Car Sunshade Board Solar Powered Panel Auto Car Battery Charger with Suction Cups

Pros: The panel does what it promises. I haven’t checked the actual current, but I use it to extend the life of a battery powered electric fence. On a sunny day, I can disconnect the battery, and the solar panel is able to power the electric fence transformer (This is of cause a pulse load, but the average energy delivery seems to be suficcient.) It sits outside in rain and wind, and it is not harmed in any way. It also comes with a variety of cables and connectors, and even a USB-charger, so you can charge a USB device directly from the panel!

Cons: Quite small. It would be nice if it was twice the area – it doesn’t even fill out half a window in a car… But then you can just but two.

Other: Easy, useful and ok priced.

Pros: I bought two pcs and connected paralelly together through diodes. So I have in load 14 V but 16 W. Together with 10 A regulator is connected to car battery. Auto battery is charged every day when is sunny but little also when is cloudy. I have always fresh battery and starting is no more problem. More watts = more strong battery and best conditions for starting car. Be aware and use proper connections and fuses. Panels are mounted on front window (always) i must not do anything, charging is automated and in night the charger will stop and automatically disconnect battery.

Cons: I have not any problems.

Other: :-)
