Question about Pulox Checkme O2

Correction: I have taken another look at the Pulox plug. It appears to be a micro HDMI plug. The external dimensions (5.83x2.2) are exactly right and you can see the 19 holes under the magnifying glass. I can't say anything about the wiring to the USB plug (Pulox charging cable).

Presumably mini USB type B
