Mophie released a pair of new battery packs today, and the company is finally embracing the USB-C PD specification for fast charging. The new PD pack comes in two sizes: the $59.95 Powerstation PD, which offers 6,700mAh of charge, and the larger $79.95 Powerstation PD XL, which has 10,050mAh of battery capacity.

Cleverly, Mophie is taking advantage of the dual nature of USB-C, and each pack only offers two ports: a single USB-C port, which can be used to charge devices plugged into the Powerstation PD (at up to 18W) as well as recharge the pack from a wall brick (at up to 15W). There’s also a legacy USB Type-A port, which can power devices at up to 12W.
