I see that 11-in-1 hub that you show has a PD USB port, so you CAN charge your MacBook through that hub, while you have other devices connected, so I suspect that if you want to connect two spinning HDDs, like you mentioned in your OP, then connecting the charger through the hub (of course the hub is connected to your MacBook), you should be good. That probably does not make the hub a powered hub, but the power available through the PC USB port should be sufficient for any normal connected devices, and charge your MacBook at the same time -- a good solution when your MacBook only has the one port.
