Best Answer: The Mophie Juice Pack Access comes in three models: The XR model is 0.75 inches thick, the XS Max model is 0.71 inches thick, and the X/XS model measures 0.69 inches thick. Regardless of which model you get, this will make any phone in the iPhone X line feel substantially thicker since most of these iPhones are about 0.3 inches thick on their own. However, that's the price you pay if you want your phone battery to last a little longer.Gimme some juice!: Mophie Juice Pack Access iPhone X/XS ($100 at Amazon)Power station: Mophie Juice Pack Access iPhone XR ($100 at Best Buy)Charge it up!: Mophie Juice Pack Access iPhone XS Max ($100 at Amazon)
