3-in-1 Micro USB OTG Adapter

The Hetai Tech adapter adds USB On-The-Go capability to tablets and phones with a Micro USB port. It provides one Micro USB female port and two USB 2.0 female ports for connecting peripherals such as a mouse, keyboard, flash drive or game controller. A physical switch selects between charging the host device or enabling OTG data transfer.

Compatibility and power requirements

Verify that your Android tablet or phone supports USB OTG before ordering; the adapter works with devices like the Dell Venue 8 Pro, Galaxy Tab series and Nexus 7 or 10. The Micro USB female port supplies power to the hub only and cannot charge the connected host device. A hard drive cannot be powered through this adapter.

Sustained use behaviour

When the switch is set to OTG the host device receives no charge, so battery level will drop during extended sessions with two peripherals attached. The hub handles simultaneous keyboard and mouse input without interruption. File transfers from a flash drive proceed at USB 2.0 speeds for as long as the host device remains powered.

Questions about this item

What comes in the box with the Hetai Tech 3-in-1 Micro USB OTG adapter cable, and do I need to buy anything else?

The package contains the adapter cable itself with one Micro USB male plug, one Micro USB female port and two USB 2.0 female ports. You only need to supply the peripherals — mouse, keyboard, flash drive or card reader — that you want to connect.

The description mentions a charge/OTG switch; how do I decide which mode to use?

Slide the switch to "Charge" when you want the Micro USB female port to power the phone or tablet; OTG data transfer is disabled in that position. Slide it to "OTG" when you need to use a mouse, keyboard, flash drive or game controller — the host device will not charge while OTG is active.

Can I run a portable hard drive from the two USB 2.0 ports on this adapter?

No. The supplier notes explicitly state the adapter cannot connect a hard disk; it supports flash drives, card readers, mice, keyboards and game controllers only.
