solar panel charger Customers Reviews

  • 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.
  • 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.
  • Good staff

    It has a compact case. you can put all staff together. case seems very durable. material quality is very well. output seems stable under direct sunlight. i got 550 ma current on short circuit for 30 seconds. there is also a output control circuit on it. if you dont have direct sunlight it cuts off power. its good for general use.
    if you plan to use an automatic step up/step down circuit you should disable circuit on it. because panels generate some power under daylight (not direct sunlight) but output circuit blocks it.
    you can use it at everywere. but think twice at outdoor. it isnt waterproof.
