The difference between power adapter and fast PD charger
Different ingredients
1. Power adapter: It is a kind of electronic appliances for small portable electronic equipment and power conversion equipment. It is composed of shell, transformer, inductor, capacitor, control chip, printed circuit board, etc.
2. Fast-charging charger: It consists of a stable power supply (mainly a stable power supply, a stable working voltage and sufficient current) plus necessary constant current, voltage limiting, and time limiting control circuits.
Different current modes
1. Power adapter: from AC input to DC output, indicating power, input and output voltage, current and other indicators.
2. Fast charging charger: adopts constant current and voltage limiting charging system. Generally, the charging current is about C2, that is, a 2-hour charging rate is used. For example, the charging rate of 250 mAh for a 500mah battery is approximately 4 hours.
Different usage scenarios
1. Power adapter: specially designed for the normal operation of the equipment; its output current must match the current required for the normal operation of the equipment, and it must be able to work stably for a long time.
2. Fast-charge charger: The output power of the fast-charge charger is designed to meet the needs of battery charging, and does not consider directly providing the required current value for the operation of the device; therefore, the output current of the charger may not meet the normal operation requirements of the device.
