*by G***A on 12 January 2026*

Works as stated. Good value. I use it to trickle feed my motorhome starter battery while it is stored. The cables are a fair length for most; however, I did need to extend mine because I wanted it on the roof of the motorhome where it was in the sun all day and not sitting on the ground. It does come with a handy bracket that can be used as a stable stand, or for mounting somewhere. It also has a controller to make sure it doesn't over-charge. I'll see how it goes for a few months and update the review if need be.
