Mophie's new Juicepack Powerstation Pro is a ruggedized, water- and dust-resistant, 6,000mAh external charger for your mobile devices. It has both standard and micro USB, so it'll accommodate a wide variety of phones and tablets, but it's not meant to power up your laptop. The sealed ports were definitely a nice touch, and the charger felt surprisingly light for the amount of juice it packs. Mophie tells us that the Powerstation Pro will be available in February or March for "around $150."
