How do I know that my Nako Power Bank is charging or is fully charged?

There are 2 power indicators on the Nako Power Bank. When plugged in with the provided usb cable to charge, the "Red" light indiciates that it is charging and the "Blue" light indicates that it is fully charged.

    Our chargers red light goes out while charging and never fully charges. Is it defective?

    Hi, my power bank was ok until yesterday when i put it to charge again and at first the red light was normal, but now is blinking ... and it appears that is not charging anymore because when i connect it to my phone it doesn't charge it either.

    What can I do? It is already broken? :( thanks for the answer.
