Hello, I bought two RTK Surveyors and received them Saturday evening. Put them on poles and they seem to work (haven’t got data yet as my Android refuses to connect to them, buying a new one soon). But Sunday afternoon when I tried charging them one fails to charge while the other has no issue.
Symptoms: power LED single blinks blue when plugged in. USB power meter shows 0.00 amps. When turned on the power light is yellow and the USB power meter registers 0.08-0.13 amps. Thus I believe the battery is at least not draining when connected to power. Inspection of the board reveales no obvious bad component or loose connection.
Attached are images showing one working and the other not working.

Edit: it seems the working RTK-S uses about 0.2 amps when on and connected to USB. So I am not sure I can fully run it via USB battery pack now.
