I was experiencing tingling issue while charging MacBook Air M1. On checking it with tester I found its bulb was glowing. On checking it with multimeter I found the voltage to be around 100V. Including pics also. Are there anyone who is experiencing the same. The charger provided by MacBook Air has two pin no third earth pin is available.
MacBook Air 13″, macOS 11.3
You may very well have a ground fault issue on your mains
which can be causing such issues. I have run into this
in the past with various other types of equipment and
mains wiring in the building. I have even measured grounds
between outlets on one side of a room and another and
and found as high as a 120V differential between grounds.
This is especially possible in an apartment environment where
3 phase powering enters the building. While not intuitively
obvious, it can affect two wire AC connections.
I have done the same test as you have and have found no
issue.
Does not have to extension cord but something with Grounding Plug - but try
@woodmeister50 That crossed my mind and checked for ground fault and we already have ELR at our site. Thank you for your reply.
@p.phillip I don't think extension cable will solve that issue once I reach home I'll try it.
What is needed is this and can be purchased from Apple or Apple Store
