Note

  • As long as the speaker is connected to an AC outlet by a USB PD compatible AC adaptor, the speaker's built-in battery is capable of charging itself even while the speaker is turned on.

    However, depending on the usage of the speaker, it may take a long time before charging completes. It is recommended that you turn off the speaker before battery charging.

  • When you use the speaker at a high volume, the speaker consumes more battery power.

    As a result, the following may occur.

    • Remaining power of the built-in battery decreases faster than usual.

    • The speaker may turn off sooner than expected.

    However, this is not a malfunction. Fully charge the speaker before use.

  • For safety reasons, the speaker automatically stops charging in the following cases.

    • When the speaker is charged in an extremely cold or hot environment

    • When charging takes too long

    To resolve this issue, disconnect the USB cable and connect it again when the battery charging temperature is between 5 °C and 35 °C (41 °F and 95 °F).
