Question: How do I do a Time Machine backup on my external hard drive before my computer battery dies?

Re-enforcing Kappy’s suggestion, there are multi-port USB-C docks that include a pass-through USB-C power port.


Apple sells them, and many 3rd parties sell them


Just make sure it is compatible with your make and model MacBook.
