What to know before buying

Listing details to confirm

The 10Gbps figure is a stated maximum, not a guaranteed transfer rate. The connected device must support that speed and the connected cable must not exceed 1m. The listed dimensions are 14.5 x 8.3 x 0.9 centimetres, while the feature copy describes a 10cm cable, so the overall dimensions and cable length are not clearly reconciled. Compatibility lists vary across listing sections and include differing device generations. The details also list 20 Volts, 2 Amps and a Type C power plug, which are not clearly explained for this adapter. Confirm the exact device compatibility and relevant specifications before buying.

What’s in the box

Included
  • 1 x USB C to USB 3.0 Female OTG Cable

Who is it for?

A good fit for

  • People who need to connect a USB-A peripheral to a compatible USB-C phone, tablet or computer.
  • Buyers looking for a short OTG cable to use with memory sticks, external drives or a compatible dock.

  • Buyers who need a USB-C-to-USB-C connection rather than USB-C to USB-A.

Customer feedback highlights reported compatibility with memory sticks, external drives and DisplayLink docks, along with ease of use, build quality and fit. These reports suggest practical appeal for basic peripheral connections, while the listing's speed claim still depends on compatible devices and cabling. The overall rating distribution is mostly five- and four-star, but ratings alone do not establish performance in every setup.

Positive themes

  • Customers report successful use with memory sticks, external hard drives and DisplayLink docks.
  • Feedback describes straightforward setup, solid build and a fit that can pass through some device case openings.
