Multi-Connector Card Reader

This compact reader combines a USB 2.0 Type-A plug, a Micro-USB connector and a USB Type-C connector in a single black housing. It accepts full-size SD, SDHC, SDXC and MMC cards in one slot and microSD, microSDHC and microSDXC cards in the other. The device is aimed at users who move media between legacy USB-A computers, Android phones with OTG support and newer USB-C laptops or tablets.

Build Integration

No external power supply or driver installation is required; the reader draws power directly from the host port. Its three built-in connectors eliminate the need for separate adapters or dongles when switching between a desktop PC, a MacBook Pro and an OTG-capable Android phone or tablet. The USB 2.0 interface determines the maximum transfer rate, so high-speed UHS-I cards will operate at the bus limit rather than their rated speed.

Supported Cards And Limits

The package contains only the reader itself; no cables, cases or software utilities are bundled. Compatibility extends to SD, SDHC, SDXC, MMC, RS-MMC, microSD, microSDHC, microSDXC and UHS-I cards. The unit does not work with iPhone or iPad devices, so buyers needing direct iOS connectivity must look elsewhere.

Questions about this item

What speed limit does the USB 2.0 interface impose on sustained transfers?

The USB 2.0 interface caps sustained throughput at the bus maximum, so the port becomes the bottleneck before most cards reach their rated speed.

Does the reader heat up or make noise during all-day use?

It has no moving parts and draws power only when a card is inserted, so it stays cool and silent even during continuous operation.

What must my Android device already support for the Micro-USB or Type-C plugs to work?

Your phone or tablet must support USB OTG; without OTG the reader will not be recognised.
