My anker 13000mAH charger (model 79AN7925) recently stopped charging my phone/devices consistently. I've noticed the indicator lights have been flashing abnormally as shown in the video i recorded below whenever the charger isn't actually providing power to my connected devices.
I tried draining the charger and re-charging it, and the charger itself charges up just fine and gets 4 solid lights, but it eventually does this weird flashing thing in the video and my devices dont charge.
I've also tried using different cables, but same issue.
Sometimes blowing into the usb ports temporarily "fixes" the issue and the lights stop blinking, and my device charges. But after a few minutes it stops charging and I notice the lights again.
Anyone have any idea what could be the issue? ive only been using this for about 2-3 years.
