If you plan on making extensive use of your iPhone during your workflow, you’ll need a backup battery.

Amidst the bazillions of iPhone and iPod batteries peppering the CES floor, I stumbled across the HyperMac Nano. Its small and sexy design seemed like a natural companion for an iPhone.

Many people (including myself) use iPhone cases with built-in external batteries… but sometimes, those cases cause as many problems as they solve. So, it may be worth having something like the HyperMac Nano on hand.
