Q
How long does the battery last?
A
It last all day for me about 12 hours 
Q
Is it compatible with sony a7iii??
A
Yes, it will fit any Sony e mount body, either full frame (a7..., a9...), or aps-c (like a6500, etc) 
Q
dose it have a externel power port and if so is 6v or 12 v ?
A
Yes it has a 12 volt power port on the bottom. But it takes a 4.0x1.7mm plug. Most external battery packs are 2.1... I had to get a 2.1mm to 4.0x1.7 adapter from Amazon to use my Stealth Cam 12v solar battery pack. I love it! Radio Shack has them cheaper if you are lucky enough to have one still in your area. 
Q
Does this adapter allow for canon fd lenses to focus to infinity on sony e-mount mirrorless cameras?
A
yes, i had no problems with infinity focus with this adapter. the only FD mount lens i use anymore with my sony is a vivitar 20mm, and i pretty much only shoot infinity focus with it. 
Q
I currently own 3 a-mount lense (from a sony a230) just bought a sony a5000, which is an emount. Will this adapter fit my old lenses to my new camera?
A
No, this adapter is for the older manual focus Minolta Rokkor MC and MD lenses. If you want to autofocus and aperture control you will need the Sony LA-EA4. (the lower cost Sony LA-EA3 will electronically connect A mount lenses but you will have to manually focus.)
