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!
My Philips shaver does not work whilst charging. What’s that all about?
Luckily the battery is good but it gives very little warning when its about to run out. I dont grow facial hair very quickly or very thickly but several times I’ve had to leave the house partially shaved. Doesn’t make any sense. That’s the whole point of electricity, to use stuff whilst plugged in!
Wet/dry shavers can’t be used while charging because some moron will use it in the shower while plugged in. That’s what the instruction booklet essentially said for my oneblade
Yeah that’s a regulatory requirement in some regions
Ah fair enough. This never occurred to me as we dont have a power socket in the bathroom. Also I’m a typical man so didn’t bother to read the instruction manual.
Some of the older models work while charging. For example the MG7790 or MG7750/49 (not to be confused with the new version 7910/49).
The reason I know this is because I recently bought one from amazon specifically because I want it to work while plugged in but they sent me one that doesn’t (MG7770). I sent it back and now waiting for the correct one to be delivered.
