The power fast charger delivers more power for charging.
Power fast: 1.8 amps not sure of the voltage but guess about 5 volts.
The charger that came with my kindle: .85 amps at 4.9 volts.
Going by these figures, the power fast charger delivers about 1 amp more power.
Other adapters may be different, I used the specs from my kindle keyboard 3G.
