The 9 Best Solar Panel Cigarette lighter Battery chargers (2023 reviews)

If you often find yourself confused about good charger, sunway solar solar panel cigarette lighter battery charger is your solution. If you throw in a few cloudy days, less than ideal tilt angle, and some parasitic draw from your vehicle, a 5W panel would give you a safe margin. It just maintains a 12v battery. You can hook it directly to the battery using the (included) clips or you can install a cigarette lighter port directly to the battery. After the attempt it is down to 11.5v, clearly no good. It is an edit to ask Amazon a question. If there is a circuit to prevent charging from the lighter socket, it would not work.

You will need to purchase a voltage regulator, like https. It can not charge your cell phone directly.
