If the light on your cuffs is flashing red, this indicates that the battery is low. 

To charge your cuffs, simply use the charging cable and connect them to a power source.


You will be able to recognise whether The BFR Cuffs are charging via the light ring - a steady white light blinking on-off-on indicates that the cuff is charging. 


Your BFR cuffs will last up to 100 inflations - we do advise charging your cuffs prior to first use.


A quick note on power sources: The BFR Cuffs will charge when plugged into most devices, yet some higher-power sources (65+ watt laptop and mobile phone chargers) will not charge your cuffs.
