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
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.
