An electronic system may include a charging device and an electronic device. The charging device may include an input port, a charge circuit, a storage, and a connector device. The charging device may receive a direct current (DC) voltage at the input port. The charge circuit may receive the DC voltage and provide a charged voltage to the storage. The electronic device may include a body, a battery, a first pad directly on the battery and a second pad directly on the battery. The battery may receive the DC charged voltage when the electronic device is coupled to the charging device.

The present disclosure provides a power adapter and a terminal. The power adapter is coupled to a mobile terminal via a USB interface, and a data line of the USB interface is used for a bidirectional communication between the power adapter and the mobile terminal. The power adapter supports a normal charging mode and a quick charging mode, and a charging current of the quick charging mode is greater than a charging current of the normal charging mode. The method includes: communicating, by the power adapter, with the mobile terminal via the data line of the USB interface, so as to determine to charge the mobile terminal in the quick charging mode; and adjusting, by the power adapter, a charging current of the power adapter to be the charging current of the quick charging mode to charge the mobile terminal.

A system for powering a network element of a fiber optic wide area network is disclosed. When communication data is transferred between a central office (CO) and a subscriber terminal using a network element to convert optical to electrical (O-E) and electrical to optical (E-O) signals between a fiber from the central office and twisted wire pair, coaxial cable or Ethernet cable transmission lines from the subscriber terminal, techniques related to local powering of a network element or drop site by the subscriber terminal or subscriber premise remote powering device are provided. Certain advantages and/or benefits are achieved using the present invention, such as freedom from any requirement for additional meter installations or meter connection charges and does not require a separate power network.

Methods and systems for providing intelligent power distribution. A distribution point unit is connected to a plurality of user units in a telecommunications system. A loss of power to the distribution point unit is detected. It is determined that at least one user unit has backup power. Based on a determination that at least one user unit has backup power, a power mode for the distribution point unit is selected. The power mode is implemented on the distribution point unit.
