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 battery died on my old shaver. Because I can’t leave well enough alone, I decided to see if I could replace it. Spent so much time tracking down the battery model number and looking for a replacement only to find out it’s a standard triple a. It’s identity was obfuscated by the stupid labeling. Soldered it in and bam, razor still works for several years.
ive got philips body groomer which in time become somehow a curiosity: once its fully charged it runs until battery gets dry as it should but if i by any chance press the button i need to the whole cycle charge
