USB-C PD & Fast Charging Checker
USB-C is not just one speed. The charger and device digitally negotiate voltage profiles (5V, 9V, 15V, 20V, 28V EPR) and PPS protocols over CC communication lines.
Charger Brick Capabilities
Full Speed Charging Confirmed
The charger provides sufficient voltage profiles and wattage. The device will safely negotiate max charging speed over the USB-PD handshake.
USB-C chargers always start at standard 5 Volts (vSafe5V). Higher voltage profiles (9V, 15V, 20V, 28V) are only activated after the device negotiates power data objects (PDOs) over the Configuration Channel (CC) line. A high-wattage charger will safely deliver only what the connected device negotiates.
