Used this charger for 2 seasons now and it has kept both my PWC 12 volt batteries fully charged and maintained…in winter I have used suction cups to stick on interior side of south facing window….come spring my batteries are fully charged and ready to go!

Great product works as advertised. I have a Dodge Durango that doesn’t get used to often and every now and then I usually start the car to charge the battery, but somehow forgot over the holidays and it drain down to nothing. So before I charge my battery and the traditional sense in plugging it into an actual car battery charger, I decided to get this solar maintainer and see what it does from an absolutely dead battery. I let a charge for one day, and later that night when I put the key in the ignition I did get a beep and then the battery died again. So after that I let a charge for two days, put the key and I heard the beep because the door was open, and it actually beeped A bunch of more times, but when I tried to actually start the car, of course it didn’t start and I know that shouldn’t happen at all. After that I let it charge for five days, and pretty much the same thing happen when I let it charge for two days. If anyone knows something about this please send a message or add a comment to this, the alligator clips that clip on the positive and negative are very thin metal, I wonder if I cut those off, strip the wires, then wrap the bare wire on the battery terminals if I would get a better connection and that would help or is it just simply the fact that 5 W is nothing compared to an actual car battery?

So honestly, it barely works with just one. You notice it, but it’s not Tremendous! So I actually bought 2, 1 each for two cars. I went ahead and connect both of them together at the same time to one car. I didn’t think anything of it, and didn’t use/ turn on my 02 Durango for two months straight. Needed to move it the other day, when I started it up, BAZINGA WHAM BAM there it goes! She turned on so powerful I couldn’t believe it. It’s like as if I just installed a brand new battery. YES, it’s true. I just bought two more for my other car 😉

Had it on my Seadoo all summer – routinely in the past I had a low charged battery when reaching October but not this year – every start all summer till pulling out of the water in the Fall was strong. Recommend as a trickle charger/maintainer – will not charge from a dead battery. Works as stated.

Works well as a boat battery charger. This is my second one and wish it was a little more durable but for the price it’s still not bad.

This solar panel comes with alligator clips for direct connection to a battery or a plug with a LED pilot light that can be used in a always on power point inside the passenger compartment of a vehicle.
The provided plug for a 12 volt power point can be worse than useless because the LED in the plug is wired in such a way that it will use power from the battery in the dark or any time the light levels are to low for the solar panel to provide power.
The provided alligator clips don’t have this LED power drain problem and this solar panel will do a much better job maintaining a battery if you use them instead of the male plug.
WARNING!
I don’t recommend trying the fix below yourself, these 12 volt plugs can swarm and if you don’t get the springs and wire back together exactly right it will short out and can blow fuses or possibly start a FIRE! in your vehicle.
Instead take the solar panel to a local Radio Shack and have their techs replace the entire male plug with one they sell that has no LED.
I wanted to mount this solar panel on the passenger side sun visor of a small truck and keep it plugged into one of the vehicles always on power points, but when I tried this the solar panel would not maintain the battery. In fact the battery seemed to be worse off with this solar panel plugged into the power point.
I finally traced the problem down to the always on LED in the provided male plug, the long winter nights and regularly heavy cloud cover was allowing the LED to drain more power than the solar panel was providing.
I’m a hobby technician so it was the work of 15 minutes to pull the provided plug off the solar panel disassemble it remove the diode and then reassemble it and test it with a multimeter. .
Once I removed the LED this the solar panel has maintained the small truck’s battery even with long winter nights and several days of heavy cloud cover.
I really like the straps that lets me slide this solar panel on the sunny side of the sun visor and for that I gave the product 3 stars, but the male plug with the direct to battery LED effectively cripples any attempt to use this with a always on power point inside a vehicle.
