The device received did not match the declared one.

Listing is 9.44" x 13.8" 10W solar panel. The panel measures 9.25" X 7.3" so it's most likely only a 5W panel. In this case, it's a bug, or maybe a bait-and-switch situation. In any case, keep this in mind. The instructions provided are confusing and do not make clear the proper setup. An explanation available online would be very welcome. I couldn't find one.

Pros
  • Cool product
Cons
  • Something different

Solar Panel Solar Charger

Ultimately I couldn't get the unit to work. The charger didn't work from the start. I connected the solar panel to my car but when I tried to activate the charger it didn't work. I couldn't activate any of the options. I'm pretty mechanical and can usually figure things out, but there were no instructions on how to get started. I really don't think I would recommend this product to a friend unless they have a degree in physics or mechanical engineering.

Pros
  • Great Price
Cons
  • Big and Chunky

Non waterproof solar panel?

The charge controller I received worked fine except for the load switch. Regardless of setting 0H for "dusk to dawn" or 1H-23H for timed lighting after sunset, none of them worked. I contacted the seller and they had no idea what I was talking about and said it wasn't a feature even though the manual correctly states it. Besides, who sells a solar panel that can only be used on sunny days? That's right folks, this solar panel is not waterproof or even waterproof. It's fodder for our stable, so…

Pros
  • Easy installation
Cons
  • There are other interesting options.

Doesn't charge my phone well.

I attached a panel with suction cups to a second floor east-facing window that gets half a day of direct sun. Connecting my Galaxy Note 8 phone directly to the panel. The phone shows that it's charging, but the speed is so slow that over time my phone's overall charge is decreasing rather than increasing. I wasn't expecting much from a panel of this size, but I'm not sure I can really justify it when it can't even charge a phone efficiently enough. I just ordered a 25w panel to replace this…

Pros
  • Sturdy construction
Cons
  • No automatic controls
