Power delivery:
- Most new iPhones are compatible with USB Power Delivery (PD).
- Apple’s official recommendation: use a 20W USB‑C adapter (but 30W is even better, especially for faster charging on newer models)

- For iPhone 16/16 Pro, some sources suggest support for up to 45W, though not officially confirmed by Apple .
Cable pairings:
- iPhone 15+ come boxed with a USB‑C to USB‑C braided cable
- Older models (12–14) use a USB‑C to Lightning cable.
Summary
To charge your iPhone (15 and up) quickly and safely:
- Use a USB‑C PD adapter — aim for 20W minimum, ideally 30W.
- Pair with the cable included (USB‑C to USB‑C) or Apple-certified alternatives.
- Choose reputable brands (Apple, Anker, Ugreen) for reliability and safety.
