Flynn, most recently chief fire marshal, will oversee day-to-day FDNY operations across bureaus and offices. He was appointed to the FDNY in 2005, rose through Ladder Company 114 to fire marshal leadership and has led the Bureau of Fire Investigation since April 2021. The department credited Flynn with shaping its response to lithium-ion battery hazards and pushing legislation to curb unregulated batteries.
That quick check wasn't random. In response to safety concerns surrounding lithium-ion batteries, the TSA has stepped up enforcement and is paying closer attention to power banks during security screenings. "TSA has not 'banned' power banks. However, they are only allowed in carry-on bags," a spokesperson told Travel + Leisure. Most standard power banks fall under the FAA's 100Wh (or 27,000mAh) limit, but higher-capacity models are increasingly common, especially among travelers looking to charge laptops or multiple devices.
