I guess it depends on the peak current your power bank can supply. The 10000maH is the capacity of power bank.
For normal operation, a power bank with 2.4A output current should be sufficient. Yet, if there is a sudden surge of power demand due to high processing needs, the power bank might not be in time to provides the power needed, voltage might drops and the Raspberry Pi might restart.
