As I see it, the operative question is: "is this particular Reader allowing current to reach the case when it's charging." ('cause if it's just a physical vibration, but no juice, then it's not a shock hazard
)
In order to find out if there is electric potential on the case, the steps I'd follow are pretty much what kacir suggested, specifically:
1) get/buy/borrow a multimeter (I've already got one, so that's easy
)
2) turn on the meter and set it to read DC voltage
3) plug the Reader into its wall charger, and the charger into the wall
4) place the negative lead from the meter in contact with a wall outlet's ground connection (make sure it's the
ground and not one of the other ones!
)
5) while holding the ground contact, touch the positive lead from the meter to the Reader's case (try several spots, just to be thorough)
If the meter's display shows a steady voltage at any point, then you know there's electricity leaking to the Reader's case. If it doesn't, then you can be pretty confident that there's not, and you're just dealing with a vibration (most likely a resonance vibration), so probably not anything to worry about.
