When do I need the wireless sync dongle?
Fitbit Store.

Note that Blaze customers who want to use a computer don't need a dongle if these conditions are met:

• The computer is running Windows 10.
• The Fitbit app for Windows 10 is installed.
• Blaze is in the charging cradle.
• The other end of the cradle is plugged into a USB port on the computer.

In this scenario syncing occurs while Blaze is in the charging cable. It only works in conjunction with the Fitbit app for Windows 10.
