When you need a tougher cable to go between your portable solar panel & your storage battery. 5.5×2.1mm barrel connector at one end (battery), and standard DC CLA connector at the other end (solar). 8′ length, and 18 gauge wire. LED power indicator.
Recommended for use between Powerfilm solar panels and Brunton solar storage batteries. Replaces the small CLA cable provided with the Brunton batteries due to a voltage drop in that cable that prevents a full charge from Powerfilm panels.
