Introducing
Power That Moves With You.
O-Ring is being designed to provide supplemental power through a compact magnetic accessory.
Magnetic Attachment. Supplemental Power.
O-Ring is intended to attach magnetically to the back of a compatible phone. Once activated, it is designed to deliver supplemental power while the phone remains in use — no cable required during use.
This describes the intended design only. Charging behavior, speeds, runtime, efficiency, and device compatibility have not yet been technically validated.
