5V 1A vs 5V 1.7A or more...

I have a camera that uses an adapter (it came with the cam) that provides 5V 1A. I was given two power packs, one outputs 5V 1.7A and the other outputs 5V 1.5A. What can happen if I use either one of them rather than the plug-in wall adapter?

@Seizan,
The power packs list the maximum current the pack can supply while maintaining the listed voltage. If the camera uses less, you will be fine.

@Seizan,
Eng probably right. There's an outside chance however, unless specified as regulated, if one of the bigger units is used, given the smaller load its voltage might be slightly higher

@dalehileman,
Hi, thanks for the responses. But my concern isn't the voltage, it's the amperage... Both power packs output 5V which is what the camera uses. But the cam takes 1.0A, and both power supplies give 1.5A and 1.7A. What can the increased amerpage do to the camera?

@Seizan,
Nothing. The battery rating is the MAX it can supply. If the camera electronics are such that it demands 1.0 A, the battery will not supply more.

@engineer,
Thanks again folks. I really like this camera and didn't want it to go bad at a crucial time.
