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!
The electrical code in my area requires using GFCI outlet for outlets within a certain distance of water source. I don’t remember precisely the distance (and it likely vary a bit by jurisdiciton), but i know that in my bathroom, there’s nowhere beyond it.
In order to use that sort of outlet in a bathroom like mine, it would have to have GFCI protection as well as USB, be a second outlet wired to the GFCI protected terminal of a GFCI outlet, or be wired to a circuit breaker with GFCI protection built in, in the electrical panel.
In all my cases where I installed those, I got lucky and the GFCI protection is upstream in another outlet somewhere.
