Good to know

iPhone 15 and later (including iPhone 16e, 17e and iPhone Air) use USB-C; Lightning cables, docks and Lightning-plug accessories do not fit them without an adapter.
Fast-charge speed depends on charger wattage and protocol (USB PD; Google Pixel fast charging uses USB PD PPS).
iPhone 18 Pro / Pro Max only reach their fastest wired speed with a 60W-capable adapter that supports USB PD Adjustable Voltage Supply (AVS), per Apple.
Samsung 45W charging (S23+/S23 Ultra) is quoted by Samsung with a 5A USB-C cable; a standard 3A cable limits it.
Qi2 and MagSafe chargers also charge Qi-only phones, but at reduced (baseline Qi) speed and without guaranteed magnetic hold on phones lacking magnets.
Apple: non-MagSafe Qi-compatible devices charge at reduced speeds on the MagSafe Charger.
