Did Mophie's 4,000mAh Juice Pack Powerstation not hold enough extra battery power for you, warrior of the road? Well, today you're in luck. The company has just introduced its new Pro variant, packing a massive 6,000mAh of total juice. Like its older brethren, it'll charge mostly any device over USB (even supplying pass-through power when you need to plug it in), and switches between 500 mAh, 1A and 2.1A to preserve its total capacity. The real kicker, however, is its "impact-restistant" casing, made of steel, aluminum and rubber, along with its "water-tight" USB ports. Notably, the Pro is also IP65-certified -- effectively ensuring a venerable level of protection from liquid, shock and dust. No word on pricing or availability just yet, but we're sure many a journeying LTE user will want one to store in their backpack ASAP.
