You might want to be careful. I have not had any luck with this product. First Mophie item ordered (15,000 mAh Powerstation 8x) did not work correctly (only one port charged) and was sent the 3,000 mAh charger today instead of the 12,000 mAh ordered.
So far Mophie is 0-2 on chargers ordered through Woot.
YMMV but be forewarned.
