Can’t charge the COROS watch?

  • If the watch doesn’t power on and the screen is black even with charging, please follow the steps below to restart the watch.
    • Charge the watch for over 2 hours even if the screen doesn’t turn on.
    • Remove the charging cable from the watch (this step is very important).
    • Press and hold the knob for over 15 seconds or until the COROS logo shows up.
    • Please don’t press both buttons on your COROS watch at the same time. Otherwise the COROS watch will enter Inactive mode and will not respond to normal operation or charging. Please power off the watch if you plan to stop using it - main watch face > System > More > Turn Off.
  • If the watch can’t maintain a stable charging status, please check if the power outlet voltage is too high/low. Switch over to a computer or a standard USB power adapter and try again.
  • Please check if the metal pins are clear of debris. Disconnect the cable from power and rinse the watch and the cable. Let them air dry and try again.
