I use multiple RPI5 boards and using a single multi-port USB power supply which doesn't provide 5A per port. Hence, some of my boards complain that power isn't sufficient (tbh, even if one board is connected it sometimes complain about power). I'd like to have a multi-port raspberry pi power supply that is capable of providing 5V/5A to all my boards. Having multiple power supplies isn't efficient because they consume all my power strip ports, not to mention the cost and the space they take.
Are you aware about multi-port USB power supply that satisfies my needs? Is there a way to convert an external power supply to (usually 12 V) to provide multiple USB ports? (I know it must be possible via voltage dividers. But I don't know if it feasible to simply divide the voltage and connect it to multiple two_wire-to-USBC cables.
