Symptoms
- No charging light appears when plugged in
- Charging light blinks or flashes instead of staying solid
- Speaker won't turn on even after hours of charging
- Speaker charges but battery drains unusually fast
Likely causes
- CommonFaulty or incompatible charging cableA cable that's damaged or not rated for enough current can fail to charge the speaker.
- CommonDirty or debris-filled charging portLint, sand, or corrosion in the port can block a solid connection.
- PossibleBattery deeply discharged and needs extended time to wake upA speaker left uncharged for months may need 30–60+ minutes before showing any charging indicator.
- PossibleWeak or incompatible power adapter/USB portCharging from a low-power USB port (like some laptop ports) can be too weak to charge the speaker.
- Less commonDegraded or failed internal batteryBatteries lose capacity over time and can eventually fail to hold or accept a charge.
What to do
- Try a different charging cable, ideally the original one that came with the speaker.
- Inspect the charging port for lint, sand, or debris and clean gently with a dry brush or toothpick.
- Plug into a wall adapter rather than a computer USB port for a stronger charge current.
- Let the speaker charge undisturbed for at least an hour before checking for any sign of life, especially if it's been unused for a long time.
- Try a different wall outlet and power adapter to rule those out.
- Check the speaker's manual for what the charging light pattern should look like to confirm whether it's actually charging.
Tools and parts
- Soft brush or toothpick (for port cleaning)

When to call a pro
If the speaker shows no charging indicator at all after trying multiple cables, ports, and an extended charge time, the internal battery has likely failed and needs replacement.
