Installed Gnet G-ON2 dash cam with parking mode. It works great the video show Battery Saver Plus kicking in when the voltage got low and charged it back up. Might have to full screen video to see voltage at 12.2 then green light starts flashing up to 15v. Dash cam has auto shut off if battery gets to 12v luckly Battery saver kicks in just before that. Have had it for a week or to no issues.
