Troubleshoot “Low power” and “g.co/cast/power” screens

The warning 'low power' or the link 'g.co/cast/power' appears on your TV screen when your Chromecast with Google TV doesn’t have enough power to function properly. To troubleshoot, follow the steps below:

  1. Check that your Chromecast with Google TV is plugged into the power adaptor that came with it. If it’s plugged into your TV’s USB port or a different adaptor, it might not be getting enough power. 
  2. Check that the power adaptor is plugged into a reliable power socket. 
  3. Check that the cable also came with Chromecast. If you use a different cable, it might not be supported.
  4. Check that the cable is completely plugged into both the adaptor and the Chromecast.
  5. Reconnect the cable into both the adaptor and the Chromecast: 
    1. Unplug the cable from the Chromecast and the adaptor And then wait 5 seconds.
    2. Plug the cable into the adaptor first And then plug it into the Chromecast.
  6. Check that no USB Type-C hubs or switches are between the Chromecast and power adaptor. They can affect the power capability or power delivery compatibility.
