1. A method for controlling power delivery to an electronic device having proprietary and default power modes for power delivery, the method comprising the steps of:
connecting a power delivery adapter to the electronic device, wherein the electronic device is a portable loudspeaker having an amplifier and a rechargeable battery;
completing a power delivery protocol between the power delivery adapter and the electronic device;
delivering power to the electronic device according to the default power mode, wherein when power is delivered to the portable loudspeaker according to the default power mode, the amplifier only draws power from the battery;
requesting a proprietary protocol for the proprietary power mode from the electronic device;
when no proprietary protocol is communicated to the power delivery adapter, the power delivery adapter continues to deliver power to the electronic device according to the default power mode;
when the proprietary protocol is communicated to the power delivery adapter, the power delivery adapter makes a request to deliver the power to the electronic according to the proprietary power mode;
confirming the request to deliver power according to the proprietary power mode; and
delivering power to the electronic device according to the proprietary power mode, wherein when power is delivered to the portable loudspeaker according to the proprietary power mode, an amplifier in the portable loudspeaker draws power from the power delivery adapter.
