Rated 4 out of 5 by thedogmax 12 volt solar charger
Works well even on clouded days. Volt meter shoes 18 volts on full sun about 13.5 on low light.Battery clips are not worth a hoot,replaced them with good clips, so far the charger keeps the battery at full charge and i dont have to run electric cord to it,just hook up the battery clips and leave it alone. I used a piece of velcro to hold the charger in place

Rated 5 out of 5 by APR3245 Does what it is supposed to do
This panel doesn't put out a whole lot of current. It isn't desgned to. For a large capacity battery it is more of a maintainer than a charger. My truck battery was getting a little long in the tooth. Leave it sit for a few days and tthe security system draws down the batt and no start... Took a week long trip out in the bush. Plugged this unit into a constantly hot power outlet, tossed it on the dash, came back a week latter, and it had done its job perfectly, keeping the batt topped off. For those giving low marks for performance, LOOK AT THE SPECS! It ain't designed to recharge your deep cycles after a day of fishing or even while fishing.

Rated 4 out of 5 by Lostagain Maintains charge well
I'm using this to maintain the charge on my spare battery. It works well to maintain the charge, but don't expect it to charge a discharged battery.
One quibble - the red LED indicator is pretty bright and stays on as long as the charger is connected to the battery. That's not a problem in daylight, but at night I'm afraid it might attract unwanted attention - some people tend to be attracted to bright, shiny, unguarded objects. It would be nice if the light could be turned off, but I guess I'll just have to keep it covered with electrical tape.

Rated 5 out of 5 by sportsman2 well worth the money.
I have had my boat out about 4 times since I bought the solar charger and my battery is always at full charge.

I'm looking at attaching this to a garage where my boat sits for 9 months out of the year, but the roof is 20 feet high. I would need about 30 feet I'm guessing. Is extending the cable length possible?
The wire that comes connected to it appears to be about a 18 gauge wire. If you were to add 25' to 30' of 14 gauge wire by using very tightly installed wire nuts or, in my opinion, soldering this wire extension & insulating the joints, I don't think you'd have any problems. I would be more concerned about debris covering or breaking this panel.
The short answer is: you're probably just fine. There is inherent voltage drop that will happen, but the amount of loss will be negligible. I would be more concerned with ensuring you don't go on vacation and find a burned down boat and/or garage. Use a good Deutsch style connector and make sure everything is weatherproofed.
IF YOU MEAN TWO CHARGERS FOR TWO BATTERIES ,WHY NOT.OR EVEN TWO UNITS FOR ONE BATTERY AS LONG AS YOU ARE NOT EXCEEDING THE VOLTAGE LIMITS AND JUST GIVING IT A HARDER CHARGE LIKE A PLUG IN CHARGER WOULD DO FOR 2AMPS/10AMPS.(slow or fast)
I lost the instructions that came with the unit. I remember briefly something about it being properly connected if the light is green and not connected/ problems if its red. But I'm pretty sure I connected it fine, and it's still red. Does this mean that it's still charging, or that there is something wrong with the unit?
