Micro USB OTG adapter with power port

This Micro USB OTG adapter adds a female USB port and a separate micro USB power input to phones, tablets and other devices that support USB OTG. It lets you connect keyboards, mice, card readers and flash drives while supplying external power to the attached peripheral. The adapter is intended for users who need to expand connectivity on mobile devices without relying on the host for power.

Thermals noise and power draw

The adapter draws no measurable power of its own and produces no heat or noise during operation. Power for connected storage devices must come from an external charger plugged into the dedicated micro USB port. The host device is not charged through this adapter and its battery is not drained by the adapter itself.

Upgrade from basic OTG cables

Standard OTG cables without a power port cannot run bus-powered hard drives or multiple peripherals at once. This adapter solves that limitation by adding a dedicated power input, making the jump worthwhile when you need to use mechanical drives or power-hungry accessories with an Android or Windows tablet. It does not help if your device lacks OTG support entirely.

Questions about this item

How do I plug this Micro USB OTG adapter into my phone and add external power?

Connect the Micro USB male end to the device, attach a charger to the separate Micro USB female port, then plug your USB keyboard, mouse or flash drive into the standard USB female socket.

Will the separate Micro USB power port wear out or need replacement?

The adapter has no moving parts or serviceable components; the power port is a fixed soldered socket that lasts as long as the cable itself.

What stops a mobile hard disk from working through this adapter during long transfers?

The mobile hard disk requires its own external power supply and must be formatted FAT32; without both it will not stay powered under sustained use.
