If you want to change your electric toothbrush from wireless to wired charging, you will need to find the charging port of the electric toothbrush and plug the charging port into a suitable charger.
You can choose to buy a wired charger for an electric toothbrush or use a universal charger for an electric toothbrush, but you need to make sure that the charger you choose can provide the correct voltage and current to charge an electric toothbrush. It should be noted that wired charging may destroy the waterproof performance of electric toothbrushes, so special care needs to be taken when using wired charging.
To change the electric toothbrush from wireless charging to wired charging, you need to open the case of the toothbrush and find the charging circuit board. Remove the wireless charging board, then connect the wired charging board, connect the electrical route, and then seal the shell. It should be noted that the modification process requires a certain amount of electronic skills and safety awareness, and should be careful when operating to avoid circuit short circuits or other safety hazards.
Toothbrush wireless charging using a wire connection can be changed to wired charging.
