TROUBLESHOOTING

11

Problem

When the device is connected to DC output of the power 

bank for charging, the power bank (Jump starter) 

automa�cally turns off a�er few seconds.

The device ra�ng is less than 500 mA, so the power bank 

cannot read the input device and turns off automa�cally. 

The minimum ra�ng for a device to be charged is 500 mA.
