USB-C and USB-A card reader

The LUOM YC-320 is a compact 2-in-1 card reader with dual USB-C and USB-A connectors. It suits photographers, videographers and mobile workers who move SD and microSD media between cameras, Android devices with OTG, laptops and desktops. The reader requires no drivers and draws power directly from the host port. It is not compatible with iPhone, iPad or SIM cards.

Thermals noise and power

Passive construction means no fan noise and no moving parts during transfers. The USB 3.0 interface caps bus power at the standard 5 V limit, so the reader adds negligible load to a laptop or phone battery. Heat stays low even when copying large batches of RAW files or 128 GB card contents. Backward compatibility with USB 2.0, 1.1 and 1.0 ports keeps it functional on older hubs.

Build fit and freedoms

Two slots cover SDXC, SDHC, SD, MMC, RS-MMC, microSD, microSDXC, microSDHC and UHS-I formats in a single dongle. The tiny footprint leaves adjacent ports free on tight ultrabooks or hubs. OTG support turns an Android phone or tablet into a host for offloading footage in the field without a computer. Thunderbolt 3 ports accept the USB-C connector directly, removing the need for a separate adapter.

Questions about this item

How do I connect the YC-320 to my Android phone for OTG file transfers?

Plug the USB-C connector into a phone that supports OTG; the reader draws power from the port and mounts the SD or Micro SD card automatically.

Will the card slots wear out after repeated insertions?

The slots are moulded from high-grade plastic rated for thousands of cycles; keep them free of dust and avoid forcing cards to maintain reliable contact.

What transfer ceiling will I hit first when moving large video files?

The USB 3.0 interface caps sustained throughput at 5 Gbps, so the bus limit appears before most UHS-I cards reach their maximum read speed.
