Overview

  • Chargers are size-specific
    Your Oura Ring 4 size can be found on the inside of your Oura Ring 4.
  • Charging time
    Your Oura Ring 4 typically charges fully in 20-80 minutes, depending on its current battery level.
  • Battery level in Oura App
    You can check the battery level by tapping the battery icon in the upper right-hand corner of the Home tab.
  • Charge level before going to bed
    It’s recommended that your Oura Ring 4 be charged to at least 30% before going to bed.
  • Connect with USB C
    Connect the USB cable to your charging dock and plug the other end into a power source, such as a USB wall plug, laptop, or power brick.
  • Place Oura Ring on charging dock
    The LED will pulse white while your smart ring is charging.
  • Learn about the notifications
    When the LED turns green, your ring is fully charged. You’ll receive a push notification from your Oura App when charging is complete. This also applies for low battery notifications.
  • Troubleshoot your charger
    If the LED doesn’t light up, check to see that your charger’s cable is properly connected and your ring is positioned correctly, ensuring good contact between your ring and the dock.
  • Power cord compliance
    The USB charging power cord is intended to be supplied by an external 5Vdc supply that complies with IEC 62368-1 standard.

Charges fast - Great charger for the Ring 4. I thought I could use it with the newer ring 5 of the same size but you can't.
