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?

Having experience with electromechanics - I have seen times where this was done on purpose to make sure that people aren’t trying to reuse an incompatible plug for charging purposes. NiCd doesn’t charge the same as LiFePo, Li-ion, etc. Charging voltages, polarities, stability of power output, etc.

I bought this one from Conair because it is rechargeable with USB-C.

And how is it as a device?

My next shaver will be USB-C. It’s now a standard for charging whatever you want.

I know a lot of RC brands did this too. They didn’t want people blowing up their Li-On batteries with old chargers, or getting complaints because it takes three days to charge.

Careful what you wish for. Putting advanced electronics into very simple devices will just make them fail a lot faster.
Some old device just needed 12V over a barrel jack to run some motor or light and charge the battery and it lasted a decade - only failed because the battery got old. New one now needs a state of the art power delivery chip to negotiate the right voltage and current, and all over a very fine pitch connector that will fail if you look at it wrong. Not looking good on the durability front at all.

Are you Apple engieneer? Because I have no idea why PD chip is state of art for you

Since when is a BMS advanced technology?

The only issue I have with USB power solutions is that it’s also capable of data transfer, which is bad. Imagine a dystopian future of being tracked by companies and governments by the places you plugged your shaver in at, of all the stupid things.

It’s capable of data transfer…but to a power brick in the wall?
uis@lemm.ee 7 months ago
Making communication over barrel jack is not hard either.
echodot@feddit.uk 7 months ago
USB is capable of data transfer but only if there’s compatible hardware in the device. The shave it doesn’t have any capacity to transmit data so what’s it going to do there’s nothing to track all they get is “someone has plugged something that requires some power into this port, but I don’t know what cuz it doesn’t have any brains”

We should all use public chargers. I heard they’re safe
qaz@lemmy.world 7 months ago
I think the bluetooth/wifi functionality on most modern electronics is much more worrisome than that.
Aux@lemmy.world 7 months ago
No, shavers should not use USB C. Because in developed countries you cannot have USB in the bathroom. We have special shaver sockets and they’re not USB compatible.

Then you should refine your laws. Because my shavers all use USB C; and the EU has mandated USBC in specific products, and it wouldn’t be a bad idea to expand that.
