You can use any type-C usb cable to charge JBL Pulse 4. The recommended charging time for the speaker is 3 to 4 hours. There's an LED indicator showing the charging progress of the battery, once it's full it will turn off.
Sorry, there was a problem. Please try again later.Press any button on there an a white light will shine and tell how charged it is and next to it is a slot to charge your speaker.
