The LarkBox has a fake USB-C socket tbat is not really a USB-C but just a 12V power input shaped like USB-C.
In order to power it with a real USB-C PD or QC charger, a 12V trigger circuit is required and these are available from China for a couple of dollars each. This should have been built in but they cheated and this socket does not support PD or QC or data and video.
So I built my own cables by connecting two cables with a trigger circuit in between. And de-soldered all the unnecessary components from the circuit board to make it compact enough to have a heat shrink tube fit on it.
They work with normal PD or QC adapters as well as with battery powerbanks.
