Mophie on Tuesday announced its first case that serves not only as a battery pack, but also as a waterproof case. It’s called the juice pack H2PRO and is currently available for pre-order direct from Mophie.

The juice pack H2PRO provides up to 100% additional battery life for the iPhone 6, thanks to its built-in 2,750mAh battery, which Mophie says is good for up to 10 hours of web browsing, 14 hours of talk time, or 50 hours of additional music playback. Mophie said that the pack actually “exceeds military standards for protection” against drops, and has an IP68 rating that means it should withstand dust and water immersion at depths up to 1.2 meters for 30 minutes. It also features an anti-glare screen so that you can use it outdoors without issue.

The juice pack H2PRO will be available in black for $129.95; you can pre-order it by hitting the source link below, and Mophie said it expects units to begin shipping in late May.
