WAKA, Where did you purchase the home bakery? If you purchased it from an authorized dealer in the U.S., you do not need a transformer. There should be a label on the back or bottom of the product with the product number and specifications. If it says Volt " AC 115/120V Wattage XXX", then you can plug it directly into a wall outlet with the American voltage of 115 ～ 120 volts.

However, if you bought it from a dark vendor or an individual, or if it was sent from Japan, it may still be the Japanese voltage of 100V. Please look at the label above to judge. The Panasonic website in Japan says that the power consumption of the product is 370W, so a transformer that covers 400W-600W should be sufficient. However, please be aware that transformers themselves do not meet U.S. government safety standards for household electrical products, and therefore, all transformers on the market are, strictly speaking, illegal electrical products.

By the way, I brought a Zojirushi rice cooker (2007) and a Panasonic home bakery (2015) from Japan, and they work fine when connected directly to an outlet without a transformer.

If you are buying a transformer, the voltage （ V ） should not be tripled, but the wattage
should be higher than the voltage （ W ） 500W, so a home bakery should be around 1000W. \W By the way, home bakery consumes about W 500W, so you need to buy a 1000W class transformer to avoid burning
.

I hear rice cookers are replaced after 6-10 years.
What do you guys do ？ If it works, do you use it forever ？?

Thank you all ！
I guess it can be used without a transformer ！
On the other hand, I wonder if there are any broken ones without a transformer ？.

waka,

To tell you the truth, I am also an electrician by nature and use a transformer instead of a transformer, but there are some people on this forum who are very aggressive in their opinions, and I was "uncharacteristically" concerned about that. For the time being, I recommended the use of a transformer. Modern home appliance manufacturers design and manufacture their products to meet safety standards that allow them to withstand use in hostile environments by their consumers. I would venture to guess that they test their products to ensure that they will not catch fire even if the power supply voltage fluctuates by up to 30% over a specific period of time.

Furthermore, even in cooking with heat, such as in electric kettles, the structure is now such that heat is obtained by passing a special radio wave through a special metal, and the radio wave is controlled by an electronic circuit that can automatically control the circuit even if the power line voltage changes significantly. Therefore, there will be no problem even if you use a product with a standard AC 100V input at 120V. However, there is always a "just in case" possibility, so please keep that in mind.

Baikinman, thank you very much for your kind attention ！
Since I am bringing this from Japan, I think I will take the risk and use it as is ！ So far I have not seen any postings of people breaking without a transformer, and your advice and Baikinman's theory have convinced me. I am convinced by your advice and Baikinman's theory. Thank you ！

but if you guys have any other information, please let me know again anytime ！

Sorry to get technical again, but in the past, electric cookers such as electric kettles used electric line voltage （ 115/120 volts ） in the US directly into a heat exchange material such as nichrome wire to obtain heat output. Today, however, the heat exchange material has been replaced by the "IH （ IH ）" method.

https://www.itmedia.co.jp/fav/articles/2012/27/news021.html

This is the technical term for electric line power as mentioned above IH ＝ Induction Heating （ Induction Heating ） converts the power into heat, specifically （ the power of a high frequency ） magnet applied to an iron pot to convert it into heat power. At any rate, the power of heat is obtained in a much safer way, not by mucking around with nichrome wire as in the old days.

So, to return to the main topic, the heat return device can handle large changes in line voltage, and at the same time, the manufacturers of these electric kettles and cookers have designed and endurance tested their products so that they will not be affected by a voltage of 125V or so applied to a Japanese voltage of 100V for a long period of time. I believe that these electric kettles and cookers are designed and tested repeatedly to ensure that they will not be affected even when subjected to voltages of around 125V for long periods of time.

As Mr. Doubokujinman said, as a safety test for products rated 100V, we have confirmed that there is no problem from a safety standpoint even if a voltage change of ＋ -2 ～ 30% is applied to the product. However, the rated voltage in the U.S. is 120V, and it is necessary to consider that the voltage may vary by at least 20% above or below the rated voltage. Therefore, even if there is no problem for a short period of time, using a transformer with 120% of the rated voltage for a long period of time may increase the possibility of malfunctions. Therefore, I recommend the use of a transformer if possible. Hair dryers, futon dryers, etc., which generate a lot of heat, are especially dangerous because the heat generated is about 1 ． 5 times higher and the temperature becomes too high. I use a transformer with a capacity of 1500W for futon dryers and microwave ovens. However, most electronic equipment such as TVs and PCs are rated at 100 ～ 230V, so a transformer is not necessary. Since it is difficult to obtain a transformer with a large capacity in the U.S., I order one from Amazon.com in Japan. I am not familiar with the design of IH cookers （ and the latest electric kettles ）, so I cannot comment on what happens when a 100V product is used at 120V. However, IH heaters on the tabletop (1000W, 100V) seem to be working fine so far without a transformer. （ The time is so short ？ it's a risk when it will fail. ）

I use a transformer for my hair dryer
but not my 1000W induction heater （ lol ）
