UMI 1800 Watt Voltage Converter Transformer - Heavy Duty Step Down AC 120V to 100V Power Converter - for Japan Appliances Use in US Canada Mexico – CE Certified [3-Year Warranty]

If you're going to buy a Japanese high wattage high end Amplifier or other high end audio component that runs on 100volt, you definitely need this high quality high power converter period.

Works great. Bought 2 dyson hair dryers in Japan and using in the US has been a breeze thanks to this machine!

Picked one up to convert my Makita metal shear that operates at 100v to run on the US 120v

Used for hairdryer from Japan. Works fine but its just huge and heavy. But otherwise does the job.

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.

While vacationing in Japan, my wife purchased a Panasonic Nanocare hair dryer. The hair dryer is rated for 100VAC, since that's typical house voltage in Japan. We weren't sure how well it'll work in the US household with 120VAC voltage. At home, we noticed it has an intermitten time delay when you first turned on the hair dryer. Worrying that the higher 120VAC may cause permanent damages to the hair dryer, we decided to try this 1800 watts step down voltage converter. This step down voltage converter is designed for the Japanese appliances.We couldn't be any happier with this purchase! The Panasonic hair dyer works flawlessly with this step down voltage converter.

Recently, I recieved a large Hinamatsuri celebration shrine from a friend in Okinawa. It is a very old family heirloom, and hadn't worked in a while. Aside from needing a new key, as it also was a music box, it needed two japanese shrine lights and of course, a converter box to run in America. This box converts wonderfully and allows me to leave the shrine on to illuminate March 3rd (hinamatsuri day) or any other chosen time! Sugoi!

Good!
