1. A power converter, comprising:
- a first circuit having an input configured to receive a power source having a first voltage, and configured to convert the first voltage to a second voltage provided to an output, the first circuit configured to power a portable electronic device; and
a second circuit coupled to a receiver and to the first circuit and configured to identify if the power source is an aircraft power source by detecting noise of the power source by the receiver.

Abstract
A power converter having an aircraft power source detector configured to limit the amount of power that can be drawn by the power converter when utilized in an aircraft. The power converter may detect an artifact of the aircraft power source, such as the 400 Hz ripple noise on an aircraft power line, or existing in the aircraft cabin, such EMI or aircraft lighting.
