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.

This UMI converter does what it says: it changes 110v to 220v for using bigger appliances overseas. It feels solid and hasn’t given me any trouble so far. It’s a bit heavy, but it gets the job done.

Excelente transformador. Fácil de usar, durable y ocupa poco espacio. Para usar productos que vienen de fábrica a 220 en geografías con 110.

1 star less because of the price and size. If smaller and cheaper it would definitely be 5*

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.

Decent step up inverter, perfect solution to use with a 110V outlet available to convert into 220v. Currently still using it with a 60Hz device, ~700Watt, had an incident where my device went overheating after turning on this converter, but not sure because of what. Pretty easy to use, plug (input) into a 110v outlet, get two 220v plugable (outputs) on each side of the converter. Worth the cost, does not overheat on its own after ~2 hours of continuous work, not too heavy considering the copper coils inside. Recommending it so far, after using it for a few months.

This produces works perfectly for my European Dyson Airwrap while I’m using it in Canada. While it is really heavy (+10 pounds), it does look sleek and not too bulky and it is super simple to use. Would recommend if you want to use your EU dyson products (240V vs 110V) in countries that don’t have the right voltage.

Update 7 Jan 2023:Still no change in item function. Since the original review (below), I tried to contact the seller via Amazon...no return message. I tried to contact the seller via the email provided in the product manual (umi-30@umipower.cn)...no response. The phone number in the product manual is a foreign phone number in China (country code +86). The warranty card that came with the item says it has a 3 year warranty, but the seller's website (umivc.com) only says 2 years AND the buyer must pay all shipping charges but doesn't say to where (China?). No further information given. The contact number on the seller's website is a foreign phone number. Seller does not provide another way of contacting them. Through this experience, the seller has made it very clear to me that they will NOT stand by their product and have no intention of honoring the warranty. They provide conflicting information on warranty and repair, and have refused to communicate with me. I changed my rating to 1 star because of this experience.Original Review, Oct 2022:This product (1600W) was purchased in Jul 2020 and worked flawlessly for a little over 2 years, allowing me to use my Italian espresso machine in the US. Absolutely no issues, with excess power available (I bought much bigger W than required). It is very quiet, and looks respectable on the kitchen counter. Then, 2 weeks ago, without any warning or obvious issue, the item just turned off. The espresso machine was plugged in, but not turned on at the time. I unplugged the espresso machine and the converter turns on, then turns off almost immediately with no external load, no warning sounds or no abnormal screen indications. I changed kitchen outlets, and also tried outlets in different rooms, with no change in item performance. Other appliances function normally in my electric outlets so I can only reason the issue is with the converter. I have found no way to reach the seller for assistance or the seller to respond. Up until a few weeks ago I was very happy, 5 star, and would recommend this item. But now, I can not recommend from either a reliability or customer service perspective. I expect more, especially with no overload or abuse. I would reconsider if the seller would help me resolve the issue so I could use the item again.

I have a small upright freezer we brought from South Africa when we moved to Canada that is rated at about 200 W. This converter works like a charm and being able to monitor the output wattage on the display is a really nice feature. I also have a set of PC speakers hooked up to the second output and everything works fine. As far as I can tell the build quality is good, and it doesn't make any noise or produce that much heat. Very satisfied with this purchase.
