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.
2. Charger Brick Capabilities
USB-PD SourceFull 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 a safe 5 Volts. Higher voltages (9V, 15V, 20V, 28V) are only unlocked AFTER the phone or laptop explicitly requests them. You will never fry a phone with a 140W charger.
