Palm Zire 72s / Palm 22 Question Is the 500 mA charger from the Palm 22, which I...

...HAVE adequate for a 72s? I know the listed power requirement of the Palm One Zire 72s is 1 A versus the 500 mA of the Z22, But will this rig charge the larger machine or is there some incompatibility issue other than this?

Both devices SEEM to have the type of plug, but the dedicated power plug on the 72s is NOT this plug. So, will the charger work? Or is the charger plug on the z22 going to FRY the Zire 72s if it gets plugged into it by mistake some fine night? Cause I know myself well enough to know I'm going to do that if I keep both systems, and one is an accident waiting to happen.
