Thank you so much... I am worried a little about battery life... I don't know if charging with 140w cause heat or something that harms my MacBook. It is in the supported list now, though.

Stop worrying about the battery, The MacOS manages the battery very well. You can leave the computer plugged in all the time and neither the battery nor the computer will be damaged. Let the MacOS do its job.
