Can I just lop off the cigarette lighter plug and connect the ends to one of those AA battery adapters from Radioshack
It will work.A pretty inefficient way of doing it , but as long as the AA batteries you are charging are more than 2000 mah capacity it will charge them, albeit very slowly.
Its a very inefficient way to charge AA batteries.
QuoteIts a very inefficient way to charge AA batteries.By "inefficient" you mean that there energy is lost somewhere, or it's just a slow?
Although the Solar Panel is rated at 1.5 watts, the most it can deliver is 100 ma .Into a AA battery, either nimh or nicad , thats only 140 milliwatts.
Given that most places on Earth have less than 12 hours of sunlight during the majority of the year, that's about three days total.
If the device powered by the said batteries draws only 30mA, for example, in a few days, the batteries will become fully charged, but the solar panel will still provide 100mA. Aren't they going to become overcharged and heat up?
My point was that there can be a situation when the batteries are fully charged, but the solar still pumps more current into them. What's going to happen then?
