Can I use a 65W charger with an iPhone?

A compatible 65W USB-C charger can safely power an iPhone. The phone negotiates the power it supports rather than taking all 65 watts.

Short answer

Yes—when the charger and cable comply with USB-C Power Delivery, a 65W adapter is safe to use. The iPhone draws only the negotiated power it supports; the adapter's rating is its maximum output, not forced input.

Why

  • USB Power Delivery lets the charger and device agree on a supported voltage and current.
  • A higher adapter rating does not by itself make charging faster than the phone's own limit.
  • Cable quality, connector type, temperature and battery state affect charging behavior.

Important conditions

  • Use a USB-C to USB-C cable for iPhone 15 or later, or the correct USB-C to Lightning cable for older compatible models.
  • Avoid damaged, uncertified or suspiciously hot chargers and cables.
  • Wireless charging follows different limits and accessory requirements.

What to do

  1. Check that the adapter lists USB PD output profiles.
  2. Use an Apple or reputable standards-compliant cable.
  3. Disconnect equipment that smells, sparks, swells or becomes abnormally hot.
