【Voltage Compatibility】
Our products are selected to support international voltage ranges (e.g. 100–240V).
However, please make sure your local voltage is compatible before use, as incorrect voltage may still cause malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
