Must have for Japanese appliance
Worked like a charm to convert my Japanese product to acceptable voltage. Very quiet operation.

Worth the money!
This review is after two years of daily use. I’ve been using this product everyday with my Japanese made hair dryer. It has been working pretty sturdily and has never caused any issues so far. Body design is sleek and clean: easy to wipe clean. No complaints!

Saved My Wife a Disappointment
It’s a bit heavy and bulky, but it gets the job done. It has two outlets and a digital display showing how many watts you're using. Trust me, this is extremely important—here’s why: My wife bought some Japanese appliances and was told by the store staff that they'd only work with 100V (the Japanese standard voltage). I thought it would be a great idea to buy a small travel converter to solve the issue. It did not. When we got home, the small converter overheated and shut down after 5-7 seconds. The voltage was correct, but the wattage wasn’t. (I’m not an electrician, so I didn’t check the wattage when buying the small converter.) We thought we’d bought a brick, but there was still hope. After a bit of research, I found this converter. So go ahead, buy your Japanese appliances with confidence, because this will keep you safe. Just make sure to check your appliance’s wattage—it should be LESS than what this converter can handle. If your appliance needs more power, you’ll need to buy a higher-capacity converter.

amazing product
this appliance is way better than i imagined. it gives you a live readout of the power draw in watts and we have gone up to 2000w+ on multiple appliances and it kept working great. we use this to power our japanese oven and induction range on USA power. we also plugged in our japanese hot water heater that we've been using on 120V for years and it performs so much better on the appropriate 100V! surprise benefit. the hot water heater used to surge when the heating cycle completed and would flip the breaker if there was a lot of draw on that circuit at that time. Using this stepdown converter we havent had ANY issues with any of our japanese appliances.

Nice design
Nice design, does not take up to much space, I like the on/off button. Works as designed.

Vintage Japanese HiFi (unlocked)
Purchased this to use with my vintage Japan-only Yamaha turntable (YP-511). Works great. It hasn’t indicated to me the wattage usage it just shows 0 on the display but this is likely due to the turntables very low wattage (something like 3w if I recall). What matters most to me is that the current coming through this is correct. I’ve tested with a meter and it is accurate so I’m a happy camper. This model might seem like overkill for 3w but I do intend to purchase a set of Japan-only speakers and amplifiers that I would also plug-in. Also of note, I received an email from this company inquiring whether or not I had any questions or concerns about the product so I feel like there’s a certain level of assurance that the company would stand behind their product. So overall I am content and felt like this was a great purchase.

Must have
So glad I got this, a must have with a Kotatsu table. The price was decent, no bad smell, took me a moment to find the cord in the box but I did. I turn it off at night which is a button on the front.

Cualquier electrodoméstico japones (incluido cualquier producto Dyson) funciona a la perfección. Yo específicamente la compre por que me traje una Dyson Supersonic de Japón. Llevaba tiempo sin poder usarla desde que volví, ya había probado con 3 aparatos mas que recomendaban en TikTok pero la verdad solo perdía mi dinero. Este producto fue la ultima oportunidad que le daba al tema de la Dyson y la verdad fue un gran acierto, funciona perfectamente!

We bought a high-end rice cooker in Japan, but were dismayed when we got it home and it kept erroring. We read that some newer electronics are sensitive to voltage ranges so bought this unit and we are so glad we did! After running the rice cooker through it, we have had zero problems and perfect rice every time. The readout even shows power consumption so you can see how much your appliance is drawing. Highly recommended, saved our rice cooker investment! Note the unit is VERY heavy and bulky (about the size of a toaster) so this is not for travel!

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.
