Genuine Fitbit FB150 USB Dongle
The Fitbit FB150 USB dongle was a genuine accessory for older Fitbit trackers, but it is no longer sold directly by Fitbit. It allowed users to sync their fitness data with a computer running the Fitbit Connect app. The dongle was primarily used with older trackers before Fitbit shifted its focus to mobile app syncing.
Key points about the FB150 dongle
- Legacy device: The FB150 dongle is a legacy product. Most current Fitbit devices do not require a dongle and are designed to sync via Bluetooth with a smartphone or a computer with a built-in Bluetooth chip.
- Original purpose: It was used for wireless syncing with computers that lacked built-in Bluetooth capabilities. Users would plug the dongle into a USB port and run the Fitbit Connect software to transfer their data.
- Compatible models: The FB150 was compatible with several older Fitbit trackers, including the Fitbit One, Flex, Charge, Charge HR, Surge, and Alta.
- Limited functionality with newer models: For newer Fitbit devices, such as the Charge 5, the dongle is not supported. These devices are intended to sync with the mobile app for a full set of features, including access to Health Metrics and Daily Readiness Score (with a Premium subscription).
