M2/M3 MacBook Air vs M1 MacBook Air: M2/M3 fast charge with 67W adapter, M1 doesn't support it

Only the M2 and M3 MacBook Air models support fast charging — the M1 is stuck at regular speeds. Use Apple’s 67W or 70W adapter with MagSafe 3 to hit 0–50% in 30 minutes. USB-C works too with a Power Delivery cable, but MagSafe is more convenient and saves the port. The 30W or 35W adapters won’t fast charge.
