LVYUAN Voltage Converter Transformer 1500 Watt Step Up/Down Convert from 110V-120V to 220V-240Vt and from 220V-240V to 110V-120V with 2 US outlets, 2 Universal outlets, Resettable Circuit Breaker

Good piece of equipment. I bought an all-in-one brewing system that is built for use overseas. The plug was mismatched to the US standard plug, and the voltage was different. Plugged it in, plugged it into the US-compatible socket, and set the step-up voltage. Everything was working fine. The heating element, the recirculation pump, and the controller all worked fine.

Great product.

Works great! Bought it to run an Indian wet grinder - Ultra 2.5L (150W , 230V with a 250V 6 Amps rated plug). Runs perfect as this has plenty of power: 1500W (just in case to use with a 1000W Indian mixer grinder in future) For 120V input, gives 241V to 245V output, so beware if your device is sensitive to small increases in voltage. I was skeptical about accidentally flipping the input voltage switch on the back, but it is well designed - no issues. No noise and seems like well built overall. No complaints far, but wouldn't mind giving some extra bucks for a display that shows input volts and output volts and watts. Design may be enhanced to hang over a wall.

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.

I purchase this unit to power one Korean made rice cooker and it died. Then I got a second one and the same thing happen. This is a poor quality product and I recommend a different brand.

UPDATE: seller replaced item and it's working now. Will update if it fails again. way under specced. This worked fine for a few weeks, but now it fails after about 30 minutes of sustaining a 130 watt load (a small hvac blower). Yes, the product listing states you should size up 3x for running a fan motor, which we did. E.G. they say 1500 watts rating is required for a 500 watt motor. But our motor only draws 130 watts. You can do the math, but that's way less than 500 watts. Also, it fails while the fan is running, not during start-up, when the 3x extra capacity is supposedly required.

Works great.

Works great … good unit

Funciona muy bien y me parece perfecto el como tiene dos niveles de enchufe a 110 y 220v

It was enlightening to once again fire up my AEG 2EA 450W, 240V percussion / hammer drill after 40+ years. Still in the box and the drill in great shape. I had tried using a modern cordless and drill into my outside brick wall and failed. Purchasing the LVYUAN Transformer 1500, best deal ever. Used concrete bits of course and within 30 seconds had a 1" hole for the screw and insert. That drill is built for hammering, period. The Transformer didn't flinch. Even though the HZ frequency is different, this will have no adverse affects on this drill. (although may not be suitable for sensitive electronic equipment)? Would research that. Cool, silent, green light all the way. A great investment.

Works flawlessly,fast delivery

El producto parecía resistente y de buena calidad pero el primero que compré dejó de funcionar en menos de 10 meses. Compré un segundo nuevo bajo trato con el vendedor en vez de aplicar una garantía en el primer producto e igual dejó de funcionar en menos de 4 meses. La garantía ofrecida por Amazon se lava las manos y responsabiliza al vendedor el primer año. Nada recomendable, no comprar.

After 7 months, it stopped working. The green light is on, but none of the devices turn on. I used it no more than once a week, so I think a device like this should last longer. I tried contacting the seller about the warranty, but I didn't get a response. I don't recommend this device. I'm very upset that I wasted my money on it.
