I bought one from Maplin some years ago. It generated enough output to
light up the LED on it, but no more. It was sold as a 12V car battery
charger.
Probably the same as the one I have, 5" wide 14" ish long?
It might have been useful to counteract self-discharge of a stored
battery, but no more.
In full sun it probably will charge a bit but really all they are is
self discharge eliminators. The LED on mine flashes, when it's on
there is very little on the output, the mark/space is around 1:1 so
50% of the very little produced is wasted... I must rescue it from
the garage and "get at it". B-)
