Small Solar Power Supply for Small Device(s)

There are many advantages to storing electronically but remeber that Kindle and ipad etc all use LiPo or LiIon batteries that have a useful shelf life of about five years, maybe a few longer, probably not past 10 years. The batteries can not be replaced as it's assumed you'll have upgraded to a new one before this and the new batteries age just as fast 'on the shelf'. You may be able to still use the device only when the charger is plugged in beyond this but I've seen some devices where you couldn't even do this.
