Why do USB-C to USB-C chargers charge quicker than USB-C to USB?
In: Technology
Standard USB-A (the regular computer USB ports) only supports 5V, which is fine for charging a phone at maybe at most 10W, not much more than that, because it would require too much current through the thin wires
USB C on the other hand supports usb power delivery, when means devices can ask how much voltage they want and the charger (if supported) will give it to them, so it can deliver more power
I should also add that there are some quick chargers on USB A, but it’s not a USB protocol standard, it uses other protocols like quickcharge to deliver the right voltage to devices tagt support it
