Charge the ring with the supplied magnetic USB-A cable; a full charge takes around one hour.

Recommendations

For accurate heart rate and SpO2 measurements, ensure the ring fits snugly but not tightly on your finger and stays in place during monitoring. Avoid exposing the ring to strong chemicals; rinse after swimming in chlorinated water. Keep the QRing app updated for best compatibility and feature improvements.
