USB 3.0 OTG adapter for Android and laptops

This Hetai Tech adapter converts a Micro USB port to a standard USB A female socket, enabling OTG connectivity on compatible Android phones and tablets. It also adds a USB A port to laptops for connecting peripherals such as keyboards, mice, flash drives or card readers. The 18 cm cable supports USB 3.0 speeds up to 5 Gbps for fast file transfers. Plug-and-play operation requires no driver installation.

Suits users needing portable OTG expansion

Ideal for owners of OTG-enabled Android devices who want to attach USB flash drives, keyboards, game controllers or card readers while travelling. Laptop users gain an extra USB A port for legacy accessories. Not intended for charging devices, so buyers who need power delivery should look elsewhere. Compatibility depends on the host device supporting OTG function, which is not universal.

5 Gbps bandwidth handles drives and peripherals

The USB 3.0 interface transfers large files from flash drives or external hard drives in seconds, roughly 10 times faster than USB 2.0. Everyday peripherals such as mice, keyboards and printers operate reliably within this bandwidth. Very high-throughput devices like multi-bay RAID enclosures or 4K video capture cards will exceed the available headroom. The short 18 cm length keeps the setup compact but limits placement flexibility.

Questions about this item

My Android phone has a Micro USB port — does it need to support OTG before I can use this adapter?

Yes, the adapter only works when the phone or tablet already provides OTG functionality; without it the USB A female port will stay inactive.

Will this adapter slow down a USB 3.0 flash drive that I normally use on a USB 2.0 laptop port?

The adapter supports USB 3.0 at up to 5 Gbps, so a USB 3.0 drive will run at its full speed instead of being limited to USB 2.0 rates.

After plugging in a keyboard, how can I confirm the adapter is delivering the 5 Gbps link?

The host device will enumerate the connection as a SuperSpeed USB 3.0 link; you can verify this in the device manager or system information on the phone, tablet or laptop.
