“The hub is plugged into a fast charger for my Samsung Galaxy S8. It seems the charging is very slow with either the Wireless charger or the Type C connector to the phone. Is there a reduction of power/voltage to the two ports used?”

The problem is going to lie within the power output of the hub. It is A 5V, 500 mA/port. 500mA is nothing. By today's standards it's extremely slow for charging. When buying a hub, use one that is externally powered (separate cord that plugs into the wall). Or use a hub that has a higher power output. The problem is these hubs that connect to your laptop usb port are very underpowered. USB ports on your laptop are not supposed to carry a high power output anyway so the hub that connects to a usb port only (and not plugs into a wall) will not be spectacular either.
Sorry, there was a problem. Please try again later.My understanding the ports are geared to a certain speed and if you have a faster than what is on the port it's only going to use the speed of the ports
Sorry, there was a problem. Please try again later.ANY port that is shared will have a reduction in power. Your power supply puts out "X" amount of power. The first item plugged into it will receive ALL of that power, less the loss of conversion and transmission. When you plug in a SECOND item, the amount of power from the power supply remains the same, with the exception of the power loss by wire resistance due to the increased current. That is why a higher output charger comes with the "Smart" phone than comes with the older "Flip" phones. If the device is in "reduced power mode" there is more current available to charge the battery than there would be if you were using the phone actively. The voltage remains very close to the same - there is "SOME" voltage loss due to the resistance of the wires with a higher current load. The problem lies with the CURRENT output capability of the power supply, that is the limiting factor.
