Please check the output of the battery and confirm if your phone accepts the power accordingly:
USB output: 5V/1A
Type-C output: 5V/2.5A (max)
QC3.0 output (the blue port): 5V/2.4A; 9V/1.5A; 12V/1.35A
Kindly note the ToughJuice will shut up charging automatically when the charging output is less than 200mAh, which means the battery can't charge a Bluetooth earphone.
