Weighing just half a kilo and measuring 45cm by 15cm by 2cm, this 12 volt, 1.5 watt solar trickle charger provides longer battery life for infrequently used boats and vehicles. It comes with 2.7 metres of cable and a simple connection via either a 12V cigarette plug or battery clips. Flashing blue LED denotes charging while in-built blocking diode protects against reverse discharge. Amorphous solar cells use the sun's power to maintain the battery in peak condition, even in low light (cloudy) conditions.
