The power bank seemed unstable, meaning for the first several seconds it worked but afterwards it stopped working unless re-plugging the cable, and every time it was like this. I had to test it to see if it was working so I just wonder if there is damage to the battery or the Tristar/U2 chip (power IC) for what I did.
Thanks in advance.
