Solar power 12 v battery charger

Bought this solar panel battery charger to replace one that went bad. I am using it on my lawn tractor, has been in use for about 3 weeks and no problems. The other unit lasted a few years so for the price it's a deal! Better than using an electric charger in an outdoor situation. I am using another one like this at my sisters house for her zero turn unit. It has been in service for about two years with no issues!

Appears to be working well so far. My truck had been sitting idle for a couple months and battery was draining, So far it appears to be getting stronger, but haven't finished repairs, to be able to start engine. By the way, I cannot read the markings on the fuse in the cigarette lighter connector. what would be the correct fuse if I need to replace it?

Works Great!

I like the fact that this device works. I tried it (alligator clip method) on three vehicles for one afternoon (winter). Each vehicle got about 45 minutes ( /-). I verified that each battery had a slightly higher voltage after charging than before (Agilent multimeter). I did not try the suction cups. I did not try the cigarette lighter plug. So far this is well worth the small price that it cost me. I don't like the fact that this device came without any instructions. There was no paper with precautions. I think there should be something of that description. Maybe I should just be happy with a working device and use some attention to detail to avoid damage to my vehicles.
