so far so good, charging for car trailer

Excellent for maintaining charged my electric plant battery

Perhaps it sucked the charge out of my battery and used to to fuel the sun

Even sitting in the winter weather , through that big storm, kept the battery nice and fresh all with no extra charge $$ wise but the cost to buy..

I put this solar panel into service on my sailboat and it has kept my battery well charged so

Now the control unit has apparently failed and the charging LED only flickers occasionally

Had this tender for 6 months and holds a charge well on my deep cycle

I specifically use this charge to top off and maintain my RV batteries

great charging results

I have used the Battery Tender that plugs into a 110 volt outlet on these same batteries and they are fully charged in 12-36 hours.

I was propping the panel against the inside of the windshield of my parked car where it could receive direct sunlight in the afternoon, but even when the sunlight was indirect, the LED charging indicator on the Battery Tender would glow as soon as the sun was fully up in the morning

I love it so far it's charging my tractor to riding lawn mowers and a deep-cycle boat battery

Not good for vehicles.. had very little charge when using this

My tractor battery is super charged up about this product!

It's been sitting idle/charging for almost 3 months and it's still not showing the green light stating that the battery is fully charged.

Works as it supposed to.

Sometimes seems to work ok sometimes, but it's really hit or miss as to whether the battery is actually charged when the light on the charger says it's charged.

Has worked as I had hoped so far, I will update my review if I have any issues
