As long as the speaker is connected to an AC outlet by a USB AC adaptor (commercially available), the speaker's built-in battery is capable of charging itself even while the speaker is turned on. However, it may take a long time before charging completes depending on the usage of the speaker. It is recommended that you turn off the speaker before battery charging. You can charge the speaker's built-in battery by connecting the speaker to a computer that comes equipped with a USB charging port as well. However, not all the computers are tested and found compatible with this procedure and the procedure is not applicable to home-built computers. Do not connect the speaker to a computer for a long period of time when the computer is not connected to an AC power supply. Otherwise, the computer's battery may run out. 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 USB cable from the speaker and connect it again within an operating temperature between 5 °C and 35 °C (41 °F and 95 °F). At high temperature, the charging may stop or the volume may reduce to protect the battery. Charging from a USB hub is only guaranteed when you use a self-powered USB hub that carries an authorized logo. While the speaker is connected with a computer that is not connected to an AC outlet, the speaker consumes the battery power of the computer. Do not leave the computer with the speaker connected for a long period of time to prevent the computer's battery from running out of power.
