If the Charge 4 is used a power bank while it’s coupled on a charging pad, will both devices be charged up?
If the Charge 4 is used as a power bank while it’s coupled on a charging pad, will both devices be charged up?
The JBL Charge 4 Quick Start Guide indicates that the device can function as a power bank to charge other devices and can also be charged itself. However, the manual explicitly states: "DO NOT EXPOSE JBL CHARGE 4 TO WATER WHILE CHARGING. IT MAY RESULT IN PERMANENT DAMAGE TO THE SPEAKER OR POWER SOURCE." While this warning specifically mentions water, it implies that charging the JBL Charge 4 while it is simultaneously providing power to another device (acting as a power bank) is not recommended and could potentially lead to damage or inefficient charging for both devices. The manual does not provide instructions for using it as a power bank while it is being charged on a charging pad, suggesting this is not a supported or recommended use case.
