Most multiport USB power supplies share power between ports.
But as they usually have a max input power lower than the max total possible output, they re-negotiate power levels when a port status changes, which can cause a small power glitch.
It’s not a problem for devices with a battery like phones or tablets.
But it reboots Raspberry PIs and devices connected to powered hubs.
For now, the best I could find is the Anker 24W 2 ports (equal to 2*12W out).
But It’s quite outdated.
Did you check the link?
There is GaN chargers on that product page and 150W divided over 5 ports means 30W per port, which should be more than enough if you do not try to charge large laptops on it too.
My 80W 5 port PD charger handle 2 small HP laptops running as servers, 2 Raspberry 4B+ and a Sonoff RF Bridge 433. It does it without a glitch and have been for around an year now.
What you don’t understand is that if a charger renegotiate power, it usually renegotiate all ports and creates a micro-power cut, which is acceptable for phones and laptops, but not for raspberries and associated switches. That’s why I’m asking for static power allocation per port.
Well, the one version I use of their product have no issues with powering my raspis even when I reboot or shutdown and later restart my laptops connected to it.
