Thanks. I tried to be very clear. My movie making skills don't match up to yours though.

[@warrenstamps6553]

Excellent explanation of how the charger communicates.

My apologies, very technical video for me (but thumbed up anyway). Question - 45w powerbank (Apple) with the replaced magsafe cord and connector (Aliexpress), identified as 85W on system report... Is there any problem for Macbook with such setup? All sudden battery capacity became lower than before.... I read that you can use higher W power bank without major problems (not vice versa), but still debating if I should replace cord on 2nd mac :) Thank you!

I see no problem with that setup. I am assuming you are using a MacBook Air. That computer will never draw 85W. Where did you buy the cable? Everytime I buy '85w' cables on Ali they send me 65w ones...
