Edit: see comments for clarifications.
I am probably late on this one, but god damn this is one nasty trick by Philips.
Context; I recently decided to upgrade my shaver, from a Philips One Blade to Philips an all-in-one-trimmer-7000. As you can see on the pictures below, they changed the charger for the adapter by maybe 1–2 millimetres, just so the old charger could not be used by the old charger. Now, this normally isn’t a big deal, but with the new trimmer, the charger is USB-A only. Where’s the previous one had the plug on it instead. To me this is mildly infuriating as I know need to get an extra adapter just to charge my shaver in the bathroom. They had the exact same design for the chargers, yet changed it just slightly so they wouldn’t be able to be reused? Why… Philips… why?
Edit: many good points in the comments! I don’t know how to manually check the voltage, but seems like folks figured it out in the comments too. Should have just been USB-C!
Nice of then to make sure you cant accidentally blow up your new razor because you assumed the old cable would work if it fit.
So stupid idea. What if some 220V cable from a third-party manufacturer does fit?
Plugging in a random cable from some random manufacturer is not a thing that most people would consider doing. (Furthermore, I doubt that any 220V cable would fit, these connectors on the picture are smaller than they look).
I have about ten of these cables, and they are interchangeable.
