Three-adapter pack for USB-C hosts

This three-pack of black USB-C to USB-A converters lets a USB-C laptop, tablet or phone accept standard USB-A flash drives, keyboards, mice or hubs. Each adapter works as an OTG host, so no driver installation is required — just plug in and use. The set is aimed at anyone who still relies on legacy USB-A peripherals but has moved to USB-C only ports.

Sustained 5 Gbps transfer without throttling

Rated at USB 3.0 speeds up to 5 Gbps, the adapters maintain that throughput during long file copies rather than dropping back after a short burst. Aluminium alloy bodies act as a heat path, keeping the controller cool enough to sustain the rated bandwidth across multiple gigabytes of video or project data. No active cooling is needed and no performance dip appears in typical desktop workloads.

Aluminium shell with integrated key-ring loop

Each converter is machined from aluminium alloy instead of plastic, giving a rigid feel and resisting bend stress when plugged into a tight port. A moulded key-ring loop is built into the housing, so the adapter stays on a keychain or bag strap and is less likely to be misplaced. The compact form factor sits flush against the device, leaving adjacent ports free for other cables.

Questions about this item

Does the aluminium housing of these converters get warm during continuous data transfers at 5 Gbps?

The adapters are passive metal shells with no active components, so they do not generate noticeable heat even during sustained USB 3.0 transfers at 5 Gbps.

What must my host device provide for the OTG function to work with a flash drive?

The host needs a USB-C port that supports USB On-The-Go; the adapter itself only passes the signals through.

Will a USB 2.0 flash drive plugged into this adapter work at USB 2.0 speeds on my 2016 MacBook?

Yes, the adapter is backward compatible and will negotiate USB 2.0 speeds with older peripherals on a 2016 MacBook.
