ELC T Series 2000 Watt Voltage Converter Transformer - Step Up/Down - 110v to 220v / 220v to 110v Power Converter - Circuit Breaker Protection, CE Certified [3-Years Warranty]

This transformer works perfectly. The big toroidal transformer surprises me in a unit at this price and may explain why this unit runs perfectly cool. The power on the 5000 watt version is sufficient to run my Vita-Mix and brew coffee (the coffee pot and blender both have high peak wattage demands) at the same time without a hitch or a hiccup. The product is silent.Keep in mind that it comes with a US style plug built in, so you will need an adapter to plug into your wall if you live outside the US. Of course, like all transformers, it does not convert the cycle rate at which the current alternates (50hz or 60hz will remain the same - transformers only change voltage).The quality and performance of this unit absolutely destroy all the other transformers around our apartment (fortunately they came with it and we didn't have to learn the expensive way).This is the no-brainer transformer if you want to ensure adequate power and excellent quality without all the noise and heat.

I have been using transformers for a while, usually for step-down purposes. This is the first transformer that is serving me as a step-up transformer. While I don't know how it operates in a step-down mode, I can say that in my case is completely and utterly silent which is extremely important to me since it is serving in my musical studio control room. Not a hum! This is the first time that I do not have to apply any, and I mean any sound treatment around it. Besides that, it is much lighter than other transformers I have (and I have or had at least a dozen of them). Two more are already in my stand-by shopping list waiting for the rest of my equipment to arrive from Europe. I cannot testify for its durability, however, since I've been using it for only a couple of weeks now. Rest assured that I will update this review should any unexpected failures happen.

Even though it says does not work with US 240VAC, that not accurate. If you have an older home like me with single phase 240VAC, it works PERFECT! I use it for my workshop because I cannot run everything on the 15A 120 circuit. I tapped into the dryer hookup on the other side of a workshop wall, and use the 5000W box to power 120VAC equipment - a 1200W portable air conditioner, and 850W dehumidifier, a 400W 3D printer, and 300W 3D printer, and an 800W 3D filament warming cabinet all at once!. If the dry er is set to MEDIUM heat (as opposed to high), the 240VAC/single phase/30A dryer breaker supports it all just fine. The unit does generate some heat, but not an alarming amount. Good idea to keep any wood, cardboard, etc. 2 feet or more away as a precaution....but it is not creating an alarming level of heat.

I've been waiting to post this review until I had thoroughly tested this converter. After all, if you're anything like me, you simply don't want to risk any electrical issues (especially when you're trying to pull a great espresso shot from your European espresso machine).I've tested this with:Solis Scala Burr Grinder - 220-230v / 180 Watts / Euro PlugDelonghi EC680M Ultra Compact 15 Bar Espresso Machine - 220-230v / 1450 Watts / Euro PlugI chose the 5000 Watt version because I had heard that while 2x the wattage should suffice, certain appliances will require an even greater buffer in order to startup fans, pumps, etc. I didn't know if this theory applied to an espresso machine, but since it's 15 bars of pressure, I wanted to play it safe.After multiple uses, I can say that I feel safe using this converter. It is solidly built, and doesn't heat up or emit any odor whatsoever. There are no issues powering my devices. I simply plug the converter into the wall, plug my espresso maker into the converter, flip the converter's power switch on, and then turn on my espresso machine.The machine is substantial in both size and weight (21 lbs), and it's not exactly a beautiful appliance you want to show off on your kitchen counter amongst your shiny chrome gadgets and stainless steel appliances. Given this, I store the converter in a drawer (it takes up half of the space), and then lug it out when I'm in the mood for espresso and grind the beans.As a converter, it's top notch. I'd buy it again in a similar situation. However, in an ideal world, I'd trade in my appliances for exact U.S. versions, not lose any money in the exchange and then never lug the converter around again. 1st world problems, right?

This device saved the day for me.I used it to power my top-end desktop PC that I shipped from overseas. It handles the pressure very well.It produces absolutely no sound, and doesn't occupy much space. Of course it's very heavy, but that's understandable.The instructions are very confusing and there is no manual. So, what you have to do is to set the red switch on the BACK to 110 and NOT to 230 for your device to work in the US. It took me some time to figure this out and I was a bit worried at first that it was not working properly.I'd suggest that you connect this to one device only. If your device doesn't require so much power, get the one with less watts. It will be much better than connecting it several devices for space and effeciveness.

So far so good~ It's very quiet when turned on (in that it doesn't making humming noise that I hear from other cheaper converters I have). You can only hear a slight humming only if you press your ears to the device (and won't hear it even if it's like 1cm away!). Very quiet!!!It's fairly heavy, but the flat profile, means it takes a bit less space. It might be nice if they actually provided a vertical mode for it (I can't turn it on its side since it has ventilation holes on the sides). It has worked well with both a rice cooker we got from Korea as well as a Samsung ML-1640K laser printer we brought from Korea as well. I also like the fact that it works in reverse, so it'll be useful if I ever decide to move to a 220v area.
