@dzynwa7, Thanks for your question and effort to test. @cava3395 ,thanks for your right answer about the indicator. If the PowerCore + 20100 USB-C is fully recharged, all the indicators would turn solid and will turn off automatically later.
Please kindly be noted that the PowerCore + 20100 USB-C usually takes 8-9 hours for a full recharge via a 5V/2.4A power supply. There should be no problem to recharge it via an iPad wall charger(which offers 5V/2A output) with the A-C cable comes with our battery.
To verify the issue further, could you please kindly try recharging the PowerCore + 20100 USB-C via another 5V/2A or 5V/2.4A wall charger(such as a Samsung adapter) with another A-C cable to double check whether the last indicator still flashes? Also, may we know how many times of charge could your PowerCore + 20100 USB-C offer to your phone(please let us know the model) after a long time recharge(with the last indicator flashs)?
Could you please contact us Anker at "email@example.com" with above test result? Please be assured that we offer 18 months warranty(replace or refund) and lifetime technical support. If the problem is with the Anker battery and it is within our warranty coverage, we are glad to arrange a replacement to you for a try.
Hope to hear from you soon.
