12V Solar panel/trickle charger 2.4W (Kendal LA9)

12 Volt trickle charger/solar panel delivering up to 2.4W and this is NOT enough for a caravan. With standard 12V cigarette lighter type plug. And with plug/socket near input plug to disconnect the panel. Draws 0.138Amps so it is not powerful. Overall size is 35 x 21cms.
