Just received a SoundCore Sport XL yesterday. I read the instruction manual, and plugged in the unit to fully charge. The manual explains that “one flashing white light” indicates charging and when the light turns off, it is fully charged. I left the unit charge overnight (8 hours), and the three white lights are solidly lit up, not blinking, but lit. Is it fully charged?
If the lights are all on (and not blinking), then your speaker is fully charged. I believe after a certain amount of time, they eventually all turn off.
If you have any other questions, please let us know!
