Most of the charging heads used in handheld devices such as mobile phones or tablets (such as 5V1A or 5V2A) are an ordinary USB power adapter, and the output is only a USB interface (mainly a regulated power supply, providing a stable working voltage and sufficient current) plus necessary It is composed of control circuits such as over-current, voltage-limiting, short-circuit protection, etc., which play the function of providing voltage and current. When the battery is actually charged, it is adjusted by the control circuit on the device. Therefore, we also call it "USB power adapter".


    In fact, there is a difference between a real charger and an adapter. A charger usually refers to a device that converts alternating current into low-voltage direct current. It contains control circuits that meet the charging characteristics such as constant current, constant voltage, and trickle. It generally charges the battery directly without passing through any intermediary equipment and devices. The charger process is: constant current-constant voltage-trickle, three-stage smart charging. The three-stage charging theory in the charging process can greatly improve the charging efficiency of the battery, shorten the charging time, and effectively extend the battery life. Three-stage charging uses constant current charging first, then constant voltage charging, and finally floating charging for maintenance charging.


    From the circuit point of view, the power adapter only provides voltage and current functions to meet the drive of the device and play a power supply role, and cannot directly charge the battery. The charger circuit has more battery charging management, which can directly charge the battery.
