There are powered hubs of up to 100Watts. Power is from a laptop type power supply but they can output lots of power on lots of ports.The input power is my one disappointment with the hub. USB 3 spec calls for 900mA per port. Unless one finds a PSU that will deliver more that 3A at 5v without using PD, the power input for the hub will be limited to 3A, which is an average of 750mA per port. So you could get the full rated USB 3 power, only if you limit the downstream to 3 of 4 ports. Personally, I think the RPT missed a bet (even at an increase in price) of not putting a PD "handshake" into the hub to allow it to accept the full 5A from a Pi5 PSU. Perhaps a future iteration will fix this.
But they aren't really in a Raspberry Pi sort of price range.
Regard a PD handshake in the hub, is there an hub IC that does this ? Might be the issue.
