Mophie juice pack powerstation PRO: A big gas tank for your gizmos

ImageWe test a lot of external power packs here at the top-secret TUAW labs, most of which are just powerful enough to top off an iPhone or iPod touch. But what if you need enough juice to top off a couple of iPhones or an iPad? That's where Mophie's new juice pack powerstation PRO (US$129.95) comes in handy. Read on for a full review and a chance to win a juice pack powerstation PRO.

The juice pack powerstation PRO is to most external power packs as a gasoline tank truck is to the tank in your family car. It has a capacity of 6000 mAh, which is over four times the capacity of the 1432 mAh battery in your iPhone 4S. Imagine being able to completely charge an iPhone 4S four times from the powerstation PRO, and you have a pretty good idea of its capabilities.

That won't completely recharge a new iPad, which has a huge 11666 mAh battery, but it will extend the operating time by another five hours or so. The original iPad battery (6600 mAh) and iPad 2 battery (6930 mAh) will see almost a doubling in operating time from the juice pack powerstation PRO. The pack pumps out energy at 2.1 Amps, about what you'll get from the standard iPad power brick.

The powerstation PRO is incredibly well-built -- in fact, it's IP-65 rated, which means that it's protected against dirt, sand, and water. Sure, you won't want to bring it into a bathtub with you, but it could probably withstand the spray from a shower as the charging and output ports both have their own watertight seals. The entire power pack is made of aluminum and steel with a rubber-like impact resistant exterior.

Size-wise, the powerstation PRO is only 2.63" x 4.53" x 1.03" in size and weighs 7.6 ounces. It's small enough to fit in a pocket, although I wouldn't recommend putting into a pants pocket unless you don't mind getting strange looks. A set of four LEDs on the front of the case act as a "fuel meter" to tell you the charge level of the powerstation PRO.

How did the powerstation PRO work? Just great. I didn't have a chance to drop it down a hill and into a river like the guy in the video below, but I was quite impressed with both the speed with which it charged my iPhone and the rugged looks of the case.
