## Description

120V to 100V Voltage Converter 1600watts Step Down toroidal Voltage Converter for Japan appliances Used in US［CE, CQC Certified］ - desertcart.com

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

## Questions & Answers

**Q: Would  this be  safe to use with a 100V 50/60hz 900w rice cooker? I read that I may need double the recommended 900w on the rice cooker?**
A: This converter allows maximum 1600W. I'm using this for a digital controlled toaster oven (100V, max 1350W) for a while and there has been no issue. Electrical devices such as motors require more power than steady-state power consumption because of the large current flow at startup. Rice cookers are heaters, so I don't think you need to worry about this issue.

**Q: Do you make one with a higher wattage capacity? My Japanese rice cooker uses 1850W.**
A: We have a plan to manufacture converters with higher wattage capacity that use Japan appliances in US or CA. But it need time. R&D and test and test and test... :)

There also have some other brands of converters on Amazon. Hope that would meet your need and help you enjoy your life with the rice cooker in US.

Any other questions about step up/down converters please feel free to contact us. We will get back to you asap. Thanks for your trust!

**Q: Just to be 100% clear, umisound, the highest operating temperature is 105 celsius? or 105 fahrenheit?**
A: 105 celsius. Kindly be noted that keep away from it if you feel hot.  For continuous use over 2 hours, the max power 900W is recommended.

**Q: what are the safe operating temperatures for the 1800W model?**
A: 105 degree. Recommend using the 1800W step down voltage 120v to 100v converter with Japanese appliance which has rated power below 1500W. If you need to use the voltage converter continuously over 2 hours, the power consumption of appliance should be less than 900W. And do not touch the shell if you find it is hot.
