I love the magnetic quick connector idea, thank you Thunder Drones for bringing it to my attention.
I bought 2 sets of 3 pieces in different lengths and currently use it on most of my devices that get charged regularly. The best thing about it is that now one charging block+ one cable can charge my Apple devices, android phone table, DJI remote, DJI goggles and so on.
I don't need to swap the cables because the netdot magnetic end is compatible and will snap to any stub that is in the electronic device. like this
But here is the problem, both end of the connectors are strong magnets and will start collecting metal pieces.
I went to fly my drone. The remote, drone, DJI goggle was in my car's trunk in a cardboard box, the drone in a soft case,
I was trying to connect the remote to my ipad and the two pulled together but it was wobbling and would not connect.
I pulled them apart to find both pieces were full of small black metal shavings. When I got home I looked at my phone's connector, it also had metal shaving that it picked it up somewhere.
Being a magnet it will just keep collecting anything that is ferrous metal, including metal paper clips on my desk- if it gets near it.
Look how the debris started to embed itself into the soft plastic housing that holds the pins that transfer the signal/ electric current. The soft plastic will eventually be destroyed.
Here are some close-up pics. This is after I used compressed air to blow away the debris from the connector end pieces.
