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

It has a kind of clip on the luminaire itself, and can be fastened with a rubber band....
