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)

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?

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.

I have been using this voltage converter since 2 years. Not a single complaint from my end. Compact design, well built and safe . I have indian grinder and power converter is the ideal one, functionality - no issues at all.

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.

I bought this for a pre-owned Germany vintage stereo collection. Seller was kind enough to tell me that it only works on EU 230V so I need a voltage converter for US 110V. He also recommend this brand that he’s been using since 2019, which I’m glad I listened. Compact size, very sturdy product, works perfectly since I received them!

Goldsource® Step Up and Down Voltage Converter Transformer ST500 - Transformer - AC 110/220 V - 500 WattI 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.
