Expensive OTG pure USB-C hub, power and storgae attached - storage is detected and phone is charging.[image: 1743104790355-img_20250327_194149116_hdr.jpg] [image: 1743104790419-img_20250327_194153624.jpg]
So the expensive one wins which cost (Amazon -£16) and is TiMOVO branded USB-C braided to 3 USB-C female adaptor.
The medium branded one is by BENFEI and I didn't expect it to work at all according to Amazon, but it was either charge or storage, not combined.
The really cheap one was a dud on this device as no storage was detected at all.
