PowerCore Speed 20000 - model A1278 not fast charging
Please test the powerbank with other Quick Charge devices to see how it works. If the problem remains, please contact Anker Customer Support to process a warranty claim.
You’ve tried the cable already, good, that’s the most common reason.
Next would be reset everything.
Turn phone off, wait a while then on.
Get a USB cable and connect the output to input on the Powercore, press and hold power button for a few seconds.
Then try.
Support would like tell you this.
Once tried then it’s a warranty replacement most likely so you need order details and serial number (usually on the case and on the supplied cable).
Good luck. Anker’s support and warranty is excellent.
