Ports Lifetime
Standard USB connections have a minimum rated lifetime of 1,500 cycles of insertion and removal. USB-C receptacles have a minimum rated lifetime of 10,000 cycles of insertion and removal. This is an industry-standard.
One thing you can do to prolong the lifetime of the ports on your MultiCharger14-2.4A is to use "sacrificial cables" in between the hub and your charging cables so when you repeatedly connect/ disconnect you are only going to wear the cables rather than the hub.
