The devices talk to each other basically. This is why it doesn''t charge from ordinary "dumb" chargers, though I don''t know if that applies to your MacBook charger.
What are power amplifiers?
In general a power amplifier is designated as the last amplifier in a transmission chain (the output stage) and is the amplifier stage that typically requires most attention to power efficiency. So a power amplifier supplies power to drive the final load, while other amplifiers are more likely to drive higher-impedance inputs.
