solar battery charger Customers Reviews

  • 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.
  • Nice thing for my diesel car battery

    posted by matolegin2

    I bought two pcs and connected paralelly together through diodes. So I have in load 14 V but 16 W. Together with 10 A regulator is connected to car battery. Auto battery is charged every day when is sunny but little also when is cloudy. I have always fresh battery and starting is no more problem. More watts = more strong battery and best conditions for starting car. Be aware and use proper connections and fuses. Panels are mounted on front window (always) i must not do anything, charging is automated and in night the charger will stop and automatically disconnect battery.

  • Good staff

    posted by umutkose

    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.
  • Excellent Device for Car Battery maintenance

    posted by GarryJSmith

    Excellent device for keeping a car battery topped up.I have this mounted on a visor and running directly to the battery using the cables provided. I can now leave the alarm on for several days without running the car and the battery is always topped up when I use the car.Purchased another already and my brother is using it to keep his boat battery topped up and it is doing that task perfectly.
    I can think of many uses for this device - can be applied to just about any 12 volt devise to keep batteries charged and possibly even run the devices.
    Worth the dollars and the wait to get them - would buy more without hesitation if needed.
