This document discusses, among other things, a charging emulator configured to be coupled to an electrical interface, the charging emulator including a control circuit configured to receive information about a peripheral device coupled to the electrical interface and a charger circuit configured to provide power to the electrical interface using the received peripheral device information. In an example, the charging emulator can include a component of a host device including a low-power state, and the charger circuit can be configured to provide power to the electrical interface when the host device is in the low-power state. |
