The manufacturer recommends frequent charges for short periods of time after the initial charging of the Fitbit device. It takes around one to two hours for a device go from an empty to fully charged state. A full charge lasts three to seven days.
Owners charge their Fitbit devices using powered base stations. The base station plugs into a USB power source such as a computer. A USB adapter, such as those used with smartphones, allows charging of the Fitbit from a standard wall outlet, while a DC-to-USB adapter lets the Fitbit owner use a vehicle power port for on-the-go charging.
