Versatile OTG adapter for Android and USB-C devices

This Hetai Tech cable connects Micro USB and USB-A ports, letting Android phones and USB-C laptops use flash drives, keyboards, mice, gamepads and card readers. It is intended for users who need quick peripheral expansion without drivers. Buyers whose devices lack OTG support or who want a charging cable should look elsewhere.

Simple plug-and-play connection with one caveat

The 18 cm cable plugs directly into the host port and the USB-A peripheral, requiring no software installation. Aluminium connector housings add durability for frequent insertion. The only common issue is attempting to use the adapter for charging, which the supplier advises against because it is designed for data transfer only.

USB 3.0 interface limits speed to 5 Gbps

The adapter follows the USB 3.0 standard, giving a maximum theoretical throughput of 5 Gbps — ten times the 2.0 rate. Actual transfer rates depend on the connected drive and host controller, so sustained speeds will be lower. The short 7.1-inch length keeps signal loss minimal but restricts placement options.

Questions about this item

How can I confirm the OTG cable is working after I plug it into my phone?

Connect a USB flash drive or keyboard; if the device appears in your file manager or the keyboard types immediately, the OTG link is active.

What comes in the package and what must I supply myself?

The box contains the 18 cm Micro USB to USB A OTG cable only; you provide the phone, tablet or laptop and any USB A peripherals such as drives, mice or card readers.

Which version should I choose for the fastest file transfers?

This model uses USB 3.0 for up to 5 Gbps throughput, which is 10x faster than USB 2.0, so select it when speed matters.
