Power bank use on Emirates flights is no longer allowed, with the airline siting the increase use of portable charges and the risk of “thermal runaway”. “Using any kind of power bank is prohibited onboard Emirates’ flights, effective from 1 October 2025,” the airline said in a statement. “A power bank is a portable, rechargeable device primarily designed to provide power to other electronic devices such smart phones, tablets, laptops and cameras. “If in checked baggage the lithium battery or lithium power bank must be removed from the bag. The removed lithium battery or power bank must be in carry-on baggage only.
