Has anyone come across a 9v/3a battery usb-pd to run (not charge) the A1, A7sIII etc. I've been searching the web but can't find a 27w power pack. I'm sure other wildlife photographers must be having the same problems with the A1. You sit waiting for hours for the animal/bird to do what you want by which time you've run out of batteries and gone back to your backup DSLR camera/lens, something that seems to happen most days. A couple of small power banks is what's needed.
