Accessory maker Mophie appears to have a Qi-certified Mophie Juice Pack Air for iPhone X in the pipeline, as it has obtained certification from Wireless Power Consortium, as first spotted by Mac Otakara.

The certification says it’s a “form fitting case for the iPhone X”, while it notes a battery capacity of 1720 mAh, which says will provide “an additional 9 hours of talk time”. This battery capacity is 32% in size compared to the 2525 mAh battery found in Mophie’s Juice Pack Air for iPhone 7.

With Qi-certification, it means the case can charge your iPhone X wirelessly, without the need to plug into the phone’s Lightning connector port. This may result in a charging case design that is slimmer than before, as a bottom bezel to accommodate a Lightning connector, as seen in existing Juice Pack Air models, will no longer be required.

You can bet Mophie has plans to release similar Juice Pack Air models for the iPhone 8 and iPhone 8 Plus, which also support Qi wireless charging.
