Review on Renogy Solar Battery Maintainer Trickle by Ines Jones

Works well; keeps the battery level up when I'm using accessories and driving lightly. I've found that the more coolers I can hold, the more current/amps it will produce. I keep a layer of cardboard between it and the glass/case or raise it above the surface to allow air to circulate to try and keep it cool. Under no circumstances should it be installed INSIDE the glass as this will exceed the maximum operating temperature. easy. This reduces the output power, which will destroy the charger over time! You may also need to get extra cables as the length is not very long; Routing can be interrupted.
