Thanks for your feedback. I took a closer look at the QC technique and found your idea of using a QC tester very good. I ordered 2 of the variants with the slide switch and then optimized them for daily use. First, I removed the output USB socket and soldered a DC cable directly into the PCB. For the 8.3V variant I connected a diode in series. In order to simply fix the PCB in a small housing, I constructed a holder (3D). So that the LED on the tester is visible from the outside, I used a piece of optical fiber. Attached are a few pictures of my construction.
