Product Description
The Sunforce 50022 5 Watt Solar Battery Trickle Charger gives you
another reason to love the sun -- it'll help keep your vehicle's
battery charged. Just plug the this helpful 5-watt trickle charger into
your vehicle's 12-volt lighter socket and position the panel to pick up
the most daylight possible. Or, if you prefer, use the included
alligator clips to connect it directly to the battery, so you can keep
your lighter socket open for cell phone chargers or other accessories.
Regardless of how you hook up the battery charger, you'll never get
caught off guard without the juice you need to start your car. You can
also use this device to maintain the charge on any 12-volt battery for
clean, silent operation of various electronics, such as deer feeders
and landscaping pumps. The 50022 features a built-in ultra-bright blue
LED charging indicator, and is a great choice for automobiles,
recreational vehicles (RV), tractors, all terrain vehicles (ATV),
boats, electric fences, telemetry and more, and it is even effective on
cloudy days. This trickle charger is made of durable ABS plastic and
amorphous solar cells, measures 14 x 0.75 x 13 inches (WxHxD), weighs 4
pounds, and has a maximum temperature range of -40 to 176-degrees
Fahrenheit.

Convenient Power That Helps Keep Your Batteries Charged
The Sunforce 50022 5-Watt Solar Battery Trickle Charger lets you
harness the power of the sun, the most powerful and plentiful source of
energy available to us. Unlike nuclear and fossil fuels, solar power is
clean and pollution-free, and the equipment requires very little
maintenance to operate.
This trickle charger is designed to
stave off the natural voltage drain that 12-Volt batteries undergo over
time. It can also maintain the charge of a 12-Volt battery while it is
providing energy to small electronics like cell phone chargers or small
pumps and motors. The Sunforce 50022 5-Watt Solar Battery Trickle
Charger is constructed with durable ABS plastic and features amorphous
solar cells and an ultra-bright blue LED charging indicator. Four
mounting holes are pre-cut in the frame for easy permanent
installation. It is weatherproof and remains effective even on cloudy
days. The built-in overcharge/discharge protection prevents
overcharging and reverse-current drain. This trickle charger is an
ideal choice for automobiles, recreational vehicles, all-terrain
vehicles, tractors, boats and more.
Sunforce Solar Panels are effective in areas of both high and lower
sun exposure, making them ideal for use in the United States.

About Amorphous Solar Power
Amorphous solar panels are created by spraying silicon on to glass in
very thin layers, and are commonly known as thin film solar panels.
This process allows them to be better at generating electricity in all
lighting conditions, including cloudy or shady environments. Sunforce
amorphous solar panels are weatherproof and suitable for outdoor use.
They have a maximum operating temperature range of -40 to 176-degrees
Fahrenheit, require virtually no maintenance, and are also effective on
cloudy days.
Solar cells convert sunlight into an electric
current; they do not actually store power. The Sunforce 50022 5-Watt
Solar Battery Trickle Charger is designed to maintain an existing
battery charge, and not to fully recharge a battery. It can remain
connected to a vehicle battery at all times and will not adversely
affect its operation or electrical components. Unless the trickle
charger is permanently mounted, you should remove and store it to
prevent physical harm while the vehicle is in motion.
Customer Reviews
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.
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.
Panel stopped producing electricity in November. Had to send it in
to Sunforce at my expense for warrantee replacement. They promptly
tested it and sent me a replacement. One thing I did notice is that the
plastic housing on the unit that I returned had developed some small
cracks. I am using the unit on my car dashboard to keep my battery
charged.
An Overperformer!
This unit has consistently performed _better_ than it is rated for.
It routinely generates over 140% the rated voltage - and even generates
the Rated Voltage on overcast days. A *streetlight* at night caused it
to generate a measurable voltage (~50% rated, as I recall). Also, it is
weather/hailstone resistant. I am very pleased with the performance of
this item.
