Abstract

A system may have a power adapter with multiple ports for supplying power to electronic devices. The electronic devices may include devices such as cellular telephones, wristwatch devices, laptop computers, and tablet computers. The power adapter may supply power using wired links and wireless links. An online user account that is maintained on computing equipment in the system can communicate with the electronic devices or power adapter over a communications network. The power adapter and other components of the system may gather information such as user device charging priority settings, battery charge state information, device type information, usage history information, calendar information, and other information. This gathered information may be used in identifying an optimum power transfer strategy for the power adapter to use in transmitting different amounts of power to each of the electronic devices.

Claims21

Dependent claims

A power adapter configured to supply power from a power source to electronic devices, comprising:

power transfer circuitry that is configured to supply power to a plurality of electronic devices over respective power transfer links;
communications circuitry that is configured to receive information from the plurality of electronic devices including device usage history information;
and
control circuitry that is configured to direct the power transfer circuitry to transfer power to at least one of the electronic devices over at least one of the respective power transfer links in an amount that is based at least partly on the device usage history information.

1 more element

Apparatus that is configured to provide power to a plurality of electronic devices each of which has a battery and each of which has communications circuitry that is configured to transmit battery charge state information for the battery and device type identification information, comprising:

circuitry that is configured to receive power from a power source;
and
circuitry that is configured to receive the transmitted battery charge state information and device type identification information from the plurality of electronic devices, wherein the circuitry is configured to supply each of a plurality of electronic devices with the power in respective amounts that are based at least partly on the battery charge state information and device type identification information.
