  "textContent": "The present disclosure provides a charging system, a power adapter and a charging method. The power adapter includes a first rectifier, a switch unit, a transformer, a second rectifier, a first current sampling circuit, a first capacitor bank and a second capacitor bank, and a control unit. The control unit is configured to output a control signal to the switch unit, and determine an output current of the power adapter according to a current sampling value sampled by the first current sampling circuit when the power adapter enters a first charging mode, wherein, the control unit is configured to isolate the first capacitor bank when the output current of the power adapter is at a rising edge or a falling edge, and enable the first capacitor bank to work when the output current of the power adapter is at a platform segment.",
