8-in-1 USB OTG card reader

The Hetai Tech 8-in-1 USB OTG Card Reader connects Micro USB devices to TF and SD memory cards for direct file access on phones or tablets. Its compact 5.5 cm length makes it easy to carry for on-the-go data transfer between storage media and mobile devices. The reader draws power from the host device so no external supply is needed.

USB 2.0 interface limits transfer speed

The reader operates over a USB 2.0 connection with a maximum theoretical throughput of 480 Mb/s, so actual file-copy rates will be lower and depend on the card and host controller. Hot-plug support allows cards to be inserted or removed without restarting the connected device. Large video files will move more slowly than on faster interfaces.

Micro USB connector fits older Android devices

The Micro USB OTG plug is designed for legacy Android phones and tablets that lack USB-C ports, so it will not work with newer USB-C or Lightning-equipped devices without a separate adapter. Buyers with modern USB-C handsets should look for a USB-C card reader instead. The ABS shell keeps weight low for portable use.

Questions about this item

Which 8-in-1 version of this card reader should I choose?

The single 8-in-1 model covers Micro USB OTG, TF and SD slots in one 5.5 cm black or white ABS body, so no capacity or version choice is needed.

What does the 480 Mb/s headline speed mean when I plug this into my phone?

It is the theoretical USB 2.0 ceiling; real-world transfer rates will be lower and depend on the card and host device.

Which interface standard does the Micro USB OTG port use, and what does it cap in practice?

The port follows USB 2.0 OTG, limiting throughput to 480 Mb/s and requiring no external power.
