Product Purpose

The Hetai Tech 4-Port Micro USB OTG Hub Cable connects USB peripherals to compatible Android tablets and smartphones that support OTG function. It is intended for users who need to attach a keyboard, mouse, card reader or flash drive to a mobile device with a Micro USB port.

Accessory Impact

The hub provides three standard USB ports for peripherals and one dedicated power port that accepts the device's original charger. When the side switch is set to "Charge", the hub can operate in OTG mode while simultaneously supplying external power to connected accessories such as a flash disk or card reader.

Setup Check

Verify that your Android tablet or smartphone has a Micro USB port and supports USB OTG functionality before purchase. The hub cannot power a portable hard disk, so users needing mechanical drive support should consider a different solution. Ensure you have the device's original charger available if you plan to use the simultaneous charge and data mode.

Questions about this item

Will the USB ports on this hub wear out from repeated plugging and unplugging?

The four USB-A ports are standard connectors rated for typical insertion cycles; no user-serviceable parts exist inside the cable.

What stops me from running a portable hard drive through all four ports at once?

The hub cannot supply enough current for a hard disk; the power port only passes external charger current to low-draw peripherals.

Does the hub get warm when I leave a keyboard, mouse and card reader attached all day?

With only low-power devices connected the adapter stays near ambient temperature; it has no active cooling.
