How long does it take for a camera to recognize that a solar panel is plugged into it?

No, tbh, the representative I spoke to didn’t seem to have a good handle on things. She also took my info and assured me she would send me the little bracket that secures the solor panel plug into the rear of the camera (it was missing from my package). It has not arrived yet, and I am thinking it is not coming aby time soon, if at all. Very happy with the charging of the panel though. My batteries are always close to 100% charged.
