The minimum wattage to effectively charge an M2 MacBook Pro really depends on the screen size and model. For the 14-inch M2 MacBook Pro, Apple includes a 67W adapter by default (or 96W with the M2 Pro chip). So while technically you can charge with less, those higher wattages are what ensure full-speed charging and can maintain or increase battery level under load.
If you use a 30W adapter, like the one that ships with the MacBook Air, it will charge your MacBook Pro, but it’ll be very slow — and in some scenarios (like if you're doing heavy work or running external displays), it may not keep up at all. The battery could actually still drain slowly during use. It’s perfectly safe, though; USB-C Power Delivery ensures that the Mac only pulls what the adapter can handle. So the worst case is slow or no charging during intensive use, but no harm done.
If you're stuck with just 30W temporarily, it's fine for overnight or idle charging. But for regular use, especially if you work the machine hard, I’d recommend at least a 60W+ adapter, preferably closer to what Apple ships with the model.
