How do I charge my Fitbit device?

Plug the charging cable that came with your Fitbit device into a USB port on your computer, a safety-certified USB wall charger, or other safety-certified, low-energy power source. Attach the other end of the cable to your device. Charging your device to 100% may take 1-2 hours.​
