  • 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.
  • 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!

    For what it does, you cant really beat the price. Does what it should, out of the box. I plan on buying more of these actually in the near future!
    I have a spare 550CCA batter in my garage which im using to charge(Of course itl take some time as its a big battery.
    This unit is GREAT for what it does. You just have to be a little gentle with handing it, which is fine. Not bagging the product - I would actually buy MORE of these!
    20V+ on a sunny autum day here in NZ, cant go wrong mate. Good job
    Does what it should, nice and simple.
  • good product, but pay attention

    Small, with matte finish that helps to catch more solar energy.
    If you want to use it for small things (leds, small electronics) I think it would be ok, but pay attention to electronic device that absorb more energy.
    For the price, I think is a very good product. Very easy to use and mount. I think you’ll need also a voltage regulator to use it at his best.
  • Great product, NOT for Iphone 4

    Built great and sturdy.

    Its a handy product. There is no point getting anything above 5W anyway as most mobile devices can only accept up to 5W of power. I live in the tropics so getting sunlight is not a problem. Well made
