--------------------------------------------------- 【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.

【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 appropriate voltage or equipment. --------------------------------------------------- 1.
