Frequently Asked Questions
Is the UGREEN 2-in-1 reader compatible with iPhone 15?
Yes. The UGREEN CM185 has both USB-C and USB-A connectors. It works with iPhone 15, iPhone 15 Pro, and all USB-C iPhones using the USB-C adapter with OTG support. For iPhone 14 and earlier (Lightning ports), use a Lightning adapter.
What transfer speed can I expect on MacBook Air?
Real-world transfer speeds are 80-100 MB/s on most MacBook Air models with USB-C ports. Theoretical max is 104 MB/s (UHS-I), but actual speeds depend on the card and MacBook generation. MacBook Air M2/M3 achieves closer to 100 MB/s.
Can this reader handle 4K video from GoPro and DJI drones?
Yes, for standard 4K recording. The 104 MB/s speed works with most 4K cameras recording at 60fps. However, for 4K 120fps or high bitrate formats, upgrading to UHS-II (312 MB/s) readers like the SanDisk Extreme PRO is recommended.
Does the UGREEN reader work with Android tablets and laptops?
Yes, it supports both USB-C and USB-A Android devices. For USB-C Android phones and tablets, use the USB-C end. For older Android devices with USB-A ports, use the USB-A 3.0 end. OTG support is required for phone/tablet usage.
