Regarding this, what kind of charger does a MacBook Pro use?
For instance, the MacBook Pro 13 inch uses a 60W MagSafe, but you can use an 85W MagSafe to charge or power it (although it will not charge any faster).
Also, can I use any USB C charger for my MacBook Pro? For best performance, use an 87W power brick with a 5A/100W USB C cable. Or buy an Apple MacBook Pro USB C power brick, since those are its specifications. More watts will not result in faster charging, unless the MacBook Pro can negotiate a higher current draw.
