How is it possible to have low amperage input whilst higher amperage via USB output?

Question: How is it possible to have a low amperage power supply deliver a higher amperage output via USB?

Answer: As the iPower is 9V / 2.0A and the iUSB3.0 outputs 5v / 2.5A, the input current is stepped down thus enabling the output (amperage) to be higher.

In short, high to low voltage (input) = low to high amps (output).
