I purchased this power bank since I want to use my matrix creator in a portable setup.

When I use 2.5A supply power adapter, nothing will happen when startup (normal); on the other hand, when I use the portable power bank (2A supply), random LEDs will turn on for 1~3 seconds and then turn off.
Although all other functionalities seems fine, I am afraid that I might damage the board. Any plausible explanation why there is a difference in startup behavior between using portable power bank and power adapter (wall plug)?
