Review on USB to iPhone Adapter - Plusysee iPad USB 3.0 Female OTG Adapter with Charging Port - Plug & Play USB Camera Adapter for iPhone/iPad - Support Camera, Card Reader, USB Flash Drive - iPhone USB Adapter by Carlos Barete

This article didn't work for my purpose of transferring pictures from an old iPhone to a Windows computer. The Plusysee adapter (and the USB3 male-to-male cable) did not show that it was recognized by either the iPhone or the computer. It may work for other purposes (I don't know) which is why I gave it 2 stars. I will return as unnecessary. I ended up buying a Lightning to USB cable direct from Apple, which was a lot easier and got the job done easily the first time.
