SOLAR BATTERY CHARGER
Yet another reason to love the sun: it'll keep your car's battery charged. Just plug this helpful 15-watt solar charger into your vehicle's 12V lighter socket and position the panel to pick up the most daylight possible. The powerful 15 watts means you can use it for boats or larger vehicles too. You can also charge batteries to run lights, TVs, VCRs or other small appliances. Blue LED light shows it's working. Works on cloudy days too. A 7-amp charge controller is recommended (sold separately). Imported. 2-1/2Hx15-1/2Wx41-1/2L".
Customer review:
Works as advertised
It arrived quickly and in perfect condition. It produced the rated open circuit voltage and short circuit current in full sunshine per the specifications. It was a good buy, very good for maintaining a battery, but you must use a charge controller. You need several along with a charge controller if you intend to produce enough power for useful work. I use 5 (similar) together with a 100 amp/hour marine battery to power my laptop. I'd like to add a few more! Great for the hobbyist who wants to play with solar without a large expense, also useful for low power off grid applications. It has been outside during several large rainstorms and had no problems.
