SKU CH-3V3V-G1C0F

  • USB 3.1 Type-C connector enables fast data transfer

Purpose and Audience

This USB 3.1 Type‑C to USB 2.0 Female OTG cable connects legacy USB‑A peripherals such as flash drives or portable hard disks to modern USB‑C laptops, tablets or phones. It is intended for users who need occasional data access from older devices on newer hosts. It does not serve buyers who want to charge the host laptop, tablet or phone through the same connection.

Capacity and Headroom

The link operates at USB 2.0 speeds, so file transfers from mechanical drives or large flash sticks will be limited to that bandwidth ceiling. The supplementary power lead supplies extra current for bus‑powered peripherals that exceed the host port’s own output. It cannot support USB 3.1 throughput for attached devices because the female port is wired for the 2.0 specification only.

Thermals Noise and Power

The cable draws no active cooling and produces no audible noise in normal use. Power for the attached peripheral is sourced from the host’s USB‑C port and the auxiliary power lead, keeping the adapter itself passive. There is no internal circuitry that generates measurable heat during typical data‑transfer sessions.

Questions about this item

Will my USB 2.0 flash drive work at its normal speed when I plug it into the USB 2.0 female OTG port on this cable?

The female port is USB 2.0, so a USB 2.0 flash drive will operate at its standard 2.0 speed when connected through this adapter.

How can I verify the cable is delivering the extra power my external hard drive needs?

Connect the supplementary USB power lead to a charger or powered port; the external hard drive should spin up and appear on the host device without a low-power warning.

Does the package include a separate power adapter for the extra USB power cable, or must I supply my own?

The box contains the USB-C to USB 2.0 female OTG cable with an attached extra USB power lead; a USB power adapter or powered port is not included and must be provided separately.
