  • 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.
  • handy piece of equipment

    output voltage is adjusted by potclean and well built PCBvery stable output voltage. With load or without it was exactly the same 12.15V while input voltage dropped from 4.14V to 3.86 after connecting fan.
    running PC case 12V fan from Li-Ion batteryin = 3.86V x 0.98A = 3.783Wout = 12.15V x 0.24A = 2.916Wefficiency in this particular scenario 77%no loadin = 4.14V / 22.3mA
    it works and does what says on a tin.

    Performed as claimed. Here in the New Zealand (at quite low latitude 38' South), and just coming out of winter I measured up to 6.39V open circuit, and 30mA short circuit.
    Not fully weather-proofed ... you'll need to take care of this if you plan to use it outside. Inside (e.g. against a sunny window) no worries.
    Looks interesting for hobbyist use to maybe power some little 5V (or less) low-current project.
  • Really good

    The fountain is made of a fine quality. I'm actually pleasantly surprised at the quality. It is easy to assemble, there are 3 different nozzles and 2 mulugheder for the height of the spout. The pump is virtually silent. They have a strong long cord from solar panel to the pump. All in all I think it's a bargain.
    All in all, it is a fine quality at a good price.
    Arrived about 2 weeks after ordering.
    Good quality at a great price.
  • Works great!
