    It’s very good charger. It got my phone to charge from 5% to about 70% but I didn’t charge it until the portable charger died so it still had more juice.

    It works like it should but it is a bit heavy to carry around in a pocket or something. I was able to fully charge my note 9 three times with 25% battery left. It is a good idea to have this battery pack on hand.
