I prefer magnetic charge cables, but they have one key challenge: They get knocked off easily, even with the weight of the cable itself, so I went hunting for a solution.
I found the bike holders as a starting point, added a cable holder, a notch for the cable and a backplane to enable a pair of these to be kept handy and charged (you need to be using rechargeable AAA batteries)
I'm taking the 3M double sided command strips approach, but some may prefer to screw this in place.
