Sorry to hear your Bluetooth speaker is not charging. Here are some things to try:
- Try another charging cable
- Try another USB port or USB charger
- Leave the speaker on the charger for an hour to see if it changes (if the battery is completely discharged, it may take 30 minutes or so to begin working again)
