BoxWave miniReader Keychain USB-C OTG Micro SD Card Reader

The BoxWave miniReader solves a narrow, practical problem. The Aula L99 exposes a USB Type-C port, and this keychain-sized OTG adapter turns that port into a Micro SD card slot. Seat a card in the reader, plug the reader into the L99, and the contents of that card become reachable on the device itself, whether that means sharing photos, moving music across, or pulling video off after a shoot. It is aimed squarely at people who shuttle files between a memory card and a device regularly rather than once in a blue moon.

Transfers run over the USB 3.0 protocol, which is the specification that matters most in an accessory like this; a reader limited to older, slower standards turns a large file pull into an exercise in patience. The housing is finished in metallic silver, and the miniReader name is literal. This is an accessory built to disappear onto a keyring, and BoxWave commits to that idea by including a hook and lanyard rather than selling them separately. Setup, per the manufacturer, amounts to plugging it into the Type-C port.

Two caveats deserve attention before ordering. The Micro SD memory card is not included, and neither is the L99 itself, both of which BoxWave states plainly in its listing. Compatibility is described in terms of the L99's USB Type-C port, so anyone hoping to share one reader between that device and an older USB-A laptop should budget for a second adapter.
