I have lost the power/charger cable for my Philishave QT4020. Can you supply?

There are plenty available online but beware of the very cheap Chinese models that mostly will function ok, at least for a while, but they often have interference suppression components missed out and can cause EMI (electromagnetic interference) to nearby radio and tv.
It is also not a good idea to leave them unattended...
