Not really. Protocols like USP-PD or QuickCharge require a direct connection between the power source and the device being charged, were USB-PD requires USB-C as well. USB hubs are usually not designed to power devices except when they come with their own power supply to make sure that every port can be powered with 4.5 (USB 2) to 9 watts (USB 3). They will most likely only delivery 100 mA per port and refuse any higher requirements. A better choice is to use a charger with multiple ports. Up to 4 ports in a single charger are not hard to find. There are also power banks which provide multiple ports. -- Arno Welzel https://arnowelzel.de
