Charging power requirement: 5V, 1A

The Apple mini USB power adapter for all iPhone/iPod models has a power output of 5V and 1A. This seems like an obvious answer that you have to follow the specs. But to others who have kinda researched about rechargeable batteries, a smart charger can supply a lower amperage to safely trickle charge a battery versus higher amps that would provide a quick charge.

Since the iPhone 3G/3GS does not specify the exact power requirement it requires, my question and concern is that each USB outlet of various computers does not give a standard 1A output rating the way the Apple mini USB power adapter provides. For example Belkin provides a mini surge protector with a USB outlet that gives 5V and 500mA.

Can we be slowly damaging the iPhone's batteries by feeding it different USB power outputs?
