mophie's Powerstation XXL Battery Pack charges up to three mobile devices at the same time and sports 20,000mAh of power, which can charge most smartphones up to seven times. The Powerstation XXL comes with smart adaptive charging technology that identifies the fastest charging speed for your devices and delivers up to 2.1A of power. Two of the three USB ports provide up to 2.1A, and one USB port offers 1A. Moreover, mophie has outfitted it with a rose gold aluminum enclosure for durability.
For safety, digital power management circuitry is on board to provide short-circuit, overcharge, and temperature protections. With a pass-through charging feature, the battery pack will charge your device first and then itself while recharging from your USB wall charger and an included 9" micro-USB cable. Additionally, power indicators let you know how much power is left and when the battery is fully charged.
