It’s not a bad idea to keep a small battery pack in your backpack or purse at all times. You’d be surprised how often a little extra juice can save the day.
But what if you have bigger needs? Laptop-scale needs? What if that 12-hour international flight doesn’t have seat outlets? What if you’re doing a lot of work on your Macbook at an outdoor venue and you have no idea if you’ll have access to an outlet?
A large power pack with an AC plug, like Mophie’s new Powerstation AC, may be just what you need.
