Symptoms
- No charging light when plugged in
- Charging light on but battery percentage doesn't rise
- Speaker won't turn on even after hours of charging
Likely causes
- CommonFaulty or underpowered charging cableA cheap or damaged cable can fail to deliver enough power to charge.
- CommonDirty or damaged charging portLint, moisture, or corrosion in the port can block a good connection.
- PossibleAged battery no longer holding chargeBatteries degrade after hundreds of charge cycles, especially in speakers used outdoors.
- PossibleWeak power sourceSome laptop USB ports don't supply enough power to charge larger speakers.
- Less commonWater damage from splash exposureEven water-resistant speakers can develop internal corrosion over time.
What to do
- Try a different cable and wall adapter, avoiding low-power USB ports on laptops.
- Inspect the charging port for lint, moisture, or corrosion and clean gently.
- Let it sit charging for at least an hour before assuming it won't take a charge.
- Press and hold the power button for 10–20 seconds to force a restart while plugged in.
- Check if the speaker has a reset button or combination to reset the battery management system.
- Note if it charges but drains unusually fast, which points to battery wear rather than a charging fault.
- Contact the manufacturer if it's within warranty since batteries often qualify for replacement.
