It won't fry your phone, the charging circuit will draw the power that it needs. What it WILL do is provide more than the 0.9A (at 5V) that a standard USB port can output (max) to allow for a faster charge. For comparison sake, the charger that came with the phone outputs 1A at 5V so you won't get a much faster charge.
