Question about knog. Plus

Hi. You can plug the light into a PC or power supply like a USB stick for charging. Just take it out of the magnetic holder and there are copper contacts on the opposite side of the on/off switch. Does it work? Kind regards

I see the stick now but my cables don't fit does it need a special cable it's plastic all round

sorry already found thanks

I can see the copper contact (the round hole) but it's not like a USB stick?
