The simplest way to conserve battery power is to turn your iPad off every time you know you don't need it for an extended period of time. Although the iPad's battery can last approximately 10 hours, you may want to invest in a battery pack. Although these external battery packs may be cumbersome to lug around, you can use them in emergencies when you need to use your iPad but find that its power has drained away.

Rather than rely on a battery pack, you could also buy a solar panel that can recharge your iPad as long as you can place the solar panel in the sun. If you combine conservation techniques with additional power sources, there's no reason why you should ever run out of power for your iPad.
