As the power bank charges usually one LED light blinks, the last one in the series. For example, if there are 3 LEDs on, then only the 3rd one will blink until the next charging level is reached and then the 4th LED will start blinking. Once the power bank has reached a 100% charge level, all the LED lights will be constantly on, without any one of them blinking, until you unplug the device from the charger. And as you start charging another device using your power bank, the LED blinking pattern will resume designating the transfer of electricity. Some of them supply more power and thus can charge a power bank faster, while others are slower and they can add several hours to the charging time of your device.
