Extend Your Battery Life (PDF/ePub/MOBI Bundle)

$2.99

Few things in life are as frustrating as running out of juice at the most inopportune times. You need to make an important call just as your phone's screen goes dark. You have to finish an important document just as your laptop's battery runs out. You have your camera poised to snap the perfect shot but when you press the shutter, nothing happens.

NOTE: This Superguide is available as a PDF/ePub/MOBI .zip bundle. To purchase and download it, you'll need to be on a Mac or PC--mobile devices like the iPad and iPhone cannot open .zip files. But you can open it on your Mac or PC, and transfer it to a variety of devices. Learn more by checking out our Read Me. If you'd like to purchase and read our Superguide directly on your iPad, we suggest that you get it as a PDF.
