There are certain rules covering Power banks. Generally, Batteries with a capacity of up to 100 W are allowed while boarding the plane. These are prohibited on planes from being carried check in baggage. You can carry them in the carry on bags.
In fact, the rules specifying the guidelines are carried out as long as batteries and power banks are quite ambiguous. And this causes a lot of confusion. There have been a few cases in recent times wherein passengers have been asked to collect the power bank and such items from the airport authority in 14 days. They were not allowed to carry it in either their carry-on bag or check-in bag.
As per the rules, the power banks are allowed in carry-on bags, while prohibited in check in bags, but exactly opposite is the case with the dry cell batteries. These batteries are allowed in check in bags, but cannot be carried in the cabin.
