On Alibarbar devices (particularly the INGOT 15000 and similar models with a display), FL stands for Flavor Lock.

When you see “FL” followed by a number on the screen, it indicates that the Flavor Lock feature is active – the device automatically holds the best power output to maintain consistent flavour, preventing burnt or dry hits even during chain vaping. Some Reddit users have also noted it can appear when the device has been idle for a short time and the chip “locks” the flavour profile to avoid coil overheating.
If you’re seeing “FL” without a number or it’s blinking, it may simply be entering or exiting standby mode, or the Flavor Lock setting is being switched on/off.
In short: FL = Flavor Lock, a feature designed to protect your coil and keep taste consistent.
