Four-adapter USB-A and USB-C kit

This four-pack contains two USB-A male to USB-C female adapters and two USB-C male to USB-A female OTG adapters. The set bridges legacy USB-A peripherals and modern USB-C hosts for charging and data syncing. It targets users who mix older flash drives, keyboards or mice with newer phones, tablets and laptops. Buyers needing video output or laptop-power delivery should look elsewhere.

Up to 10 Gbps USB 3.0 throughput

Both adapter types operate at USB 3.0 speeds, reaching a maximum of 10 Gbps with compatible devices. Large photo libraries or video clips move noticeably faster than over USB 2.0 links. The adapters do not support Thunderbolt, DisplayPort or HDMI signalling, so external monitors cannot be driven. They also lack Power Delivery negotiation, limiting charging to basic rates.

Passive aluminium bodies run cool

Each adapter uses an aluminium alloy shell that dissipates the tiny heat load from data transfer and standard charging. No active cooling is present, so operation stays silent. The slim profile sits flush against ports without blocking neighbours, and the lightweight 0.0440924524 lb total mass adds negligible strain to device sockets.

Questions about this item

Will the USB 3.0 adapters work with my older USB 2.0 flash drives and cables?

Yes, the USB 3.0 adapters are backward compatible with USB 2.0 devices, so your existing flash drives and cables will function at USB 2.0 speeds.

How can I confirm the 10 Gbps transfer rate is active after connecting the adapter?

Check the device properties on your computer to verify a USB 3.0 or SuperSpeed connection, then run a file transfer test with a compatible drive to measure real-world throughput.

The pack lists 2 USB-A to USB-C and 2 USB-C to USB-A adapters — are any cables or power bricks included?

No, the package contains only the four adapters; any USB cables, chargers or power bricks must be purchased separately.
