UMI 2000W Step Up Voltage 110v to 220v Converter, Voltage Converter 110v to 220v for Large Capacity Device Up to 4000W, Step Up Converter 110v to 220v with Pure Copper Coils- Transformer 110v to 220v

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.

Working perfectly for 220v espresso machine in USA.

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

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.

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.

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.
