Dead Batteries aren't fun. Especially in Winter;

That's why we designed the Sunsei® SE 135 - to maintain the battery of your car or small vehicle. And it's so easy to use. Weighing less than a pound, this portable solar panel is engineered with simplicity in mind. The Sunsei®SE 135 comes with suction cups, so it mounts virtually anywhere and connects with an adapter to the cigarette lighter. Just expose the SE 135 to daylight and it begins storing solar energy while charging your battery. It works cloud or shine, through windshields and windows, while you drive or while you're parked. The epitome of a little powerhouse. We believe in what we say, that's why the Sunsei® SE 135 is backed by a 10 year power warranty.
