120V to 100V Voltage Converter 500watts Step Down toroidal Voltage Converter for Japan appliances Used in US［CE, CQC Certified］

Worked great on my Yamaha CX-A5100 preamp processor from Japan. I measured the voltage and power associated with this device. Very accurate voltage and efficient. Runs cool and looks to be built well.

I bought this converter to help me safely run the Japanese Sega Saturn I bought last year. (I read online that a converter technically isn't needed as the PSU and the PCB are rated for both JP and US voltage, but I didn't want to take the chance. And I own other Japanese consoles I don't want to risk damaging.) It works flawlessly, silently, looks nice, and is a solid piece of hardware. It's exactly what I needed for my Japanese console. I'm happy with my purchase.

Got it to use with my Japanese CD player. Works great.

Has worked excellently from the day I plugged it in a little over a year ago. Zero noise, hides well in a room being white, haven't run into any issues at all. Has run all of my Japanese audio video equipment without introducing any feedback or issues at all. Best inverter I can find or ask for for the money.

Works really well, looks really good. Paired with a high end Luxman turntable and have had no issues with it. Would buy again!

They didn't ship it right away. It took way longer than the other brand I bought at the same time. This product looks good enough to put it out in the living room. (Wife won't kill you LOL) This one is 500W unit and very quiet and does not put out much heat. (Door phone using only 15W at most)

I’ve been an audio fanatic/critic for decades. Bought this to run a vintage Yamaha YP-D51 (still a hidden gem on eBay from Japan and near-mint examples are still under $500USD) turntable. It’s wattage rating is way overkill for that application but for about $20.00 more than a 100W, this 500W, 120V-> 100V step-down transformer will never be pushed for audio applications such as this. No noticeable noise, hum or heat, fast shipping.

Exactly as described.

I bought this a few weeks ago to power a Japanese HD VCR which only accepts 100V. I checked the output with a multimeter and it shows 99.7V, and the VCR is working happily so far. I can't see what's inside but it's quite heavy, the exterior design is nice, and I don't have any problem with the cable staying in the power outlets as the outlet is very tight and takes a bit of force to get the cable into. If it continues working I'll be very happy with it.

She is rather large and heavy, but works fine. Very well built and sturdy. No complaints!

Extremely easy to use right out of the box, has two outlets. Although it is on the heavy side, it’s not really meant to be moved around once placed near an outlet.

I bought this to power a Japanese minidisc player. It is very well built and a linear power supply. There is no noise on the analog side and its hefty weights a fair bit. The unit and packaging is very well done it almost reminds me of a product from Eversolo or something. I would recommend this as a great option for any japanese audio products in North America.

Everything in the manual was for a step-up adapter for 220v appliances instead of a step-down adapter like I got. Otherwise works great. Used a voltmetre and found it gives 112-114v which is well within tolerance.
