| Evaluation Vector | MagSafe 3 | USB-C (Power Delivery) |
|---|---|---|
| Accidental Snag Response | Safe Breakaway (Zero drag) | High Pull Risk (Chassis falls) |
| Port Preservation | Leaves 3 TB Ports Free | Consumes 1 Thunderbolt Port |
| Cross-Device Compatibility | Proprietary to MacBook | Universal (iPad, Phone, SteamDeck) |
| Display + Power (1 Cable) | Power Only (No data stream) | Supported (Single-cable hub) |
| Max Standard Fast Charge | Full 140W EPR supported | Up to 100W (or 140W with EPR) |
Strategic Synthesis:
- MagSafe provides near-instant magnetic coupling and preserves full Thunderbolt peripheral bandwidth.
- USB-C remains ideal when connecting to external USB-C / Thunderbolt displays that deliver upstream PD.
- Carry a USB-C to USB-C cable for road travel to share chargers across all gadgets without dedicated cables.
