【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Note:
1.In order for the converter to work normally within the input voltage range, the input voltage must not be lower than the minimum or maximum input value limited by the product during use, and the input voltage value must be higher than the output voltage value. At 2V or more. If there is no voltage difference of 2V, the output value will be lower, but there will be no damage (affect) to the use of the converter.
2. The input current must be greater than or equal to the power required by the output load device (for example, if the load device power requires 100W, the input power must be greater than or equal to 100W). When using a converter, the current of the load device should not exceed the maximum current value that the converter can withstand, leaving as much margin as possible in the converter so that it can work properly and achieve the best conversion.
3. The positive and negative poles of the converter cannot be reversely connected during use. Reverse connection may damage the converter. It is recommended to add appropriate fuses to the input terminals during use.
4.The chip operates in light load mode when no load, and the output voltage may fluctuate within a certain range.
