Hello @Freeney
Plug the charging cable that came with your Fitbit device into a USB port on your computer, a UL-certified USB wall charger, or another low-energy device. Attach the other end of the cable to your device. Charging your device to 100% may take 1-2 hours. on a Charge 5 hold the charging cable near the port on the back of the tracker until it attaches magnetically. Make sure the pins on the charging cable align with the port on the back of your tracker. The percent charged appears on the screen.
