A:AnswerThe Morphie Juice Pack Reserve is going to be 1,840mAH and have about or more than 60% additional battery and be slightly less heavy at 2.65oz (75.1g) and a little smaller in size then the Juice Pack Air. Also the Juice Pack Reserve only comes in Matte color options. The Morphie Juice Pack Air is going to be 2.750mAH and have at or more than 100% additional battery and be slightly larger and heavier (3.50oz/99.2g) than the Reserve, however the Air gives color options in gloss and matte. I would suggest maybe going to the morphie website and seeing if they have a comparison tool available to give more details. Basically the Air is going to be bigger and heavier then the Reserve and also give you more battery charging but will also come at a higher cost than the reserve .
