This is a link to my original setup, which has been updated to LiFePO4 battery type.
The original AGM was 7 years old and lost capacity as lead acids do. The new LiFePO4 batteries have a much better lifespan and are nearly the same price these days.
The link has references that apply to both battery types.
The 12v to 5 volt USB adapter linked likely isn’t available anymore, but there are plenty of others available.
I may need to add 1 or 2 more panels though as I have 2 wyze cams and a Reolink PTZ, plus at night a 20W IR floodlight that lights up everything.
Daytime power draw is 1.2 Amps per hour and nighttime draw is 2.5 Amps per hour. The IR flood light draws more than the 3 cameras.
Renogy mini cores series batteries are high in quality and are the closest you will find in build quality to a Battleborn LiFePO4 battery. Battle born is the quality leader of those batteries in the U.S.
The Renogy batteries are much more affordable 
So after much review I went with Renogy batteries in several battery backed power systems for my needs
For outdoor use where it freezes I used a self-heating version of the battery.
Waited for it to be on sale though at $239
The Solar Charge controller needed update to configuration for LiFePO4 battery type.
As seen in the counters I used 1/3 of the batteries capacity at night and at nearly noon I just started charging. Tall trees and shading are Not a Solar systems friend
