Had a problem with my car battery. My husband sent for this. He is a auto mechanic. hooked this up just to be sure that really cold winter weather would not freeze me battery again.

I installed to my car. Cause battery is draining while parking. But this panel is 12W only. Not good enough power for my situation. I nee to buy bigger one.

i try to connect with my surveillance which setting outside at my house. However, it cannot charge at all. I follow the instruction, and try to setting everything good. Another issue might be the waterproof and with strong wind. Will try a bigger solar panel and steady one next time.

I installed it on a trailer that’s barely used. After 2 months I measured around 14V on my battery. It maintains but not strong enough to recharge a dead battery. At this time is winter, the panel is installed on the trailer box vertical, facing South. I tried on top of the box (horizontal), but didn’t work because the sun is too low. The multitude of connectors made it easy to measure the current, to try different locations. Overall is a good value for the money.

Purchased this product to keep the battery charged on my dump trailer when not in use. Used the suction cups that were supplied to attach the solar panel to the top of the trailer tool box.

The suction cup pads are to short. The module on the back is thicker than the suction cups . Doesn’t stock to my fuel tank because of that.
