USB 2 specification is 5 V @ 500 mA maximum. USB 3 specification is 5 V @ 1.5 A maximum. and obviously there's all the new power delivery standards that require ICs to do handshakes and other crazy shit to negotiate the proper voltages and current limits.

does USB 3 (5 V, 1.5 A) require a handshake or an IC?

or can i just swap out the USB connector on my schematic for a USB 3 connector, plug it into an off the shelf """USB 3""" charger, and have no issues negotiating and utilizing the full 1.5A (limited by the TP4056's 1A maximum)?
