Umi 800W step up voltage converter

I have been using this voltage converter for about a week, and so far it has performed very well and met all of my expectations. I own several electronic devices that only support 220–240V, so a reliable converter is essential. One feature I really appreciate is the small LED display, which shows the current voltage and wattage in real time. This makes it easy to ensure I’m not exceeding the 2000W limit—something that would otherwise be difficult to estimate. While I can’t yet speak to long-term durability, the build quality feels solid, and with the Black Friday discount, I believe it offers great value for the price. It provides more than enough power for my needs, and I doubt I’ll ever come close to the maximum capacity. It is on the heavier side—not so heavy that it requires two hands, but heavier than I expected to lift comfortably with one hand. For anyone using electronics from Europe or Asia, I highly recommend this product. I did see a few reviews mentioning failures after a year or two of use, so I will monitor its performance over time. If I encounter issues, I may update my rating accordingly. I’ll keep you posted.

It’s perfect for my application, best transformer I’ve ever bought. It’s quiet, sleek looking, good size, and the display of power consumption is a nice feature. I also like the simple on/off pushbutton on the top. It’s been working well for my automatic coffee machine which I use daily and occasionally use it to power other small appliances. Note that the overload protection is only useful if you correctly size the transformer for a single load/appliance. I bought the 1,600W version to power my 1,500W coffee machine and works perfect. However, when I occasionally use it to power a 400W small item, the transformer provides limited or no overload protection. The transformer is heavy and feels well constructed. I wouldn’t recommend moving it around, so its better to fix it in one location on your kitchen. I’ve also noticed my transformer getting warm/hot if I leave it on for several hours, even if my coffee machine isn’t running (no load on the transformer) so I’d recommend turning it off after each use. Price is definitely on the high end but I’ve ran through 3 ugly looking, noisy, bulky transformers in the past (one actually caught on fire) and wish I had bough this one in the first place.

If you’re looking for a reliable step-up transformer to use your 220V electronics in the US(110V), this is the one! I’ve been using the UMI 2000W Step-Up Voltage Converter for about 6 months now, and it’s been working great. It handles my smaller 230V appliances as well without any issues—as long as they’re not super high wattage. The unit is a bit heavy, but the slim, clean white design helps it blend in, so it doesn’t mess with your space too much. I usually tuck it behind the TV when I’m not using it for a while. Definitely a must-have if you brought appliances from overseas and want them to work safely here in the US.

We got a coffee maker in Europe that we really like and they don't make a US-compatible version. The only way to use it in the US is with a voltage step-up transformer; i.e. convert 120V to 240V, with enough power capacity, at least 1000W. This one looks nice on your kitchen counter, unlike many industrial looking ones. It is silent, whether operating under high load or no load. The display shows the input voltage and the output power load in watts. It's a little expensive but at least in my case it was worth it. The toroidal transformer type is inherently quieter and more efficient than the older rectangular transformers made with flat plates, and it enables a thinner design too. The unit is somewhat heavy, and that is as it should be. For this type of application you want an AC transformer, not an electronic high frequency power supply. 60Hz transformers that can handle 1200W are inherently heavy. There is one dumb design issue, however it's easy to work around. The unit has two instances of what appears to be a Chinese standard outlet. The problem is that many or most European plugs do not fit it, notably the type with a big round plug and two round pins, because the pins are too large for the holes in the sockets. You have to use an adapter plug meant to adapt European outlets with smaller pins to a variety of plugs. Those are cheap and easy to find. With this, it works great.

Small, doesn't take big countertop or table... easy to use and nothing to setup.. feels great to see the power (wattage) used by any device that we connect to this 110 to 220v converter. We are using it for running some mixer grinder.

Awesome product. Works perfectly well . Needed to step up to 1200 watts from USA to european voltage and. With great success. Also comes with two outputs . Connected my coffee maker purchased in Europe from US 110 to 220 . Highly recommend this product.

Easy and Good Quality. I brought a few appliances from EU and did not think about the difference of Voltage so this was my last resort. Not expensive and value for money.

Funciona tal cual indica, yo lo compré para usar la Dyson Airwrap de 220 V y yo tengo instalación de 1120V Así que me funcionó perfecto. La recomiendo si vas a usar productos Dyson porque al encender estos equipos prenden a unos 1800 Watts
