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.
