Google search: coolpad "tracker" charging cableI found:https://ebya.io/3Fgc
we use this to automatically reset equipment: https://amzn.to/3AgAOegNetReset-Digital Timer Outlet
We bought the 4 pin charge cable from Ebay and it works fine. Charging only uses 2 pins and maybe the other pins are to program or update firmware on Tracker. Does not seem to be any other source.
