Initial Troubleshooting Steps

1. Check that your charger is the correct one for your Oura Ring. The Oura Ring 4 charger cannot charge Oura Ring Gen2 or Oura Ring Gen3, and the older generation chargers can not charge Oura Ring 4
2. Ensure your ring is resting properly on the size-specific dock. If it is, a small light will appear on your charger
3. Try using a different USB-C charging cable
4. Turn the USB-C cable 180 degrees and reinsert it in the ring charger
5. Try using a different power source, such as a USB wall plug, laptop, or power brick

The USB charging power cord is intended to be supplied by an external 5Vdc supply that complies with EN 62368-1 standard.

Oura Ring 4 Chargers

The Oura Ring 4 charger has a self-test function to ensure it is working correctly. To test the charger, plug the charge in without putting the ring on it.

• If the charger light does not illuminate or blinks red, try using a different power source, such as a USB wall plug, laptop, or power brick. You can also try using a different USB-C charging cable
• If your charger light turns white and then fades away, your Oura Ring 4 charger is working correctly. Place your ring on the charger
  

If the charger light blinks 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 your Oura Ring 4 charger is not working correctly or your Oura Ring 4 is not connecting to the app, please contact our team.

Gen3 Chargers

The Gen3 charger has a self-test function to test if the charger is functioning when it is plugged in. To test the charger, plug the charger into the power without putting the ring on it.

The white charger LED should light up once and then fade away.

• If your charger illuminates, it is functional and your ring is likely causing the issue
  
• If the charger light does not illuminate, this likely indicates that the charger itself is defective

Gen3 chargers also include a red-green-blue (RGB) LED to help indicate their charging status.

If the light is blinking red while the ring is on the charger:

1. 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)
2. Make sure your ring has the latest firmware installed. A message will appear at the top of your Oura App's home tab if a firmware update is available
3. Try performing a factory reset of your Oura Ring. See this article for factory reset instructions

If you still see a blinking red light after trying the above steps, there may be a problem with your ring. Please contact our team with information regarding which troubleshooting steps you've already taken.

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

Gen2 Chargers

If you have a Gen2 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 the charger light does not illuminate, this likely indicates that the charger itself is defective

Please contact our team with information regarding which troubleshooting steps you've already taken.
