Unable to charge the speaker

  • Make sure that the AC adaptor is connected securely to the speaker. Then, make sure that the AC adaptor is connected securely to an AC outlet.

  • The speaker supports USB AC adaptors that are capable of delivering an output current of 3.0 A or 1.5 A. (Using a USB AC adaptor capable of delivering an output current of 3.0 A for battery charging reduces the charging time.) Be sure to use a USB Type-C® cable (compliant with the USB standard) that supports the output current of your USB AC adaptor. Use of a USB AC adaptor with an output current of less than 1.5 A is not guaranteed for battery charging. The charging time may vary depending on the ambient temperature or the usage of the speaker as well.

  • Depending on the type or specifications of a commercially available USB AC adaptor, if you use the speaker at a loud volume, the remaining power of the rechargeable built-in battery may decrease or the speaker may turn off even while the speaker is connected to an AC outlet by the USB AC adaptor. This, however, does not indicate a malfunction. If such a case occurs, turn off the speaker and let the battery fully charge itself before you use the speaker.
