Can I use my Philips Sonicare charger with other toothbrushes?
The DiamondClean and DiamondClean Smart chargers are not interchangeable with each other or with other Philips Sonicare toothbrush handles. Even if the charging light on the handle blinks, it will not charge properly. We advise to always use the charger that comes with your Philips Sonicare DiamondClean and DiamondClean Smart toothbrush. Chargers can look similar. To verify that you are using the correct charger, see the table below. Each handle is only compatible with the charger base below the handle code ID.
