Compatibility and sizing
The case is designed for Oura Ring 4, including Titanium and Ceramic models. Oura says it is not compatible with earlier-generation rings, so it is not an option for Gen 3 or Gen 2 owners. The case is size-specific: choose the case size that matches your Oura Ring 4 size.
Charging capacity and time
Oura says the case stores up to five full ring charges. This is a manufacturer-stated maximum, not a guarantee of five charges in every situation. Oura lists 90 minutes for a full case charge and 90 minutes for a full ring charge; the time to charge a ring can depend on its starting battery level.
