In 8K PRO, the e-liquid in your disposable will not be wasted if the battery dies. The rechargeable design extends the life of the STLTH disposable, and the display screen makes it simple to determine when it's time to charge the device.
When your device is charging, the LED screen will display the current battery level. The battery charge will increase by 5%. When the battery level is at 0% it will display "Lo" which means it is time to charge the device.
When the device is fully charged the screen will turn off.
