LVYUAN 5000 Watt Voltage Converter Transformer Heavy Duty Step Up/Down AC 110V/120V/220V/240V Power Converter with 3 US Outlets, 3 Universal Outlets, Resettable Circuit Breaker Protection

Excellent product and very well made! It works perfectly and allows Step Up / Step Down from either 220-240V AC 50Hz to 110-120V AC 60HZ or from 110-120V AC 60Hz to 220-240V AC 50Hz. Extremely happy with this product as it does exactly as advertised and if you require a Step Up / Step Down Transformer this is one of the best quality units on the market at a very reasonable price.

I bought it to use my Dyson Airwrap in the US. I bought the airwrap in Korea and needed to convert the electric power. It works very well, no noise at all. Also, easy to use! cord is a bit loose.

Works well with my vintage Singer 431G which is on UK power. Very quiet and runs smooth.

EDITED REVIEW 1 star to 4 stars.Initial Review:Transformer only worked for just over 2 months. Attempted to contact the manufacturer using the warranty link on Amazon with no response or reply after a month and multiple attempts. Terrible customer service with little chance of getting assistance through Amazon. Do not recommend.Updated Review:After posting my 1 star review the company reached out to me to rectify my warranty issue. Within 24 hours of notifying the customer service representative Bruce of my defective transformer, he had a new one shipped to my address which arrived within 48 hours. The new transformer is working as advertised. Amended review to 4 stars.

A great product. Indeed i can express that as a first time customer I am truly satisfied. The manufacturer did a Good job and for which must be commended. Therefore I deem it safe to give this product a 5/5 star ratings.

As someone else already mentioned, the European plugs don’t fit properly—they sit loose in the socket and tend to fall out.I managed to get it working briefly with a blender I brought from Germany, but when I switched over to a lamp, things went south fast. The transformer made strange noises, the light flickered for about 30 seconds, and then—boom—the main fuse in my house blew, and everything shut down. This is a cheap piece of junk. Poorly built, potentially dangerous.

Works well

I bought this voltage converter almost a year ago to use a 220V hair dryer without buying a 110V one. I only use it for a few minutes when drying my hair, and in my experience, it converts the voltage stably; it works well for that occasional use. As an improvement, I would like it to include small displays showing the input and output voltage, and some internal status information for informational purposes. Otherwise, it's done its job so far in my case.
