Can I charge my AirPods with MacBook charger?

It depends on what model of AirPods you have. If they are gen 1-3 they are lighting. If they are pro 1 and some pro 2 they are lighting. If they are recent pro 2s or the recent max the yes, usb c max charger would work. A MagSafe Mac charger would not do anything.
