Why is my power bank providing fewer charges than expected?

A power bank loses 30%-45% energy as heat during charging due to cable resistance and internal circuitry. A fully charged 20000mAh bank provides about 11000mAh-14000mAh to devices.

Can we travel by plane with this power bank?

Our power bank complies with TSA (Transportation Security Administration) regulations for onboard transportation.
