A USB backup battery in your favorite dad’s daily carry gives him the superpower of unlimited battery life. The Mophie Powerstation 4000mAh sits in your bag until it’s needed, quietly biding its time. Then, when his phone runs out of juice, he plugs into the Mophie, and before he knows it, he’s back to full charge. The Powerstation will charge an iPhone 5 battery more than twice, or most iPad batteries a time and a half. I like the Powerstation better than the phone-specific case chargers because this will charge just about everything I carry on a day-to-day basis.
