All devices now have chips that do a handshake with the charger, exchanging information about supported standards and charging using the best common option. So I charge my prohe with a 90W laptop charger, even when it is unable to use the whole wattage
On the other hand, I have a USB-C charged laptop, but it only accepts one specific spec of 45w, and one specific spec for 60w. This means that 90% of usb-c chargers don’t work for it, including chargers that support 45w or 60w charging. This means that even if you buy a charger with the right wattage, its effectively random whether it will work or not.
You just note down the company who delivered the idiotic product: next time your options for purchase are narrower, but it narrow the chance to buy products badly designed.
Just because some companies sells USB butplugs it doesn’t mean USB standard is necessarily a pain in the ass overall.
I have a fucking thinkpad that does not follow the USB PD spec!
The thing has only type-c ports, the thing is relatively recent (2023), the thing accepts 140W via type-c, I never bothered to check the actual specs and assumed PD 3.1
Turned out that no, this is not PD, this works only via proprietary power brick that outputs 20v@6.75A, that I didn’t get as I already have a bajilion of PD 3.0/3.1 power supplies at home.
