Slight tingling sensation on iPad back when plugged into wall electrical pt?

When i plug in my iPad (local set) into the wall outlet to charge there will be a slight tingling sensation felt on the aluminum skin of the iPad.

Do you guys who own one encounter this before? It only can be felt using the wall charger, on USB trickle charge can't feel anything.

I had this before on my old iPod mini and I've seen similar posts in the Apple discussion forums, but so far no one has found a good explanation on this effect.

It seems to be due to the 10W charger. Plug it to iPhone 4 oso same...

The sensation might have been due to that experienced on the MacBook Pros. Should be fine unless you are paranoid over it.

When you plug in to your computer and it says NOT CHARGING, actually there's a slight charge going on, just that it takes a long time before you realise it.

I'm not sure if its not a problem. I found a thread over in the Apple Discussion forums:

http://discussions.apple.com/thread....art=0&tstart=0

Seems that the iPad 3 pin charger is a dummy 3 Pin (i.e. its not really linked to ground), that's why you can feel the tingling sensation on the set.

Will give Apple a call about this, in the meantime, if anyone can test out on the iPad with a multimeter and read the AC on the device when its connected to the charger, that would be good to share to really see if this is a real problem or not.

I think so.

I think it's because there is no real ground. The ground pin is not connected to anything. That's why the same adaptor base is also used with the euro 2-pin plug

Well I guess that's called a floating ground.
