Hello everyone, to charge your Blaze I recommend plugging your charging cable into a USB port on your computer or other low-energy device. If necessary, you can use a UL-certified USB wall charger. Don't use a USB hub or battery pack to charge, and only use the charging cable that came with your tracker.
The Blaze has a rechargeable lithium-polymer battery. If your battery is low, charging fully may take one to two hours. To charge your Blaze:
- Plug the charging cable into the USB port on your computer.
- Remove the tracker from the wristband. To do so, push the screen gently so that it detaches from the frame.
- Put the tracker inside the charging cradle with the screen facing towards you and the four gold prongs aligned.

- Close the cradle cover.

- Look for a large battery icon that appears temporarily on the display to let you know that charging has started. It gives an indication of how low your battery is to start, and a small battery icon remains in the top left corner while charging so you can check progress. A large green battery icon means the battery is full.

To help you pick a good time for charging, note the following:
- The top left of your Blaze screen shows a battery icon that represents the charge level at the last time you synced.
- You can also see your battery level at any time on your Fitbit dashboard.
- You can receive a push notification on your mobile device or an email when your battery is low. To choose your preference, go to the Notifications of your fitbit.com dashboard settings.
Hope this helps! 😉
