Philips Electric Toothbrush Sonicare Protect Clean Plus Plus Brush White (White Plus/White Compact/Tongue Included) HX6421/11

【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. ✅ [Sound wave technology function] The generation of sonic water flow (flow of saliva in the mouth) supports the gentle and effective removal of plaque and dirt.
