can run 500W appliance, as electronics tend to have a voltage spike when turned on. Some common sense from an engineering student :) There are spare fuses, so you still have a second (and a third) chance. Overall I would recommend this product.

Why I needed a transformer... because I was stupid enough to buy a Tommee Tippee electric steam steriliser from an ebay seller from UK -- that's how they spell their sterilizer btw. I didn't think about the fact that the plug *might* be different or that the voltage needed would be more than standard US voltage. I blame the brain fart on my pregnancy. I had a universal plug adaptor, but I was scared that the sterIlizer wont sterilize my items at all due to the lower voltage. So I bought this handy dandy transformer... which I wouldn't have needed to buy if I just bought a US version of this thing. *grumble*mutter*mutter* I was so scared to turn mine on when it arrived due to other reviews stating that theirs smoked up and smelled or made weird noises. So I followed the instructions.. behind the transformer is a small little plug like thingy (like a key kinda or pin) and you basically place it on whatever hole you needed as voltage. I placed it on the two holes that was for 110, plugged it in my outlet, then plugged my sterilizer on the transformer outlet that says 220 output (the larger outlet on the right) then I wore my rubber gloves (yes, I even turned mine on wearing rubber gloves), flipped the red switch and VOILA!! ITS ALIVE!!! Bwahahaha! My transformer was very quiet.. Didn't even hear a hum.. I even placed my hand on top of the thing (after making sure I won't get electrocuted) and I didn't even feel any slight vibration. I do think that the burning and smoking and loud noises might be due to other people buying a lower wattage transformer that couldn't handle the item's required wattage to perform. I was about to buy the cheapest transformer (same brand) until I read about the wattage thing. I admit it floored me... I didn't know what it was talking about. I didn't even know about voltage, people and now I have to learn wattage too?? Anyway, Just look either behind or below your equipment and it should tell you how much watts your equipment needs. Mine was 650 by the way.. According to the details on this thing, you have to multiple your wattage needed by 1.5 and that's the transformer you should buy. Well if I went with that, then I have to shell out more money to get the 1000 watts transformer instead *grumble* I should have really just freaking bought the US version *grumble*mutter* and as I said, it worked well with the 750 watts.. I don't think I'll be using it for other appliances at my place anyway but if you plan on double plugging this thing with different appliances then just add up the watts needed. Oh yea, it also comes with another plug thing and a small ziplock that contains two small cylindrical light bulb looking things. You might miss the small ziplock if you're opening the box. I dunno what the bulbs are for. ONLY CON: Short Cord. What's up with that?

It's a little tough for me to rate this, because whether it "works" or not for your purposes depends on what those purposes are. I need a transformer for a subwoofer built for the EU. This transformer does exactly what I need to it do electronically, providing the proper power to the speaker and eliminating the dreadful POP heard when it goes to sleep or wakes up (it's a Genelec F One), but it's unusable for a hi-fi situation because it hums very loudly. For me, it's a return. If I needed it to power something like a French circular saw, then sure, it's great.

Just received this Gold Source 750 step up/down voltage transformer converter and it came in a very good package without any damages. I ordered this to use it with a 220 V Indian table-top wet grinder: Ultra Grind +. The transformer is small in size but little heavy. It is a nicely finished Chinese product and build quality appears good. Just like the other reviewers had said, has a little kerosene like paint smell to it that disappears after some time, when taken out of its box. It is very quiet with no noise or hum during operation and comes with a small instruction paper, two fuses and a plug adapter. So far so good, works fine with no issues. Don't know yet how long will the grinder last since it's designed to run on 220 V, 50Hz frequency whereas it's being made to run on 110 V, 60Hz. This transformer is perfect to convert and run the 220 V Indian Grinders & Mixies on 110 V here in the US. The best bet though is to always bring in or buy the 110 V, 60Hz version of the Indian kitchen appliances rather than use it with a voltage step up/down transformer converter.

I moved to the US from the UK, and took my PS3 and some other small electrical items with me. The PS3 won't work with a simple plug adaptor (the green light came on, but nothing happened), so I found out that I needed a voltage transformer. I bought this size (750W) because it has enough voltage to spare (apparently this is recommended). The unit is smaller than I expected - I plugged it into the mains, plugged the PS3 into the UK power socket on the front, switched it on, and it all works I leave it on for a few hours at a time and it runs very quietly (a very faint hum). I left it on overnight once while the PS3 downloaded content, and it was still running fine in the morning. We have also used this with a food mixer we brought over from the UK. Instructions were very clear - when it arrived I had to set it to transform from 110 to 240 - it was a simple matter of moving a pin on the back of the box. It also came with 2 spare fuses UPDATE - TWO YEARS LATER This is still running really well. We switch it on every morning and then off again at night, but I don't think that's really necessary. If the house is absolutely silent you can notice a slight hum from this unit but otherwise no complaints. The UK PS3 is still using it every day as is our UK wireless router.

Goldsource® Step Up and Down Voltage Converter Transformer ST500 - Transformer - AC 110/220 V - 500 Watt I purchased the product because I had to take a trip to China and needed something to charge my electronics. When I arrived in China, the fuses kept on burning out when I tried to use the converter. I got an electrician at the hotel to help me out and he said that the problem wasn't the fuses, rather the product was poorly made and didn't work properly. He was shocked that a brand new product from the US would not work until he realized that the product was made in China. The electrician then added that the products for converters coming out of China are terrible. He recommended me to purchase converters from the US as they have better quality products. I guess I will know the next time around! Luckily for me, the hotel had a converter for me to use. Since I live in the US, there was no way that I knew of to test the converter until I got to a foreign country. If I had to do it all over again, I would spend a little bit more money and make sure to purchase a converter manufactured in the US. These things are heavy and a pain to drag around so if you're staying at a hotel that has a lot of American tourists, they may have one already.

[09/15/2015] i have this transformer for more than 2 years now, it works perfectly i brought a TV and Home teather from europe when i move in 2013 and that was the reason i bought it, i still have them, and use it daily, the smell has gone away in the first 6 months. i connect a power surge to the transformer and i connect now the TV, Home theater, my cordless 18-volt drill and 1 set of Ikea Lights, it works very fine with any issue, it has a 5V USB connector but i never use it, you can connect all europe connectors no problem at all and argentina, chile also. i really recommended, never burn the fuse either. some recommendations: 1. check your equipment Watts before buying, 2. don't overload. 3. it is not lightweight. [04/26/13] the Transformer works fine just the paint is really smelly but then it loss that hard smell, for the rest is perfect for what i needed for.

The unit is not designed for frequent traveling but is an excellent companion to have when staying somewhere long term and it's small enough to load into luggage if you're okay with the added weight. I had an upcoming extended trip wanting to bring my coffee pot so I chose the 500W unit. The unit powered my laptop, multiple smaller devices and even a small coffee pot simultaneously through a power strip, it also ran a rice cooker and xbox 360 without issue. The USB port was convenient but had a difficult time maintaining the higher amperage ratings for fast charging on some devices. Other 'travel' optimized transformers in this price range are more convenient but you usually wind up with a lower wattage rating. My only note is that users need to verify the actual supply voltage from the host country, there are multiple jumper settings on the back and it's important to ensure the jumper is set on the correct voltage.

所詮アメリカ向けの商品なので、110V仕様、出力は10％低い200V。何に使えるのか？
