I also had this problem when trying to power my Star Adventurer with my nice 22 Ah Ravpower USB powerpack. Apparently, the mount draws little power and the powerpack shuts down after a while, thinking "there is nothing to charge"... Looks like most modern powerpacks have this threshold minimum current to stay alive... Obviously, a fast solution is to connect more things at the same time (a USB lamp, etc.) Apparently, there are some powerbanks around that have the option of "always on" (such as the Voltaic), but I discovered that the Amateur Radio Shop Sotabeams UK sells a little cheap adjustable "pass-through" device that cures the problem. I bought it and it works beautifully https://www.sotabeams.co.uk/usb-battery-pack-keep-alive-load/ Clear Skies!
