Product Description

The Sunforce 50012 1.8-Watt Solar Battery Maintainer gives you another reason to love the sun--it can help keep your vehicle's battery charged. It provides up to 1.8-Watts or 125mA of power to prevent the natural voltage drain of batteries over time. It includes both a lighter socket adapter and alligator clips to give you flexible connection options.

The Sunforce 1.8-Watt Solar Battery Maintainer is compact and easy to install.

Convenient Power That Helps Keep Your Batteries Charged
The Sunforce 50012 1.8-Watt Solar Battery Maintainer 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 battery maintainer 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. The Sunforce 50012 1.8-Watt Solar Battery Maintainer is constructed with durable ABS plastic and features amorphous solar cells. This unit also includes suction cups for easy in-car installation. Since it is designed for use inside of a vehicle, it is not weatherproof and should be kept dry. This battery maintainer is an ideal choice for automobiles, recreational vehicles, 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. 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 50012 1.8-Watt Solar Battery Maintainer 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 battery maintainer is permanently mounted, you should remove and store it to prevent physical harm while the vehicle is in motion.

Sunforce 1.8 watt solar battery charger

Review Date: October 10, 2007

Reviewer: Paul D. von Fischer,

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!!!

Best battery maintainer set with affordable price

Review Date: February 1, 2009

Reviewer: eastcoaster, USA

Pros: Affordable price, good choice of connectors and clamps, compact design, long cable length, blue led indicator helps determine activity, very good shock proof packing, simple easy to understand instruction manual, light weight, environment friendly and saves electricity money.

The price of this item is reasonable and affordable. Perfect battery maintainer for the long winter months. Panels comes with its own clamps, adapters and connectors. Just to make sure, I checked the battery voltage before using this item and after using the item and the maintainer surely works great. The batteries show no sign of drainage or loss of voltage since one month. I have seen the voltage has gone up slightly indicating a good charge everyday.

Cons: One panel-wire had a loose connection (soldering). The LED light indicator turned ON sometimes and if I moved the panel-wire it went OFF. I understood it is loose soldering. If I had a solder iron, I could have easily repaired the loose connection. Since I don't, I returned the item and got another set which is fine.

Great little gadget

Nice little battery charger that maintains you battery. The flashing blue led lets you know it working and the cigarette lighter adaptor is a big plus for being easy to use. The only thing I noticed was that the cigarette plug adaptor sometimes pops out of the socket. Not sure why but it appears it's a little long and the center contact sticks out fairly far and the side contact springs don't go in far enough to hold it in place. I have to assume this a little too long and therefore pops out and would become useless to charge the battery then and if you leave it long periods wihtout being able to see if it's still pushed in it would no longer be charging the battery. Other then that is works great. It might be that my cigarette lighter plug is on an older car but would have thought they are a standard size.

I would recommend it 100%

70 mA Trickle Charger

Review Date: September 5, 2009

Reviewer: D. MCDONALD, Washington, DC USA

I bought this array to trickle charge my 12V battery in my '05 Civic (I don't run the engine long enough between startups to maintain battery voltage). Attachment through the factory accessory plug was not feasible--the key must be turned to "accessory" for the plug to work, which then also powers up the radio. [Curiously, if I connected the array to the plug without the key on, I could turn on the radio, implying that the array was powering everything in the car that runs on "accessory"!] I therefore installed an always-on power socket; to do so, I installed a Bussmann BP/HHH ATM Add-A-Fuse to a unused fuse plug in my interior fuse panel, and attached to it a Radio Shack 270-1527 socket (after clipping off the battery clips).

In full sun, the array produces 70mA of current at 24V (60mA when properly attached to the battery). When attached in reverse, the array LED and diode together draw microamps of current (my ammeter could not measure that low of current).
