When a headset is connected, Extender will supply power via the USB connector to ensure that the battery in the headset is not depleted. In order to save power, Extender will turn off power to the headset USB connector as described by the following table. It is possible to charge a headset and Extender at the same time if they are daisy chained together, however it will be quicker to charge the headset connected directly due to limited current on a USB port.
