It seems everyone is selling bits & pieces for our phones.
The black & white box is my (now) old powerbank.
The new toy is the USB/iPhone cable.
Without power, nothing unusual... BUT... WITH power, it lights up. BUT that's not all... The colour 'bleeds' down the cable!! The cable at the power source continuously cycles through the whole spectrum between red & blue and back again, which travels in sequence down to the phone plug. A bit like those solar-powered colour-changing garden lights. And it works regardless of whether it's attached to my phone or not (as you can see -- no phone attached)!
(The 'powered' pix are slightly blurred if you enlarge them, because my camera has difficulty focusing in dim light
