Dual-Slot USB 4.0 Card Reader

This BESIGN reader accepts SD and TF cards at the same time and moves data at up to 312 MB/s over a USB 4.0 link. A 1 GB file transfers in roughly 10 seconds. The 90° angled connector keeps cables tidy and reduces strain on the port during long transfers. A built-in magnet holds the reader against compatible phones for hands-free operation.

Check Your Setup Before Ordering

Verify that your device has a USB-C port that supports USB 4.0 or at least USB 3.2 to reach the quoted speed. Confirm your SD or microSD cards are SDXC, SDHC, SD, TF, Micro SDXC or Micro SDHC formats. On Android phones or tablets, allow the file manager to run in the background so the reader is not shut down by the system. Ensure cards are fully seated before starting a transfer.

Ideal For Mobile Creators; Not For Legacy USB-A Only

Photographers and videographers using iPhone 15 or 16 series, recent Samsung Galaxy S models, Huawei Mate or P series, or recent iPad Pro, Air and Mini models will appreciate the magnetic mount and fast offload. Laptop users with USB-C on MacBook Pro, Air, Surface, XPS, Spectre, ThinkPad X1 Carbon or MateBook also benefit. Buyers whose only ports are USB-A or who need a reader for older card formats not listed should look elsewhere.

Questions about this item

Does the BESIGN 4870 include any cables or do I need to buy a USB 4.0 cable separately?

The reader has a built-in 90° USB-C connector so no separate cable is required; it plugs directly into the host port.

Is the 312 MB/s rating the speed I will see with every SD or TF card I own?

312 MB/s is the interface ceiling; actual throughput depends on the card's own rated speed, so slower cards will transfer at their lower limit.

How does the magnetic attachment work with an iPhone 16 when I am transferring 1 GB files?

The internal magnet holds the reader to the back of an iPhone 16 series phone, leaving both hands free while the USB 4.0 link moves a 1 GB file in roughly 10 seconds.
