Can anyone explain why i get sharp electrical shocks when i touch the bottom edges with my wrists? Or its just me?

Not just you. If you use the Apple extension cord with the 3 prong outlet plug, this doesn’t happen.

MacBooks (and many laptops) have a tiny amount of alternating current that leaks through the metal chassis to ground. When you use the compact 2-prong power adapter (the “duck head” without a ground pin), there’s no path for this leakage current to safely flow to earth ground — so it flows through you instead, creating that tingling sensation.

Interestingly I haven’t felt this when using my 2 prong NAND Anker adapter.
