Comment on Realized 99% of all my chargers are USB-C. This can only mean one thing. New USB bout to drop!
deepus@lemmy.world 2 weeks agoI dont get how so many people complain about broken usb c connectors. Im not saying your wrong, just ive used the same 2 chargers for my phone for the last 5 years and same 1 for my laptop for 3 years, and yeah theyve gotten slightly looser but not to the point of breaking and being usable

The USB type C connector itself is amazing. I’ve never broken the physical connector, the problem is electrical only. The connector is capable of delivering a very high 240W of power, but the device/charger negotiate the power and voltage requirements to find the highest both can support.
But there are actually four parts of the system limiting the negotiated power:
The problem ultimately comes from the negotiation as many devices don’t use USB-PD (the theoretical “standard” for this) to save cost or allow different electrical configurations. This can lead to chargers incorrectly identifying devices as capable of accepting higher voltages than they can. Or devices can incorrectly identify themselves as capable of accepting higher voltage than they actually can.
If you’re using reputable decides from reputable companies using the included charger/cables, this will never be an issue. It’s only problematic when you want one charger for all your USB type C devices, as it now needs to support multiple communication protocols and voltage standards, hoping that no device identifies itself incorrectly.
