The flash charge port generally refers to the interface that supports fast charging, such as " QC" (Quick Charge) or " PD" (Power Delivery) and other standards, which can provide higher power output and achieve faster charging speeds. Flash charger is usually suitable for devices that support fast charging, such as some smartphones and tablets.

Fast charging port refers to the general conventional charging interface, such as USB-A interface or other ordinary charging interface.
