Power Bank Ban: Why are power banks banned on flights? Is it for passenger safety or is there some other reason?

Emirates Airlines has banned the use of power banks on flights. This decision has surprised everyone, as many passengers carry power banks on flights to charge their phones and other gadgets. This decision has come as a shock to those who travel with Emirates Airlines. Let's find out why this decision was taken. Is it for passenger safety or is there some other reason?
Under Emirates' new policy, passengers can now carry only one power bank with them, but it must be less than 100 watts (Wh). The power bank must clearly state its capacity. You can carry a power bank, but cannot use it on a flight.
Why was this drastic decision taken?
The ban on power banks is primarily a safety concern. Power banks use lithium-ion or lithium-polymer batteries, which can overheat and even catch fire. This is due to a process called thermal runaway, in which the battery's temperature rises, potentially leading to a fire or explosion.
This decision has been made to reduce the risks associated with batteries on aircraft, especially with low-cost power banks that lack safety features like automatic shut-off. Emirates Airlines has taken this decision for your safety. Passengers traveling with Emirates Airlines should now fully charge their phones and other gadgets before leaving home for the airport.
