Macbook leaking eletricity

I have used quite a few Macbook pro since 2015, 13", 15", and all these are bought locally that comes with 3-pin plug, be it in the office, or at home, a lot of times with the charger plugged in, my palms will have this tingling numbness like getting electrical shock. I have to unplug the macbook till like power is low, then plug back in to charge, when it hits 100% and continue to charge, the shocks will be back!

Seems like no matter what kind of model I use, will all have this problem, the adapter is just a 2 pin adapter, although the plug is 3 pin, it is no use since nothing will get connects to the earth pin, I see youtubers suggesting for 2pin plug to change to 3pin plug, I think that is total waste of money!

I m in Singapore, here, all the macbook comes with 3 pin plug, yet all leak electricity, too bad my company only issues macbook for work, so just unplug and plug till the charger breaks, then change another electricity leaking macbook.
