USB OTG with occasional charging
Some phones / tablets allow battery charging during USB OTG mode. I''ve seen documentation for two different schemes. 1) Normal OTG mode (no battery charging): ID pin is connected to the ground pin.

It will just make much more sense to buy a Type-C PD charger if your devices support it, rather than still dealing with the problem of which USB adapters you can use to convert to Type-C
How can I tell charge-only USB cables from USB data cables?
I''d throw out all the "charge-only" cables. As the other answers have indicated, charging over a cable with the data lines disconnected is slow at best, and overloads the port at worst. If you want to inhibit
