    As of USB-PD 3.1 there are now nine fixed voltages - 5, 9, 12, 15, 20, 28, 36, and 48V - and two variable-voltage modes; PPS with 3.3 - 21V in 0.02V increments, and AVS with 15 - 48V in 0.1V increments.

    Combined with a few different current limits, some of these features being optional, and then doubling down with what your cable does or doesn’t support, amazing anything gets charged at all.
