Just curious, does the MBP M1 know the difference between charging and being charged? with the additional USB C ports I was wondering if I plugged in a powerbank while having the MBP plugged into to charge already would it start charging the powerbank? similarly to just plugging in an iPhone cord. and if yes, at what wattage does the USBC MBP port charge at? or would it try to charge the MBP in addition to the outlet charging? I understand the 14" has the ability to charge at 90w, if I'm using anker 65w and have a portable anker 65w will it try to combine the two and pull 90ws?
