The Juice Pack PRO

A companion to their ultra-rugged Powerstation PRO, this dual-purpose iPhone case holds 25% more power than previous models (for a total of ~1.5 full charges), and comes jacked with perks like an anti-glare screen and waterproof speaker covers that offer an unprecedented, military spec-exceeding level of protection from a whole smattering of frequently encountered annoyances like moisture, sand, and, yawn, gunfire vibration.
