Charging the speaker

The speaker is capable of running on power either from an AC outlet connected by the AC adaptor (supplied) or from the rechargeable built-in lithium-ion battery.

When using the speaker for the first time, be sure to charge the built-in battery for more than 1 hour before turning on the speaker.

With the built-in battery charged in advance, you can use the speaker solely with battery power.

  1. Connect the speaker to an AC outlet to charge it.

    Connect the supplied AC adaptor to the DC IN 5V port on the speaker and an AC outlet.

    Battery charging starts and the CHARGE indicator lights up in orange. Charging will complete in about 5 hours* and the indicator will turn off.

    * Time that is required to charge the empty built-in battery to its full capacity when the speaker turns off.


    After you disconnect the AC adaptor from the speaker upon completion of battery charging, be sure to close the cap securely.

    The cap plays a very important role in maintenance of the waterproof and dust proof performance.

Checking the charging completion

If the built-in battery is fully charged when you connect the speaker to an AC outlet, the CHARGE indicator lights up in orange then turns off after about 1 minute.

Checking the built-in battery level of the rechargeable built-in battery

  • After pressing the BATT (battery) button behind the cap on the rear side of the speaker, when the speaker is turned on, the voice guidance listed below is output from the speaker depending on the remaining built-in battery power.

    80% or more: “Battery fully charged”

    60% or more: “Battery about 70%”

    40% or more: “Battery about 50%”

    20% or more: “Battery about 30%”

    Less than 20%: “Please charge”

    Hint

    • By using “Sony | Music Center,” you can activate/deactivate the voice guidance associated with the remaining battery power that you hear when you turn on the speaker.

  • When using the Android smartphone with OS 8.1 or later installed

    When the speaker is connected with the Android smartphone via an HFP (Hands-free Profile) BLUETOOTH connection, tap [Settings] - [Device connection] - [Bluetooth] on the smartphone. The remaining battery power of the speaker is displayed along with the connected BLUETOOTH device name. For details, refer to the operating instructions supplied with the Android smartphone.

    Note that the remaining battery power displayed on the smartphone may vary from the actual remaining battery power of the speaker. Consider this information as a reference.

  • When using the iPhone/iPod touch with iOS 10.0 or later installed

    While the speaker is connected with the iPhone/iPod touch via an HFP (Hands-free Profile) BLUETOOTH connection, the remaining battery power of the speaker is displayed on the widget screen of the iPhone/iPod touch. For details, refer to the operating instructions supplied with the iPhone/iPod touch.

    Note that the remaining battery power displayed on the iPhone/iPod touch may vary from the actual remaining battery power of the speaker. Consider this information as a reference.

Built-in battery life (using a BLUETOOTH connection)

  • About 24 hours

    The volume level of the speaker is set to 31.

    The lighting function is set to off.

    The sound effect is set to STAMINA.

  • About 14 hours

    The volume level of the speaker is set to 30.

    The lighting function is set to on. (factory default settings)

    The sound effect is set to EXTRA BASS. (factory default settings)

  • About 4 hours

    The volume level of the speaker is set to maximum (50).

    The lighting function is set to on. (factory default settings)

    The sound effect is set to EXTRA BASS. (factory default settings)

The built-in battery life above is measured using our specified music source.

Actual performance time may vary from the listed time due to the volume, songs played, surrounding temperature, and usage conditions.

When the built-in battery is running low

When the voice guidance says “Please charge” and the CHARGE indicator flashes slowly, the built-in battery is running low and needs to be charged. In this state, the speaker cannot supply power to other devices.

Using a commercially available USB AC adaptor for battery charging

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.

Hint

  • A speaker that is in use can be charged if it is connected to an AC outlet via the AC adaptor (supplied). In this case, it may take longer to charge the built-in battery compared to when the speaker is turned off depending on the conditions of use. Therefore, it is recommended to turn off the speaker when charging.

Note

  • When you use the speaker at a loud volume, the built-in battery may run low even if the speaker is connected to an AC outlet. If you want to use the speaker while charging, lower the volume of the speaker. Otherwise, turn off the speaker and charge the built-in battery sufficiently.

  • When you use the speaker at a loud volume for a long time, the built-in battery may run low even if the speaker is connected to an AC outlet. As a result, sound becomes low. This is not a malfunction. Turn off the speaker and charge the built-in battery sufficiently.

  • 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.

  • The maximum power output will be lower when the built-in battery is running low.

  • In an extremely cold or hot environment, charging stops for safety. If charging takes a long time, it also makes charging of the speaker stop. To resolve these issues, disconnect the AC adaptor (supplied), and then connect it again within an operating temperature between 5 °C and 35 °C (41 °F and 95 °F).

  • Do not charge the speaker's built-in battery in places where water may splash on it. The supplied AC adaptor as well as the USB port and the AUDIO IN jack behind the cap are designed neither for waterproof nor for dust proof.

  • Even if you do not intend to use the speaker for a long time, charge the built-in battery sufficiently once every 6 months to maintain its performance.

  • The multi-device connection is not compatible with HFP (Hands-free Profile). Therefore, when using the multi-device connection, the remaining battery power of the speaker is not displayed on the Android smartphone or the iPhone/iPod touch.

  • When the Android smartphone is configured to use only A2DP (Advanced Audio Distribution Profile) for establishing BLUETOOTH connections, the remaining battery power of the speaker is not displayed on the smartphone.
