This solar charger was the perfect solution for battery draining during a pandemic. Between infrequent short drives and phantom discharges from alarms and other systems, my fairly new battery kept failing me. After connecting this charger to my OBDII socket, the problem is solved! The cigarette lighter/socket was not present in my vehicle so be sure to check. The panel is thin enough that I can slide it between the sunroof and sunshade panel, giving it good coverage for most of the day and easy to remove + no fiddling with the included suction cups. My only complaint is that the charge indicator diode is hard to see on a bright day.
