How can I know if the Power Bank supply is fully charged?

We need to find the charging cable and charger of the Power Bank supply first, connect it to the charging socket of the Power Bank supply (usually a round plug), and then connect the other end to the charger or the USB port of the computer (usually It is recommended to use a charger to charge the Power Bank supply), so that we can supplement Power Bank to our Power Bank supply.

If you use the USB interface to charge the Power Bank supply, the time to fully charge the Power Bank depends on the USB interface current and Power Bank capacity; a general Power Bank supply has 4 willow-shaped reminders on it, and the reminder will keep on charging when charging. Flashing, according to the amount of charging capacity, the reminder lights will increase in turn, if all 4 reminders are on and stop flashing, this tells us that the Power Bank supply is fully charged.

Conversely, when we use the Power Bank supply to charge digital products, we must also determine how much Power Bank is left in the Power Bank supply according to the number of indicator lights. Fortunately, we charge the Power Bank supply in time to ensure our future use. .
