Does USB-C hub need external power?
If it wants to offer downstream USB-C ports, or if it wants to accept USB-PD to enable charging the host while in use, then it generally does accept an external power supply. Usually this is optional. Some very large external docks/hubs require an external power supply, though those are usually Thunderbolt 3 docks, not ''merely'' USB-C 3.1/3.2 docks.

I replaced the power supply with an identical one. Both are the 130w brick that came with the docking station. The Docking station passes power through and despite the message, the NIC works, the external monitor and mouse/keyboard works, so the dock is (mostly) OK. In the BIOS, it shows the brick being 130w and connected.
Internal and External Trail Camera Power
Conversely, if the battery voltage exceeds the external power supply by ~0.3 Volts, all of the current for the camera comes from the internal battery. In the range between these limits, where battery and external power supply voltages are within plus or minus 0.3 Volts of each other, current is shared between the two — equally when voltages ...
