Driving the compressor via a belt will be more efficient than driving a generator/alternator to produce electricity to drive a motor to drive the compressor. No conversion of energy is perfect - usually far from it.

But, yeah, it takes about 167A at 12V to produce 2kW.
P = I * E = 166.6A * 12V = 2kW
