### ⭐⭐⭐⭐⭐ It works
*by O***O on January 1, 2026*

Working like a charm. Keeps my battery charged

### ⭐⭐⭐⭐⭐ Excellent
*by R***T on May 28, 2025*

I picked this Solar Charger up during Amazon's Memorial Day sale and so far it works as described. As anyone knows, a project vehicle can take a long time to complete but knowing my battery remains charged and ready to go when I finally fire up my project gives me peace of mind. Having a good battery is now one less thing I have to worry about!

### ⭐⭐⭐⭐ Works great...watch your polarity
*by R***. on July 21, 2019*

First solar panel I received was cracked (hence the "4" rating); however, the second panel arrived intact. I use the solar battery charger to keep my Harley battery charged within an enclosed trailer. I connected the charger to my battery via use of a Schumacher EC-25 25' Cable Connector Extension Cord (through a connector I mounted on the side of the trailer housing) and Schumacher WM-12 12" Cable Connector for Battery Charger/Maintainer. If you use the Schumacher battery connection harnesses and just plug everything in "as is", polarity will be reversed at the battery and the battery charger circuitry will cut-out (electrically isolates from the battery)...the blue LED on the charger will not illuminate when it's connected to the battery (since polarity is reversed). Once I used a multimeter to identify and correct the reversed polarity, the blue LED on the solar panel illuminated and the battery charger now keeps my battery fully charged. Several people have commented on the reverse polarity issue...add me to the list! I also connected a voltage regulator/charger controller between the solar panel and my battery because the solar charger output varies so dramatically (0 volts to 24+ volts under full sunlight conditions). I wasn't comfortable with "double voltage" reaching my battery, although I've read the controller isn't required for such a low wattage solar charging system (I opted for overkill for my own peace of mind). I also didn't trust the suction cup mounts to secure the solar panel to the side of my trailer...I installed bolts/wingnuts for the top mounts and let the bottom of the panel rest on 2 suction cups (since they don't bear any weight/load). It's still very easy to remove from the trailer for road trips.
