iPhone 17 Pro’s 20-Minute 50% Charge Requires Apple’s New 40W Adapter

Apple’s $39 40W Dynamic Power Adapter is currently the only widely available charger that enables the new USB‑PD 3.2 SPR AVS fast‑charge profile.

Overview

  • Apple says iPhone 17 Pro and Pro Max can reach about 50% in roughly 20 minutes when paired with a 40W or higher USB‑C Power Delivery adapter.
  • The faster rate depends on the USB‑PD 3.2 SPR AVS profile, which negotiates more precise voltage for a quicker, battery‑safe ramp‑up.
  • At launch, Apple’s 40W Dynamic Power Adapter appears to be the only charger supporting that profile, and it is on sale for $39 in Apple Stores and on Amazon.
  • Current third‑party PD 3.0/3.1 chargers, such as Anker’s 45W Nano, will still fast‑charge but typically reach about 50% in around 30 minutes.
  • Pre‑orders are open now, with iPhone 17 models and the new adapter scheduled to reach customers on Friday, September 19, 2025.
