A:AnswerCan't say for sure if it technically qualifies as Samsung's proprietary Adaptive Fast Charging, but it's fast. It passthrough wall charged my Note 9 (powered on/ screen off) from 0-100% in under 2 hours, and the case's battery itself charged my Note at a comparable rate.
A:AnswerI have a Galaxy Note 9 and the information on the box reads, "Slim protective battery case MADE for Samsung Galaxy Note9." the Mophie attaches piggyback on the Note9. Looks like part of the phone itself. Wrapping around back of the phone. Many of the S models are smaller than the Notes, therefore may not fit inside the Mobi housing.
