Hi everyone. I just bought a PowerCore+ 26800 PD and a PowerPort ll wall charger with PD as in my country I have to buy them separately.
The first thing I did was to charge the powerbank using the wall charger and the USB C-C cable provided by the powerbank. The initial powerbank provided me with 3 LED lights. So I went to charge overnight. The next morning, the powerbank was still charging so I figured the cable might be the problem as it was supposed to be fully charged by then. I unplugged it and it showed only 2 LED lights. It went down from 3 to 2 LED lights.
I did a second try by using another cable (USB C-C cable from Pixel 3 charging cable) to charge my powerbank using the same wall charger I bought. A separate issue occurred. This time, the powerbank was charging fine for less than 5 minutes then the LED wheel shut off. Meaning it was not charging.
I did a reset on the powerbank by looping a USB A-C on the powerbank. I had to try it again. This time, it was charging for some time. When I got back from outside, the LED wheel was not lit so I assumed the powerbank was fully charged. I was out for about half a day so the powerbank should be fully charged by then. I unplugged the powerbank and pressed the LED power button. It was all lit up (100%) but after awhile it went down to 3 LED lights when I decided to confirm it had been fully charged.
I had emailed the customer support and am waiting for their response.
What could be the issue here?
