Faulty USB port or outlet

If you haven't done so, try a different port. A UL-certified wall charger will also work. Don't use a USB hub.

Certain Fitbit devices cannot be fully powered off. Because certain models will remain on, be very careful when cleaning these types of devices.

It is recommended to occasionally clean your Fitbit to ensure all sensors and connectors can continue to function properly.

  1. Clean the charging contacts on the back of your device to ensure they stay bronze or gold in color. To do so:
    • Use a toothpick or a toothbrush with rubbing alcohol.
    • Make sure not to scrape the contacts with a wire brush or anything metal, since this can damage the plating and cause corrosion.
    • If you use a toothbrush, dry with a cloth or tissue before charging.
  2. Clean the pins on your charging cable. To do so:
    • Soak a cotton swab with alcohol and press the swab to the pins carefully.
    • Make sure that no debris from the swab is left behind.
  3. Clean the removable pebble if you have a Flex series tracker. To do so:
    • Take the pebble out the wristband and clean it with a cotton swab and rubbing alcohol.
    • Dry it with a cloth or paper towel before putting it back in the wristband.

  1. Plug the charging cable into the USB port on your computer or any USB wall charger.
  2. Clip the other end of the charging cable to the port on the back of the tracker. The pins on the charging cable must lock securely with the port.

  4. You will know the connection is secure when the tracker vibrates and you see a battery icon on the display. Your Charge 2 will begin charging.
  5. Press and hold the button on your tracker for four seconds. When you see the Fitbit logo and the tracker vibrates, this means the tracker has restarted.
  6. Unplug your tracker from the charging cable.
