Mophie portable batteries are some of the best out there mostly because you can count on them to be reliable. The last thing you want is a cheap backup that fails you. The company's latest top-tier line packs integrated charge and sync cables into a slick design that might actually be worth the hefty price tag.
The new line of Powerstation Plus batteries comes in 3000, 5,000, 7,000, and 12,000 mAh models for $80 (£51), $100 (£64), $120 (£76), and $150 (£95). And in fairness, that's a lot more expensive than chargers from solid Mophie competitor Anker.
But what you're paying besides reliability is convenience: The Powerstation Plus has built-in charge and sync cables. (Both Lightning and Micro USB are available.) That means that in addition to charging your phone with the built-in cables, you can also use it to connect to your phone to your computer for a sync. Given that you're likely to use a Mophie when you're on the run and you need an emergency charge, cutting back on cable clutter is always a benefit. In this case, it's a benefit you have to pay for.
