Can I use my Philips shaver when it is connected to the mains?
Your Philips is designed to be used with foam or gel in the shower. Therefore, it does not work when it is connected to a power outlet,
Power outlets charge the integrated battery
The only thing the shaver does when it is connected to a power outlet is charge the integrated battery. It charges through an adapter that converts the voltage from the outlet to a safe low voltage. Nevertheless, we urge you to keep the shaver and the adapter away from water during charging. The adapter is not waterproof.
Some models are equipped with a unplug for use reminder. The unplug for use symbol will flash white to remind you that you have to unplug the shaver from the wall socket.
