Mophie released its third generation external battery ‘powerstation’ lineup. Made from a sleek durable high-grade aluminum, the all-new external batteries are a lot slimmer than the previous models. Whether you need to charge your smartphone, tablet, or other USB device, the external battery’s 15W charging input and output identifies the device’s power needs and delivers the most optimal charge possible. The compact size of the battery is possible because of cutting-edge, high-density battery cells. Mophie also offers a power app to monitor and manage both the battery life of a phone and the ‘powerstation’ battery, that notifies users when charging is complete or the power is low.
