Using a higher-watt adapter is safe; your Mac draws only what it needs. Lower-watt adapters may charge slowly or not fast-charge.
| Mac Model | Recommended for Fast-Charge | Also Works (slower or standard charge) | Notes |
|---|---|---|---|
| MacBook Pro 16-inch (2021 or later) | 140W (A2452) via MagSafe 3 | 96W / 70W / 67W | Fast-charge requires 140W + MagSafe 3 cable. USB-C cable also supported (no MagSafe). |
| MacBook Pro 14-inch (2021 or later) | 96W (fast-charge) or 140W | 70W / 67W (standard/slower) | Some 14-inch configs ship with 67W; 96W enables fast-charge. 140W is OK; device limits draw. |
