This solar car battery booster replenishes the power that is naturally lost by your battery during periods of inactivity. It trickle charges your battery and keeps your battery fully topped off.

Using this solar booster can, in fact, prolong the life of your car battery. The trickle charging process charges up your battery by preventing deep discharge cycles that occur in dormant batteries. This process essentially extends the life cycle of your battery.

Simply plug it into the cigarette lighter outlet in your car, and your car battery will be kept fully charged whenever the panel is exposed to sunlight.
