Actually, airlines do not allow power banks in the cargo luggage for the purpose of safety. Power banks are essentially batteries that utilise lithium cells. Lithium batteries have a tendency to combust, and are therefore prohibited for cargo transport, as part of air-transport regulations.
While not all batteries are prohibited in checked luggage, lithium batteries are considered hazardous and should not be packed in checked bags. If a lithium battery overheats and catches fire inside the cargo hold, the fire can quickly spread and become difficult to control.

Chargers and cables for electronic devices don't need to be removed from your carry-on when going through airport security. That said, they do clutter the x-ray images a lot, so unless you've packed just a few chargers in there, the TSA agents might ask you to remove them from the bag and place them in a separate bin.
For example, TSA guidance is very clear: If prohibited items are found during security checks, they won't be returned to their owners. That may vary in other countries, but the general rule is that confiscations are permanent.
Remove personal electronic devices larger than a cell phone from your carry-on bag and place them into a bin with nothing placed on or under them for X-ray screening. (E.g. laptops, tablets, e-readers and handheld game consoles.) Remember to check the bins and collect all belongings after going through screening.
