    Still working after 4 years!
    Tom Fell (Black Mountain, NC) 9/3/2013 3:40 PM
    This little combination was my intro to solar power over 4 years ago. While I have moved on to bigger charge controllers and batteries, this unit is still in daily use operating an LED porch light for about 5-6 hours a night (every night). I use it along with a 20 watt solar panel and I couldn't be happier with it's performance.
