iPad gives tingly light vibration electrocution when plugged into mains

I thought I'd ask whether this was normal seeing that my friends ipads are doing the same thing;

Using the supplied AC adaptor and supplied USB cable, when I plug my iPad into the mains its gives a kind of tingly vibration feeling on the back, especially when I move my hand around the surface. When not plugged into the mains or when plugged into my PC it does not happen... suggestions? Is this a fault?

Ipad Wifi 32GB, Windows 7

I get exactly the same thing. I just received the iPad, plugged it into the mains charger (UK) to fully charge it for the first time, and felt the same thing. I wasn't sure if it felt like an electric charge or a vibration in a similar way that the iPhone. It only happened when I placed it down on a level surface. It didn't seem happen when held up above, say, a 20 degree angle from the desktop, but occurred again when placed back down.

Interestingly, in the time it took to find this topic, it seems to have stopped doing this or seems less noticable. Maybe it has charged me up!

  • Your power supply is not earthed with the short lead: it makes my Power Book Pro case tingle (not the track-pad). It is due to a floating earth! I got around this by using the longer mains charger lead, which is earthed, plugged permanently in the Power Book Pro via a mains timer, so that the charger is not charging the battery all the time, but the computer is earthed.

I see a lot of people talking like it won't kill you ect... Who's to say what these voltages can do to anyone's CNS over any period of time. Sometimes things can make you feel as if you wish you were dead.


At the moment I'm battling with Asymmetrical hearing loss accompanied with loss of balance. If I recall correctly the last time this happened. I had used my ipad 2 consistently for the better part of the day without my Otterbox. I wasn't using headphones. Am I sure this is what caused it! Nope Not saying it did.


Just throwing this out there to see if I'm the only one or maybe there is someone else out there that does understand and is able to test the possibility. It would seem to me that our sense of touch would be harder to trigger a signal from than the intricate switches of our central nervous system. I'm no Biologist.
