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 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.
Solar panels convert sunlight into an electric current, they do not store power. Amorphous solar panels are created by spraying silicon onto 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, requiring virtually no maintenance. They can even withstand impacts from one-inch hailstones at 50 miles per hour.
Amorphous solar cells work in all daylight conditions--even on cloudy days. Please note that this amorphous solar panel needs to be inside the dash of a vehicle or by a window indoors as it is not waterproof.
Amorphous Silicon key points:
It does what is says, and you can make the unit weatherproof per the enclosed instructions with some silicone. Read morePublished 3 days ago by Ghostt

Works for what they say it will. I use 2, 1 in a truck that sets a lot, and another to solar charge a battery I use to run lights in my shed.Published 2 months ago by Amazon Customer
