Q: 9. What kind of connector is on the end of the cable?

Q: 10. On a Canon M5, you can't operate the camera without closing the battery door. As far as I can see, there is also no cable outlet of any kind. How is this product physically able to work?

A: You should be able to make it work with the M5 without keeping the battery door open. Canon sells a similar coupler to this for the M5 that plugs into the wall. Ours is meant to plug into a USB battery pack.On the bottom of the inside of the door, do you see a silver piece with a round hole? The version I've found has a number 3 on that rubber piece, but yours may be different. That rubber piece should pop out and you would plug the cable into the coupler through that hole.
