Perfect for my campsite
I live on a river and built a campsite on an island across from my house (the dog loves it). I bought a deep-cycle marine battery but am getting too old to lug it in and out of the canoe for charging. So I got this little panel and, so far, have not run out of juice. And it's cheap enough so if someone steals it it's no big tragedy. I run a laptop, TV, fluorescent light and charge my cell phone. I even have a 12v car-vac to clean the sand out of the tent.Of course, I'm not there 95% of the time so 5 watts is probably adequate. And I don't have to worry about overcharging. I screwed it to a big log in pretty open sun. So far, it has survived, even some small hail.BTW, I use the power cord from an old vacuum cleaner and a 4-way 12v splitter to distribute power from the battery.
A nice tool for those who take long trips away
In 2006 I took a 3 week vacation out of the country. I left my car at the airport and away I went. Upon my return, I had to have the battery boosted for 15 minutes before it would turn my car's engine on. I have no idea what caused the drain (Sattelite Radio memory, car's other computers, etc), but I had to do something to prevent a $50.00 boost call in the future. A coworker told me about these devices and how his brother uses them to keep his mobile home powered when parked. Higher wattage products are sold, but if all you're doing is keeping a car battery charged, 5 watts is plenty of power for the job. No other devices (charger controllers) are needed. The charger comes with a couple of ways to hook up to the battery (direct battery terminal clips, cigarette lighter plug). I used the cigarette plug. Just plug it in to the power port, and lay the solar energy collector side face up on your dashboard. For those with heavily tinted windshields, I have no idea if the tint would cause...

Good electric output but fragile / bad packaging
I recently ordered one of these panels (June 2007). The first one arrived shattered - the manufacturer packaging does not protect the panel much and it was inadequately packaged in the shipping box by Amazon. The replacement unit was also badly packaged for shipment.I tested the electrical output in full sunlight and got 20V out into a 100 ohm load -> 4 watts which is pretty good.One thing to consider though is that this product is not very rugged. The solar panel has a plastic frame but the middle is unprotected on the back (and front). So unless you handle it very carefully it is likely to break.Someone using this on a car dashboard would need some sort of protective carrier (like those insulated pizza boxes) to protect the unit when it was not being used.------------ Update Dec 2007 ----------------Panel stopped producing electricity in November. Had to send it in to Sunforce at my expense for warrantee replacement. They...

I put them on top of my trailer
I purchased these solar trickle chargers all winter. I park my trailer at the storage facility for the winter. My batteries always drain down to nothing. I got these so try and see if I could keep my batteries from draining down to nothing. I built a small little angled mount for them using wood so I could remove it when I was not using them. I put the unit on the roof and made sure my batteries were fully changed first. I left the solar panels on the top of the trailer. I checked the trailer twice a month I checked the trailer and the batteies stayed charged up all winter. Good little units. Will not charge your battey it will maintain a charge.

Electrifying!
These things rock! I bought a pack and connected them to my ATVs and now they are always ready to go! One thing to take note of, though, is be careful not to switch the polarity if you use an extension cable!! I can say that from experience... Batteries aren't cheap either.

These panels worked great. I had a small window and these fit perfectly within. Gives a good charge of 22.5v each. Maintaining a deep cycle battery this worked great.

Sunforce 7 amp Solar Controller
Bad:Really cheap quality. Included instructions don't provide enough information. Website is just as un-informative. Cheap connector wires (low current), and is not equipped with screw-on terminal junctions.Good: Product works as advertised. Amazinlgly "regulates" the voltage to the required amount so as not to overcharge the battery. Beware though, in order to test the actual output voltage, you must apply a load on the battery end of the controller BEFORE. Failing this, the output can register volts as high as 20 volts !!! Apparently applying an actual load causes the controller to output the correct voltage range - lucky me, cause I bought 4 units ! The LEDS alternately flickers (fast for good voltage input and slow for low to no voltage on solar panel). The manual did NOT state the order of LED flashes.(1) Fast LED flashes - good voltage/current(2) Slow LED flashes - low/no voltage/current(3) steady Green - fully charged(4) steady amber -...
Easy to use Charge Controller
Two wires to the battery and two wires to the solar panel. It doesn't get much simplier than that. Worked flawlessly out of the box. Yellow LED indicates charging while green LED indicates the battery is charged.
Charger
I have this unit connect to two automotive 12V batteries with three 15W panels connect to it. So far the charger works as advertised by preventing battery drain when the sun goes down and charging while the panels are producing at least 13 volts. It is pretty much an install and forget item. Additionally I have those same two batteries tied into one of my trucks 12V power points so that the batteries charge when the vehicle is running by way of the alternator. Even with this double charging set up, the charge controller appears unphased and shows a charge light in the daytime and has on two occasions indicated a fully charged green light.

Works, but be careful.
Product works well but you need to check the output at the end of the cigarette lighter plug with voltmeter. I couldn't figure out why there was no power at the cig plug. After some investigating I realized there was a fuse inside the cig plug that was blown. Even though the blue light is flashing you'll still have no power at the plug. I slid the chrome ring off the plug and it opened up exposing a blown fuse. Hope this helps.

Sunforce Solar Battery Maintainer
I installed this battery maintainer on the dashboard of my motor home and plugged it into the cigarette lighter while the motor home was in long term storage. Since the rig faces the morning sun, the maintainer did an excellent job of keeping the battery up to charge. I am well pleased with this Sunforce Solar battery Maintainer and would recommend it to anyone in need of such a unit.

Sunforce 1.8 watt solar battery charger
I purchased this solar charger for a camping trip I had planned. Out in the high deserts of Arizona, I wanting protection that my truck battery will be charged. I have a 1993 Nissan Pathfinder with a WalMart battery. We did use the truck battery too much while camping and that next morning the battery would not turn over the truck motor. Hooked up the Sunforce 1.8W solar charger and by day end the truck started right up. LIFE SAVER!!! I would recomend the product HIGHLY!!!
