I’m not talking about the solar panels you see on people’s houses or miniature ones you would use for a single device.  I’m talking about a highly portable, foldable, solar powered battery charger that has dual USB ports that can simultaneously charge two devices including iPhones, iPads, Android smart phones, tablet computers, all Kindle devices, digital cameras and other USB compatible mobile devices.  Plus, it has a 12V DC output port with a 10-ft cord to charge 12 volt batteries.

Unlike car battery chargers and battery tenders that need AC power to operate, this charger is ideal for vacation-saving power whether you’re in an RV, backpacking, camping or engaging in any other outdoor activity.  Whether you’re using it all the time to charge all your portable electrical devices, trickle-charging your vehicle battery, or just want to have it on hand for emergency preparedness such as power outages, a portable solar battery charger may just make the difference between a trip-ruining moment and a stress-free family outing.
