3-in-1 Micro USB OTG Adapter Cable 20cm

The Hetai Tech adapter adds a Micro USB female port and two USB 2.0 female ports to phones or tablets that support USB On-The-Go. It lets users attach a mouse, keyboard, flash drive, game controller or digital camera for PC-like file transfers and input. The 20cm black cable weighs 33g and is designed for portable use.

Installation and common issues

Plug the male Micro USB connector into the host device, then set the side switch to the desired mode. In the OTG position the hub enables data accessories but blocks charging through the Micro USB female port; in the Charge position the port supplies power to the hub while OTG data is disabled. Forgetting to flip the switch for the intended task is the typical setup mistake.

Capacity and headroom

The hub comfortably handles low-power peripherals such as mice, keyboards and flash drives simultaneously. It runs out of headroom when bus-powered devices like portable hard drives or high-current accessories exceed the host port's limited output, causing disconnects or unstable operation. The Micro USB female port is strictly for supplying power to the hub itself and cannot charge the connected phone or tablet.

Questions about this item

How can I confirm the OTG function is active after plugging the adapter into my Android phone?

Slide the switch to the OTG position; the micro-USB port stops charging the phone and the connected mouse, keyboard or flash drive should be recognised immediately.

What comes in the box and is any extra cable or power supply required?

Only the 20 cm black adapter cable weighing 33 g is supplied; no additional cable or power adapter is needed because the host device provides power in OTG mode.

Which version or capacity should I choose for connecting a USB 2.0 flash drive and a game controller simultaneously?

This single 3-in-1 model provides one micro-USB male, one micro-USB female and two USB 2.0 female ports, allowing both peripherals to work together when the switch is set to OTG.
