Im very happy with my MS MJ808E but the constant connecting/disconnecting of the wring harness to charge seems to be the "weak spot" in the process. As I cycle in cold climates, the connectors are often difficult to pull apart after a longer ride. I was hoping to use a "Y" adapter as sold by Geoman ($7.99) to leave permanently in the circuit. One side would go to my headlight and the other side I would use for charging. Then if the constant connects/disconnects wear the connectors down, it wont matter as its only wearing the "Y" adapter.
Of course, I would have to waterproof the "open" side of the adapter - thoughts?
