Troubleshoot Charging Issues

Having trouble charging your Oura Ring? This article contains several fixes and recommendations for charging issues.

Initial Troubleshooting Steps
Charger or Ring Issue?
Gen3 Chargers
Charger Test

If you need to purchase a new charger, please contact our team here. Be sure to indicate the proper charger size based on your current ring size. To check your ring size, look on the inside of your Oura Ring (listed next to the QR code), or tap the ring Icon_Ring_Battery.png in the upper right-hand corner of the Oura Home Icon_Home.png tab and swipe left.

Initial Troubleshooting Steps

  1. Ensure your ring is resting properly on the size-specific dock. If it is, a small light will appear on the front of the charger.
  2. Try using a different USB-A to USB-C charging cable.
  3. Turn the USB-C cable 180 degrees, and reinsert it in the ring charger.
  4. Try using a different power brick or source. The USB power cord is intended to be supplied by an external 5Vdc supply that complies with IEC 62368-1 standard. The power available to the equipment should not exceed 15W after 3 seconds.


Charger or Ring Issue?

If the initial troubleshooting steps didn't work, the next step is to determine the cause of the issue—ring or charger.

Gen3 Chargers

Gen3 chargers include a red-green-blue (RGB) LED to help indicate its charging status:

LED Color Reference (Please note, this color functionality is not supported when charging a Gen2 ring on a Gen3 charger.)


If the light is blinking blue: your ring is not currently paired to a device, and is ready to connect to Bluetooth. You should see this under two circumstances:

  1. you’re setting up your ring for the first time or
  2. you’ve performed a factory reset on your ring and did not pair it to your device afterward.

If the light is blinking red while the ring is on the charger: take the ring on and off the charger a few times to see if you’re able to establish a proper charging connection (indicated by a flashing white light). If you still see a blinking red light after several tries, there may be a problem with your ring. Please reach out to our team here.

Charger Test

If you have a Gen2 charger, or the above steps do not solve the issue with your Gen3 charger, you can try a simple home charger test:

  1. Begin by plugging your Oura Ring charger cable into a power source.
  2. Next, place the metal end of a separate USB cable in front of where the ring usually sits, above the light, as displayed in the graphic below.

Note: You’ll need to ensure that the metal portion of the USB cable is pushed up against the center of your charger, where the Oura Ring sits. If the two are not touching, the light source will likely not be triggered on.


If you’re unable to get your charger light to turn on using steps 1 and 2, try placing your ring on the charger one last time to see if the charger light illuminates.

  • If your charger illuminates, it is functional and your ring is likely causing the issue. If this is the case, please submit a request and our team will provide assistance as soon as we can. 
  • If the charger light does not illuminate, this likely indicates that the charger itself is defective. Please provide a photo/video of the troubleshooting shown above when submitting a request to our team so when can verify the issue.

Keep in mind: chargers are covered under the same warranty that comes with your Oura Ring. If we’re able to verify you have a defective charger via photo/video evidence, we will provide you with a replacement.
