The input of this power bank is 5V/2A, you can check the output of the port on your auto battery. You can press the button on the power bank, the remaining power of the LED indicators will light steadily; while the next charging LED indicator will flash. And they will turn off in 10min±2min after the powercore is fully charged. If you have any further questions, please feel free to contact us via [email protected] or call us at +1 (800) 988 7973.
