my Smasung Battery pack will charge the the a9, but the a7r2 doesn't even recognize it...does the 7r2 charge through the multiport?
and that was why the 7r2 sucked at motorsports! and why the a9 kills at it!
I just plugged into my a7Rii (no battery grip, mine is a Meike and won't work, however on the a9 I have OEM Sony and it will) the OEM A7Rii cable and then plugged into
the Patriot Fuel+ 7800 mAH's 2.5 amp port. I push menu on the a7Rii then half-way depress the shutter. In the upper right side of the LCD screen I see the battery charge
indicator and the 'plug-in' indicator beside it which if I remember correct denotes charging and/or external power source.
USB power is 'on' in the menu selection. OEM cable might be important since it has the extra charging pin.
I just put an almost dead battery into the A7Rii, same setup. Push menu (doesn't matter what menu area you are in), momentarily depress the shutter button and see the battery
icon, in this case battery icon has at most 1 bar but the charging 'plug-in' symbol is beside it.
Do note this. It is an and/or thing concerning the little yellow light right beside the external multipin connector.
When I turn off the camera and the A7Rii via OEM cable into the 2.5a port of the Patriot+ Fuel, now I'm seeing the little yellow light on showing me the camera is now charging the
OEM Sony battery.
