Since COVID-19 arrived, many people aren’t driving as far or as frequently as they used to. The lack of vehicle use can lead to car batteries that aren’t sufficiently charged, which in turn can lead to shortened battery life and/or a dead battery. One solution is a 10-watt solar trickle charger from Eco-Worthy. The 1.5-pound unit attaches with suction cups to the inside of the windshield or the rear window. It can be plugged into a 12-volt socket or attached to the battery terminals using the supplied spring clamps. Eco-Worthy states the unit will generate power in temperatures from -40F to 175F.
