The mophie juice pack helium is an all new, all lighter and thinner battery charging case for the lighter and thinner iPhone 5. It features a 1500mAh, barely more than the iPhone 5's built-in 1440mAh battery, and when translated into external battery pack terms, that packs roughly an 80% refill charge.
For those whose iPhone batteries lived -- or died -- on the extra power provided by a mophie juice pack case, good news -- mophie has just announced the juice pack helium. Why helium? Because it's lighter than air, as in the previous generation juice pack air, of course. It's a 1500mAh battery, which will replenish an iPhone 5 up to 80%, but it's packed in a case that's svelter than ever before.
