The fastest charging figure Apple publishes for the iPhone 18 Pro, up to 50 percent in around 15 minutes, requires a 60W USB-C adapter that Apple sells separately and never names on the phone’s pages. The adapter that fits the description is called the 40W Dynamic Power Adapter with 60W Max, and the footnote on its own store page says it was used for iPhone Duo battery testing in July 2026.
So the hardware behind the headline charging claim carries two wattages in its name and a test reference to a different phone, one that does not go on sale until October 23. Apple has published no price for it in any of the ten storefronts we checked.
Key facts: the 15-minute claim and what it needs
| Item | What Apple publishes |
|---|---|
| iPhone 18 Pro and Pro Max wired claim | Up to 50 percent in around 15 minutes with a 60W USB-C adapter, sold separately |
| Adapter named on the iPhone 18 Pro pages | None, only the wattage |
| Apple’s current 60W-class adapter | 40W Dynamic Power Adapter with 60W Max |
| Footnote on that adapter’s store page | Says it was used for iPhone Duo battery testing in July 2026 |
| Adapter price | Not published in any of ten Apple storefronts checked |
| Wireless alternative | Up to 50 percent in 30 minutes with a 35W adapter and MagSafe |
| In the box | iPhone with iOS 27 and a 1 m USB-C cable, no adapter |
One adapter, two wattages in its own name
The product name does the work of a spec sheet: 40W as the figure Apple leads with, 60W as a maximum. Apple does not publish, on the iPhone 18 Pro pages or in the September 9 press releases, which of those two numbers the 15-minute claim depends on, or what conditions move the adapter from one to the other.

That leaves buyers matching a claim written in watts to a product named after two of them. The safe reading is the one Apple states on the phone: a 60W adapter over USB-C. Our walk through the 45-hour battery claim covers how the charging lines sit alongside the hour ratings.
The footnote points at a different phone
Apple publishes separate wired charging claims per model, and the adapter each one names is not the same. The iPhone Duo, the phone the adapter footnote mentions, is rated five minutes slower than the iPhone 18 Pro to the same 50 percent, with an adapter Apple describes only as 60W-capable.
| Model | Apple’s wired claim | Adapter Apple names |
|---|---|---|
| iPhone 18 Pro | 50 percent in around 15 minutes | 60W USB-C, sold separately |
| iPhone 18 Pro Max | 50 percent in around 15 minutes | 60W USB-C, sold separately |
| iPhone Duo | 50 percent in around 20 minutes | 60W-capable |
| iPhone 17 Pro and Pro Max | 50 percent in 20 minutes | 40W |
| iPhone 17 | 50 percent in 20 minutes | 40W |
| iPhone Air | 50 percent in 30 minutes | 20W or higher |
Read down that column and the naming is inconsistent rather than wrong: a wattage for the 18 Pro, a capability for the Duo, a different wattage for last year’s Pro models. The Duo against the iPhone 18 Pro Max comparison shows how much else the two phones share, which makes the five-minute charging difference harder to explain from published material.
No price, in ten storefronts
Apple’s accessory listing for power and cables returned nothing usable in the US or the UK, the individual adapter and MagSafe product pages render their prices after the page loads, and none of the five September 9 press releases lists a charger price. The result is a required accessory with no published cost anywhere, on the day pre-orders open. Our price breakdown covers what the phone itself costs per tier.
What Apple has not said
- A price for the 40W Dynamic Power Adapter with 60W Max, in any storefront checked.
- Which adapter model the iPhone 18 Pro 15-minute claim was measured with.
- What moves that adapter between its 40W figure and its 60W maximum.
- Why the iPhone Duo, on the same 60W-class adapter, is rated five minutes slower to 50 percent.
- Whether any third-party 60W adapter satisfies the claim, and which cable it needs beyond the 1 m one in the box.
- Any charging figure above 50 percent for either iPhone 18 Pro model.
Pre-orders for the iPhone 18 Pro and Pro Max open today, Saturday, September 12, at 5 a.m. PT, which is 12:00 UTC, and the phones arrive Friday, September 18. iPhone Duo pre-orders follow on Friday, October 16 with delivery from Friday, October 23, so the phone in the adapter’s footnote reaches buyers five weeks after the phone that needs the adapter.
