The new usbc is 40gbps transfer and charges at 240w, but you need a charger that is capable of outputting that and a device that can charge at that and most don’t - not even the new iPhones (not sure about android). I think only the frame laptop can currently charge at 240w. So it’s more future-proofing than anything but the transfer speeds are awesome - but again, depend on your device ports.
