Does the Samsung 45W Power Adapter Fast-Charge the Apple iPhone 14 Pro Max?
Yes, but only in fallback mode — 27W via USB PD, not the device's fastest proprietary protocol.
The Samsung 45W Power Adapter doesn't speak the Apple iPhone 14 Pro Max's fastest protocol (USB PD, up to 27W) — instead they fall back to the universal USB PD, negotiating 27W. That's still real fast charging, just not the device's absolute ceiling.

How your cable affects this
The wattage above assumes an adequately rated cable. Here's what actually happens with three common cable situations:
| Cable | Real wattage | Cable-limited? |
|---|---|---|
| Standard 60W-rated cable (3A, not e-marked) | 27W | Not the bottleneck |
| 100W / 5A e-marked cable | 27W | Not the bottleneck |
| Unrated / unknown cable (assume worst case) | 27W | Cable-limited |
