Hello, generally speaking, Anker charging treasure will light up when it clicks the green light. At this time, you can observe the green light state to judge the remaining power of the charging treasure. If the green light is steady on, the power of the charger bank is sufficient. If the green light blinks, the power of the charger bank is low. In addition, Anker charging bank also has a variety of protection functions, such as overcurrent protection, short circuit protection, overvoltage protection, etc., which can effectively extend the service life of the charging bank. It should be noted that in order to improve battery life, the charging bank may set the sleep mode, and you need to press the power button to start the charging, otherwise it may not be able to charge normally or the charging is interrupted. In short, click the green light to observe the power level, but you need to pay attention to other working states of the charging bank.
If you press the power bank twice, it will be a green light display, telling you how much power is left in the current power supply.
