LUOM FX-439 3-in-1 USB 3.1 OTG Kit

The LUOM FX-439 is a compact white card reader with a USB 3.1 Type-C connector. It targets photographers and mobile workers who want to view images from SD, microSD, CompactFlash, Memory Stick, MMC, SmartMedia or xD cards directly on USB-C phones, tablets or laptops without wireless transfer.

Three slots in a single external adapter

The unit combines an SD slot, a microSD slot and a standard USB-A port into one dongle, so legacy flash drives, keyboards or mice can be used alongside memory cards. A direct wired link avoids the dropped frames and latency common with Wi-Fi or Bluetooth offloads, and the plug-and-play design needs no driver installation on supported hosts.

Check your host port and card capacity before buying

The adapter requires a USB-C port that supports OTG or host mode; USB 2.0 Type-C ports will limit transfers to 480 Mbps. Memory cards larger than 64 GB are not supported, so verify your media falls within that limit. Some older tablets or phones with USB-C may not implement the necessary host protocol.

Questions about this item

What does the USB 3.1 interface mean for transfer speed on this FX-439 reader?

The USB 3.1 interface supports up to 5Gbps, so large files move quickly; on USB 2.0 hosts the speed drops to 480Mbps.

What physical slot does the FX-439 need on the host device?

It plugs directly into any USB-C port on phones, tablets or laptops — no extra cables or adapters required.

How do I set up the FX-439 and what step do users often miss?

Insert a card up to 64Gb, connect to the USB-C port and the device recognises it instantly; the common mistake is expecting it to work on a USB-A port without an adapter.
