Unable to charge the speaker
- When using a USB AC adaptor (commercially available), make sure the micro-USB cable is firmly connected to the speaker and the USB AC adaptor. In addition, make sure the USB AC adaptor is firmly connected to an AC outlet.
- When using a USB AC adaptor (commercially available), make sure the USB AC adaptor has the ability to output in 1.5 A or more. Charging from a USB AC adaptor which has the ability to output in 500 mA or more and less than 1.5 A takes about 10 hours. Charging from a USB AC adaptor which has the ability to output in less than 500 mA is not guaranteed.
- The estimated charging time differs depending on the power output capacity of the connected USB AC adaptor (commercially available). The speaker supports a USB AC adaptor with an output current of 500 mA or more. However, depending on the type and specification of the USB AC adaptor and micro-USB cable, the charging time may take a long time. Using a USB AC adaptor with an output current of 1.5 A or more and a supplied micro-USB cable or micro-USB cable conforming to the USB standard is recommended. Charging from the other device is not guaranteed. The charging time may vary depending on the ambient temperature or conditions of use.
- You can also charge the built-in battery by connecting it to a booted computer via the micro-USB cable. However, operation with all computers is not guaranteed. Operation with a home-built computer is also not covered by the warranty.
