MagSafe 3 cables work across MacBook Air and Pro.

Yes, they’re compatible. Apple standardized the MagSafe 3 connector starting with the 2021 MacBook Pro and the M2/M3 MacBook Air. Same plug, same port.

Now, a small caveat: power output depends on the charger, not the cable. If you plug a MacBook Pro’s MagSafe cable into a MacBook Air, it’ll charge just fine — the Air will only pull what it can handle. But the Air’s charger won’t top off a Pro as fast. That’s fine, just slower.

So go ahead and swap cables. It works, and it’s one less thing to keep track of.
