What to know before buying
Listing details to confirm
Listing details are inconsistent: the title and feature text describe two packs of each adapter direction, while the specifications report one port and do not establish the supplied quantity. Dimensions are also listed as 15 x 14 x 7 millimetres in details but 17.6*14.6*7.2mm in the feature text. Confirm the selected listing's contents and which dimensions apply. The 10Gbps figure is conditional on device support and a data cable no longer than 1 metre.
Who is it for?
A good fit for
- People needing compact adapters to connect USB-A accessories with USB-C phones, tablets or computers.
- Buyers whose devices and data cable support the claimed 10Gbps transfer rate.
Less suited to
- Anyone needing a multi-port hub or a guaranteed 10Gbps connection regardless of host device and cable.
