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.

Excellent product, with a slim design that looks nice in the kitchen.

does its job perfectly, I'm using it to power a roborock vacuum robot base station.

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.

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.

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.

Working perfectly for 220v espresso machine in USA.
