Abstract
A power adapter with a power saving mode includes a power adaptation unit. The power adaptation unit includes a pulse width modulation control unit and a power saving signal receiver. The power saving signal receiver is electrically connected to the pulse width modulation control unit. When the power adapter enters a working status, the power adapter charges a battery. After the power saving signal receiver receives a battery fully-charged signal, the power adapter enters a sleeping status.
