The performance of this panel is very good, and I am very satisfied. Under good sunlight conditions, I tested that its wattage can reach 89W. If the sun were stronger, it should be able to achieve even more wattage, and I am very satisfied. Lightweight and easy to install, the panel has 6 mounting holes on the edge, which can be hung on the wall or glued together. Very convenient, I plan to buy 6 more for my RV.

I needed an extension cable to connect some portable solar panels to my RV. This set of cable worked out just perfect.
Pros:
1. The cable has a fabric cover that keeps the red and black cables together.
2. The cable cover keeps the cables from tangling into a mess.
3. They are weather and waterproof.
4. The 20 ft length will allow you to set your solar panels away from obstacles.
5. They are made of good quality material.
Cons:
1. When they not in use they take up storage space.

Muy buen producto

Quality construction...
but, buyer BEWARE!!

The polarity on the output connectors was reversed from the factory...black to red and red to black.

Once corrected the panels function as promised.

Check the specs on your battery pack or device(s) you are powering and all cabling to assure wiring polarity is correct.

So far so good!.
