Mophie is the top seed of this product category, but there’s no good reason to get a Mophie Juice Pack over the Lenmar Meridian. While their Juice Pack series of iPhone 5 battery cases is pretty impressive, none of them can match the Meridian’s price and performance. Even their flagship model, the just-released Juice Pack Plus, only has a 2,100 mAh battery—that’s still 200 fewer than in the Meridian. Besides not being able to charge as well, the Plus costs $120, or $65 more than the Meridian. The Plus gets points for having integrated buttons that make it easy to operate the phone with the case on, but the price hike and second-place performance make it a much worse value than the Meridian.
Mophie also has two other cases: the Helium and the Air, which have 1,500 mAh and 1,700 mAh batteries respectively. The Air costs $100 and the Helium is $70, but because they can’t come close to fully recharging an iPhone, we wouldn’t recommend either to anyone who needs really extended battery life.
Their newest addition, the Mophie Space Pack, packs the same 1,700 mAh battery as the Air and 16 or 32 GB of extra space. Reviews, like this one at TechCrunch, say it’s basically a souped-up Air. We already don’t recommend the Air, and without some seriously glowing reviews, the Space Pack is no different: For $95 more than the Meridian, you’re paying for a worse case and some extra space. That’s just not worth it.
