Newpowa5W(Watts) 12V(Volts) 5W Monocrystalline Solar Panel Battery Maintainer High-Efficiency PV Module Power for Battery Charging of Boat RV Gate Opener Fences

light weight. Had to modify for mounting; however, adding a couple of new bolt holes was no big deal. Works like a charm.

It's just like the bigger panels, but mini sized. Rated to .67A in clear skies, but I haven't measured. It charges a small 12V battery just fine for me.

I wish the manufacturer included mounting hardware but the actual solar panel is excellent. It delivers the rated wattage and works nicely even under cloudy conditions to keep my DIY 18650 based 12v Li-Ion Battery pack topped off on a daily basis. I am running Aquarium pump 24hrs a day using this DIY solution.Oh by the way, I did use a  Renogy Wanderer 10 Amp Solar charge controller  to safeguard against overcharging of the Li-Ion battery pack on very bright sunny days. Having said that, Just like other reviewers who has commented, I too had some difficulty in mounting this on a roof. I had to improvise and got some additional mounting hardware from local store and drilled additional holes to mount this on roof.If you are handy and do not mind finding your own mounting brackets then for the asking price the solar panel is surely worthy of the price.Rating the product with four stars!

It has been working with my battery tender for over a year now, no issues.

i have bought 2 of these, at separate times. I bought the first one to charge a 6ah 12v battery in my shed to power some 12v fans on a temperature circuit to keep it ventilated in the heat. I just bought a 2nd one as a upgrade to add extra power for some more fans, and fitted to the solar controller i bought these keep both batteries fully charged even when fans are running all day, even on days where the weather isn't ideal. My only gripe is how hard to mount they are. The screw holes are to hard to get to, so i ended up bounding them to the shed roof. I guess they are made to fit a rack, and i was unable to find one that worked. Well worth the money, but must be fitted with controller because peak unloaded power is 22v, (normal for a solar panel incase you didn't know) so it would kill a 12 volt battery without one.

Well made.

Works great at maintaining a rarely used vehicle of mine. When it keeps it topped off on voltage, I get away with leaving the battery in the vehicle in cold Wisconsin winters, and it never dies out. Remember to have a charge controller, so as to not over charge the battery. Stop reading reviews and just get this done before winter. It will be your friend and take care of you.

Easy to connect and provides enough power to keep a gate charged.

I recomend this product .
