We used to have time to eat serial, but now everything has to catch the bus.
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
The point is that it is unclear which USB C can do what.
What’s the solution here though? I am 100% unwilling to go back to non-compatible and separate chargers for electronics where not completely necessary. It’s awesome taking only my laptop charger with me and being able to charge all devices optimally with it.
At least thunderbolt you usually get an icon plus number. Though most devices don’t label the ports.
All the other USB standards are confusing as shit.
there are too many standards.
for most part, rather than all that mess, maybe just stamp the cable/port with max wattage and max speed. So rather than worry about what standard am I using, I just know what I have and what goes where.
I think the complaint is more about the ports on computers, and the answer is for manufacturers to label the ports and for users to read them.
That last part is admittedly hard for a lot of people (myself includes at times).
The issue is, that’s not even enough! For example, the Dell 120 W laptop charger only supports 5V/1A or 20V/6A output, so phones will mostly charge at 5W because they dont support 20V input. Then there’s all the different charging protocols… Oh boy.
I’m not sure how your example is “not even enough”? If the charger is labeled as only having a 5v/1A and a 20V/6A profile, then where is the problem?
The problem is that the average consumer will have no idea what those numbers mean. If it was as simple as “this charger can output up to X watt”, labeling would probably be fine, but as soon as it gets more complicated than that, you’re beyond what most of the population is able and/or willing to deal with
Well, I’m all for universally easy things and a consumer not being stressed, but if we really got to the “I don’t get basic numbers” territory, then go learn some school physics, and maybe that Volts is the pressure in the pipe, Amps is how fast the water flows through it, and Watts is just pressure times flow rate - it’s that simple. Go and fucking learn what is what, there’s enough information in my comment alone.
