USB 3.0 Y Cable to B Female with USB 2.0 Power Leg

This is the power-boost Y in its B-female form: the USB 3.0 A male end plugs into the host and carries data plus primary power; a supplemental USB 2.0 A male taps a second port for extra current only; and the USB 3.0 B female end receives the square-plug lead of a printer, scanner or external drive whose power draw outruns a single port. Nickel-plated contacts in a blue moulded body, transfer speeds up to 5.0 Gbps on the 3.0 lane, and compact enough to hide behind a desk.

An honest note on shape and use: B female is the less common Y termination — it suits devices whose own B-male lead is fixed or too short, letting the Y act as a powered coupler. The USB 2.0 leg is power-only and carries no data. Confirm your device presents a B male plug before ordering; the A-female Y variant covers everything else, and the adapter-series family (AM/AM, AM/BF, BM/BF and the full matrix) lives elsewhere in this shop.
