Can You Charge a MacBook With Both Ports?
Although MacBooks can have chargers plugged into more than one port, the system will still only use one charger. The MacBook will use the power from a charger with the highest wattage, rather than using both of them.
It makes sense that Mac would charge quicker with two chargers, but this is incorrect, the MacBook will charge with the highest wattage.
For example, if you have a 100W charger like this one from Amazon connected to your MacBook, your MacBook will charge from that charger rather than this 75W charger, regardless of which charger you connected first.
The newest MacBook Pro can be fast-charged with a 140W USB-C Power Adapter + USB-C to MagSafe 3 Cable, it’s better to leave one of your USB C ports open for accessories like an external SSD, take a look at some of your best options on Amazon here.
