Sollight.com has released details on the new SoliCharger accessory for the iPhone 3G, 3GS and 4. This $60 device has a 1600mAh battery which can be charged via USB, a 110v Apple charger, a 12v Apple car charger, or for free via direct sunlight. If you plug it in to charge at home, it will take about 1.5 hours to fully charge, and that will in turn fully charge your iPhone. The device also has an adapter kit which allows you to use the battery to charge an assortment of other devices like GPS, mp3 players, and more. Charging the device in the sun takes a bit longer however. The solar cells are producing about 100mA and will take about 8 hours to charge enough to get pep back in the iPhone’s step, or about 20 hours of exposure to the sun to fully charge the 1600mAh battery. So if you’re outdoors a lot, or simply want a flexible charging alternative, this seems to be a good choice for the time being. Hopefully the solar cells will produce more power in the coming years.
