Soundcore Motion Boom Plus lights: what each colour and pattern means
soundcore’s FAQ for the Motion Boom Plus (model A3129) explains its indicator light in answers to separate questions: red is about the battery (solid while charging, flashing when low), solid white is a full charge, and white and blue are also used when you join two speakers, by the Bluetooth button or by PartyCast. The FAQ uses red only for the battery, not for a fault. soundcore says a 5V/3A USB-C wall charger takes it to 100% in 5.5 hours, and that a speaker left unused for a long time may need at least an hour on charge before it turns on.
This page is for the Motion Boom Plus (A3129) only. soundcore’s pages for the Motion Boom (A3118) gave no light meanings when we read them, so its lights are not here.
