T-5000 5000-Watt Voltage Converter Transformer - Step Up/Down - 110V/220V - Circuit Breaker Protection [3-Years Warranty] (5000W)

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.

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'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?

I bought a few transformers when I moved from the US to Australia. This one I've been using in the kitchen and it has done a great job powering all my US applicances that I brought over with me including a Cuisinart, Instant Pot, electric knife, etc. A lot of these units make a humming sound sometimes, but this one does not.The only downside to this unit is the extra 220V socket. Seemed like a good idea to have that until my wife plugged one of our US applicances into that socket by accident and fried the device.

Does NOT convert from 220 to 110v! There is no safe way to provide 220v input to this unit. DO NOT BUY

It's probably slightly overkill for my machine but it's better to have too much 'ceiling' to spare with this sort of application/device.[General rule with these devices: If its rated 5000W, it's probably only good for supporting a 2000W appliance consistently, perhaps a bit more at 'peak', but don't push it.]Pros: Well built, circuit breaker on back, good connectivity options.Cons: Ugly behemoth of a machine... but it was that or buy a new coffee machine when we moved to the US.I have a couple of the nicer-looking white Nisorpa 2000W jobs for low power devices. They have the advantage in the looks department but can't handle high wattage applications.

This is a great transformer for my European coffee maker (220V). I've had this for about 18 months and has worked well for me. I bought this 5,000 W transformer because I read from reviews that coffee makers draw an enormous amount of amperage when starting. Although the coffee maker says 1875W requirement, I wanted to be on the safe side.After 18 months, the transformer still works well and my coffee maker still works well.I like that there is a 220V outlet and two 110V outlets and a switch in the back. I like this product and would recommend it for any step down power requirements.
