This is a 3 year old refurbished model of a discontinued product. Amazon has the Anker PowerCore 13000 Portable Charge device for basically the same price, more mAh(13000 to 12000), both ports support fast charging instead of just one. Not to mention the reviews are much better (11% 1 star for the Morphie, 1% 1 star for the Anker).
It seems the days of the super Woot deals are ending, as your scenario of New Amazon products besting Woot deals,… is becoming more and more common !!
