If your apps don’t drain your battery in just an hour or two, then there’s a number of other reasons that just seem made up. You just want your battery at full power as much as possible.
There’s nothing wrong with being prepared, and with a Solar Backup Battery from Hammacher Schlemmer you’ll be ready to weather any storm. This portable battery can easily be attached to a window and uses the power of the sun to charge your electronic devices.
