On the USB charger, there should be small text that includes the amp (A) or milliamp (mA) rating of the charger. This rating can vary among chargers. A higher rating (i.e. 1.5 A / 1500 mA) will charge your product more quickly while a lower rating (i.e. 0.5 A / 500 mA) will charge your product more slowly—or might not charge it at all. Try another charger that meets the power requirements found in your product specs.

Disconnect and reconnect the USB cable at both ends, ensuring it is firmly connected. Allow at least an hour for the speaker to charge after the connections have been reestablished.

Disconnect the charging cable from the charging cradle then connect the cable directly to the speaker. If the speaker begins charging, there may be an issue with the cradle.

When your product is connected to the charging cradle, USB audio and charging do not work.

Try connecting your product with a different USB cable to determine if there is an issue with the first cable.

Make sure to play the speaker at a moderate volume (around 50%) for at least 10 minutes while on battery power. Then try charging the unit again.

Regardless of the issue you are experiencing with your product, try updating it. Visit btu.Bose.com and follow the instructions to ensure your product has the latest features and enhancements.
