Which iPhone Do You Have?
- iPhone 15 / 16: Limited to USB 2.0 (60 MB/s). Don't buy expensive high-speed readers; you won't see the benefit.
- iPhone 15 Pro / 16 Pro: Supports USB 3.0 (up to 280 MB/s real-world). You need a UHS-II reader and card to reach these speeds.
- iPhone 16 vs 15: Same USB-C connector, same speed tiers. Reader recommendations are identical for both generations.
Protect Your Port
Avoid rigid "Stick" dongles. If it plugs directly into the phone like a thumb drive, one accidental bump can snap your iPhone's USB-C port internally.
Always choose a reader with a flexible cable.

Frequently Asked Questions
Why does iPhone limit USB-C speeds?
iPhone 15 and iPhone 16 standard models use a bottleneck controller that limits USB to ~60 MB/s. iPhone 15 Pro and iPhone 16 Pro models use USB 3.0 for full-speed access (~280 MB/s real-world). It's a hardware limitation of those models. The reader recommendation is the same across both generations.
Can I charge my iPhone while using a reader?
Not simultaneously. iPhone only has one USB-C port. However, you can plug into power after transferring files. Most transfers complete in minutes, so it's rarely an issue.
Will a flexible cable reader damage my phone?
No. Flexible cables reduce stress on the port by absorbing physical impacts. This is why Apple's official reader uses a cable, not a rigid connector.
Why don't I recommend the Anker PowerExpand here?
Anker PowerExpand is a good reader, but it's a dual USB-C/USB-A dongle with a rigid design. For iPhone specifically, the cable-style readers (Apple, SanDisk, Transcend) are safer and better optimized.
