Moment combines mobile photography with battery cases with the Battery Photo Case-- a self-descriptive iPhone 7 case, with two mounting slots matching the iPhone 7 Plus' dual-lens setup.
The slots allow users to add Moment lenses to either of the two iPhone 7 Plus camera (but not simultaneously). An iPhone 7 version featuring one mounting slot is also available. A new lens-locking interface clicks lenses in place. Customers can attach previous Moment lenses through a small adapter, although the company says the lenses will be reworked in the future for use with the new interface.
As for the battery, the iPhone 7 version carries a 2500mAh power pack, while the iPhone 7 Plus version clocks at 3500mAh. Case construction is in plastic and rubber, with a Lightning port at the bottom passing power to the phone.
