Two-pack magnetic USB-C adapters

This two-pack supplies a pair of straight magnetic USB-C gender changers that convert a male port to a female receptacle. They are aimed at laptop users who want to reduce wear on built-in ports while keeping a secure, quick-release connection for charging, data and external displays.

USB4 and Thunderbolt limits

The adapters operate within the USB4 specification and support Thunderbolt 3 and 4 hosts, capping data throughput at 40Gbps. Video output reaches 8K resolution at 60Hz when the host, cable and display all meet the same standard, so older USB-C ports will not deliver those rates.

140W power delivery ceiling

The single specification that decides suitability is the 140W Power Delivery rating, which matches the highest-demand USB-C laptops such as MacBook Pro models. Devices that require more than 140W cannot be charged through these adapters.

Questions about this item

Should I buy the single or the two-pack for my setup?

The listing supplies a two-pack containing two identical magnetic USB-C adapters and two cord straps, so you receive both units in one purchase.

What does the 40Gbps figure mean when I plug this into my laptop?

It indicates the peak data rate the adapter can pass when used with a USB4 or Thunderbolt cable and a host that also supports 40Gbps; actual speed will match the slowest link in the chain.

Which standard does the USB4 label cap in practice?

The adapter is built to the USB4 specification and works with Thunderbolt 3 and 4 hosts, carrying up to 40Gbps data, 140W power delivery and 8K video at 60Hz through the same connection.
