Micro USB OTG card reader dongle

This Micro USB OTG dongle combines a card reader with a USB 2.0 adapter in a single compact unit. It accepts both SD and TF cards for direct access on compatible phones or computers. The 2-in-1 design removes the need for separate cables or readers. It suits users who transfer photos or files from memory cards to mobile devices without a full-size USB port.

USB 2.0 transfer behaviour under sustained use

The USB 2.0 interface limits throughput to its rated 2.0 specification during extended copy sessions. Large batches of images or video will move at this steady rate rather than at burst speeds. The adapter draws power from the host device, so prolonged transfers depend on the phone or computer maintaining sufficient bus current. It is not suited for workflows that demand higher sustained bandwidth than USB 2.0 provides.

Questions about this item

Does the USB 2.0 interface on this dongle draw noticeable power from my phone during all-day use?

The USB 2.0 connection uses very little current, so it will not drain a phone battery significantly even when a card is inserted and accessed continuously.

What must my phone already have for this adapter to read an SD or TF card?

Your phone needs a Micro USB port that supports USB OTG; without OTG support the adapter cannot communicate with the memory card.
