If the USB protocol (ie. USB 3.1 gen 2) is not specified it is safe to assume they are USB 3.0 and As far as I know Lightning connectors are USB 3.0.
According to the seller on eBay, the lightning cables he is selling had to use USB-C ports. That's why I didn't buy from him.
You, and apparently the seller on eBay, are conflating USB port
type and the USB
standard. The USB standard (3.0, 3.1, 3.1 GEN 2, 3.2, 4.0) is a function of the number of wires in the and shielding in the cable and
port. The USB port type (A,
A 2.0, A SuperSpeed, B, B SuperSpeed, C, Mini A¹, Mini B, Mini AB,
Micro-A¹, Micro-A super SuperSpeed, Micro-B, Micro-B A SuperSpeed, Micro-AB, Micro-AB SuperSpeed) describes the physical shape of the connector and all of those can be used with more than one protocol and connector type C can be used with every protocol from 2.0 to 4.0 plus Thunderbolt 3 and Thunderbolt 4. The Lightning connector is an Apple proprietary connector for USB 3.0 standard devices.
That is a lot of information to digest and on the theory that a picture is worth a thousand words
this Wikipedia article has an excellent chart of the "Available connectors by USB standard" showing the relationship between connector and standards.
Every USB standard is [b]backward compatible with all of the previous standards[/b], but the device in the loop with the
lowest USB standard sets the maximum data transfer rate.
My reason for emphasizing getting USB 3.1 gen 2 rated adaptors is because that gives you at least the potential for a 10 Gbps cable setup.
