Apple’s new 40W charger has a secret mode for faster iPhone 17 charging

Apple introduces a lot of exciting products on Tuesday. But wait! There is one more thing, one thing that Apple didn’t show.

Apple has released a new 40W Dynamic Power Adapter with 60W Max charging. For $39 (it’s not available in the U.K. yet), this charger can add a 50 percent charge to the iPhone 17 and 17 Pro battery in 20 minutes, and that 10 minutes of charge results in about 8 hours of video playback. This wired charger can adjust its charging output to a maximum of 60W for a short boost in charging speeds.

Fast-charging on the iPhone Air is slower (50 percent in 30 minutes) and only requires a 20W or higher wired charger.

Remember, Apple does not include a charger with the iPhone. If you already have a USB-C charger, you can use it with the iPhone 17, but Apple specifications state that fast-charging is only possible with a 40W adapter or higher charger. It’s not clear exactly what’s at play here, but Apple implies that the 60W boost will enable faster charging than simply using a standard 40W adapter.

Of course, Apple lists the 40W Dynamic Power Adapter with 60W Max as compatible with all USB-C devices, but the real benefits will be seen by iPhone 17 users.
