   Decent little solar panel with nice options
   Setting on dash of work truck we use once and a while. Typically we go to use it and battery has drained. No short can be found, so we thought we would try this. Will update once we see how it works. Panel seems to be built well and looks like it will hold up. Did not use suction cups that came with unit. That is why i did not rate them.

   Works. But polarity is switched
   The wire to power from panel is reversed. I compared it to a standard plug I have for my other chargers. I will fix it by cutting and splicing. I fixed it temporarily using alligator jumper wire.

   Failed badly after few monhs
   Worked perfectly for a few months, but then it caused a complete battery discharge (battery tested after recharging with good charger and it is fine).

   Good output for the size
   Very good out put for 7”x8” almost the same wattage as my 12”x12” panel, I have it on the dash of my diesel truck and it works so well than if it lasts for a year I will buy a few for my tractors. Big problem I have buying batteries.
