The SRS-XB100 can be charged via the USB-C port. Please use a commercially available USB power adapter with an output power of 5 V / at least 0.5 A. For optimum charging results, we recommend a power supply unit with 5 V / 1.5 A or higher. The full charging time is approx. 4.5 hours. You can also charge the built-in the speaker's built-in battery by connecting the USB cable connected to the speaker to a computer that is also that is also equipped with a USB charging port. However, not all computers can be tested and found to be compatible with this method, and the method is not applicable to home-built computers. Please make sure to close the port tightly after charging to maintain water and dust tightness. You can find more information on our support page.
hello, the speaker has a usb-c connection and is supplied with a cable (usb-c/usb-a) without a mains plug. therefore the speaker can be charged with the supplied cable at any usb-a connection (in the car, on the computer, via adapter), works perfectly.
