  • Well-working robust and versatile

    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!

    Easy, useful and ok priced.
  • It works well and description appears accurate.

    Useful size and form factor. Provided suction cups help in attaching the panel to windows inside the car, or on the inside of the window of the house (as how I had used it). I leave mine permanently attached to a used 12V car battery (without a solar charge controller) and it always keep it well-charged without overcharging it.
    I suspect this panel does not have a built-in blocking diode that prevents the panel from drawing power from the battery when the sun goes down, but I can't verify that as it doesn't bother me too much.
    Useful and decent quality panel, albeit a little bit expensive.
