Which kinda makes sense. I was interested in Andy Smith's comment about power/data usb cables. I'm dumbfounded how GaN chargers got into this. My question was actually non-rhetorical. Someone said all modern charging cables support data transfer. Where can I acquire one that doesn't? I guess I'll have to figure it out by myself. > Cheers
