The difference between Apple's 20w original fast charge and pd fast charge is the charging protocol and power output. First of all, the Apple 20w original Fast Charge is a charger developed by Apple Inc., using Apple's proprietary charging protocol. This means it is more compatible with Apple devices, providing a more stable and efficient charging experience. The pd fast charge is a universal fast charge protocol, which can be applied to a variety of brands of equipment.
pd Fast charger can dynamically adjust the output voltage and current according to the needs of the device to achieve faster charging speed.
In addition, the power output of the Apple 20w original fast charge is 20w, while the power output of the pd fast charge can change according to the needs of the device, and usually can achieve higher power output. To sum up, the difference between Apple's 20w original fast charge and pd fast charge is the charging protocol and power output.
Apple 20w original fast charge is more suitable for Apple devices, providing a stable and efficient charging experience; pd fast charge is a universal fast charge protocol, suitable for a variety of brands of equipment, and can provide higher power output according to equipment needs.
PD is Apple's proprietary fast charge protocol, 20 watts, pd fast charge head is suitable for charging Apple mobile phones and ipads fast charge head. The ordinary 20-watt fast charger may be the QC agreement, that is, the agreement for charging Qualcomm's mobile phone, and the agreement for charging Android mobile phones. Although the two models are similar in power, the different protocols may lead to different charging speeds, so it is still necessary to match the fast charging.
