Mobile expansion hub

This 3-in-1 Micro USB adapter adds two USB 2.0 ports to compatible Android phones and tablets. A built-in switch selects between charging the host device or enabling data connections for peripherals. The compact design suits travel or desk use without adding bulk.

Dual-port flexibility

The switch on the micro USB female port toggles two modes: charge-only for powering the hub, or data mode for active peripheral use. Both USB 2.0 ports operate simultaneously in data mode, letting a keyboard and flash drive work together. The hub cannot power external hard drives.

Everyday file transfer

The adapter handles mice, keyboards, flash drives, card readers and game controllers for moving photos, music and video between devices. It supports USB 2.0 speeds for documents and media libraries. Demands such as mechanical drives or high-power peripherals exceed its capability.

Questions about this item

Will the Micro USB female port on this adapter need replacement if I use it daily for charging?

The Micro USB female port is rated for charging the hub only, not the connected phone or tablet, so its wear depends on how often you plug in the hub power cable.

What limits simultaneous operation when I plug a keyboard and a flash drive into the two USB 2.0 ports?

Both ports share the single USB 2.0 upstream link, so total bandwidth is capped at the 2.0 specification when the two devices are active together.

Does the adapter get warm or draw extra power when a mouse and a flash drive run all day?

The adapter has no active electronics beyond the switching circuit, so it adds negligible heat and only passes the power the two USB 2.0 devices themselves require.
