comment on USB type C chargers

My Charger supports 5 V / 9 V / 12 V / 15 V @ 3A and 20 V @ 5A fixed profiles and 3.3 V - 21 V @ 5 A augmented profile. Be careful many chargers marked with 100W (even Ugreen) will only support 65 W PPS (3.25 A) with limited voltage range. They may not supprot voltages below 3.3 V. Some will even have two PPS profiles with differnet voltage / current ratings.
