Abstract: Circuits, methods, and apparatus where a dongle or adapter may provide continuous power in the event of a disconnection of a charging device. One example may provide a dongle having a charge storage circuit. A charging device connected to the dongle may be used to power an accessory also connected to the dongle. Following a disconnection of the charging device, the dongle may use the charger storage circuit to provide power to the accessory for a first duration. After the first duration, a host device also connected to the dongle may provide power to the accessory via the dongle.
