Dual-Slot Card Reader for USB-C Devices

The Wansurs CR034 is a compact USB-C card reader designed for photographers and mobile users who need fast access to SD and microSD media. It accepts SD, SDHC, SDXC, microSD, microSDHC, microSDXC, MMC and RS-MMC cards through two dedicated slots. The device weighs 0.018 kg and measures 0.7874 x 7.2898 x 11.4046 cm.

Check Your Host Port and Card Requirements

Before ordering, verify that your laptop, tablet or phone provides a USB Type-C port that supports USB 3.2 Gen 1 data transfer and USB On-The-Go functionality. The reader draws power from the host port and requires no external adapter or driver installation. Note that only one card slot can be active at a time, so simultaneous copying between two cards is not possible.

Sustained Transfer Behaviour on USB 3.2 Gen 1

The USB 3.2 Gen 1 interface is rated at 5 Gbps, allowing large photo and video batches to move quickly during extended copy sessions. Because the reader has no active cooling, prolonged maximum-throughput transfers may cause the housing to warm slightly, but the metal shielding helps dissipate heat. Performance remains stable for typical professional workflows involving sequential reads and writes.

Questions about this item

Does the CR034 include any cables or adapters, or must I supply my own USB-C lead?

The reader connects directly via its built-in USB Type C plug, so no separate cable is required for Type-C hosts.

Should I choose the CR034 over a single-slot model if I only ever use microSD cards?

The CR034 provides both SD and microSD slots, but only one slot can be active at a time; if you never use full-size SD cards the extra slot adds no benefit.

What does the 5Gbps rating mean when I copy 4K video files to my laptop?

The 5Gbps figure is the USB 3.2 Gen 1 interface ceiling; real-world throughput will be limited by the card's own speed class and typically falls well below that maximum.
