Low battery alarm mode
When the product is used as a power bank, if the battery power is less than 15%, the battery power grid symbol will flash, which indicates that the battery power is insufficient, and need to charge in time.

Low voltage activation function
When the charger is in standby status, correctly put the low voltage battery (battery voltage ≤ 2.9V) to the charging channel, the charger's charging function will start, and then activate the low voltage battery automatically.
Due to the differences over the discharge times, capacity, over-discharge degree, the duration of low voltage and other factors of the low voltage battery, the activation time can be quite different. After the battery is activated, charging the battery according to the charging process.

Overcharge protection and automatic detection charge function
When the battery is full, the charger starts overcharge protection and stops charging automatically.
If not remove the battery for a long time after charging, the charger will consume a certain amount of battery power. When the battery voltage is lower than 4.0V, the charger restarts the charging function.
