has anyone experience in using a powered usb hub to power a raspberry pi 4 and (in my case) two 2.5 inch usb hard drives or similar devices? I can not power them via the usb ports of the pi (not enough current), so I decided to buy an active usb hub. To reduce the amount of power supplies I thought it might be possible to plug the Pi into the hub as well.
Unfortunally I only found hubs that support max 2,4A per port (for example this one https://www.amazon.co.uk/dp/B07RS31T3Y/ ... UTF8&psc=1) and the red port is according to the description for fast charging phones. Are special protocols required that only smartphones and similar devices support?
Usually a RP4 doesn´t need 3A all the time as provided by his psu.
So does anyone know if I can power a RP4 with a hub like this one to run NextcloudPi or will there be problems?
Thank you for your help
PS: I could try to combine two usb ports to get enough current. Any thoughts about this?
