One of the major drawbacks of relying on portable devices like the iPhone or iPad is that you're totally reliant on the built-in battery. Once that hits empty, you're done for the day. Fortunately, there are portable battery packs that allow you to keep your iPhone and iPad topped up throughout the day so they're always ready for action.
One such portable battery pack is the New Trent iGeek. This offers 9,900 mAh of power and it compatible with the iPhone 4S and iPhone 5 and the iPad 3, iPad 4 and iPad mini (as well as any other device that can be charged from a USB port, so long as you have the appropriate cable). It's fitted with two USB ports so you can charge two devices simultaneously.
It will set you back $65.95, but it will keep all your gadgets charged up and ready for use.
