you always have to manage a million different cables for each one, and they all suck. why can’t we just use AAA batteries instead of these shitty lithium ones? it’s so fucking frustrating. where can I find gadgets that work while plugged in, or at least don’t need to be recharged every two fucking days?
No one is using DisplayPort with an electric toothbrush. You’re confusing the issues solved by the EU legislation.
Even looking at power delivery alone, there’s still different voltages and wattage, as well as cable specs. Nothing really changes. You still end up having different cables for different devices, essentially.
I haven’t run into a USB-PD charger that doesn’t fall back to 5V/2A if it can’t negotiate power delivery. As long as you buy a 45/65/100W PD brick and a supporting cable (both are cheap and getting cheaper) you don’t really have to worry about what you might be charging.
Even 20-25W phone chargers and cables will generally slow-charge most laptops in a pinch.
Charging my laptop with my powerbank I have for my phone is a moment of glory.
