It might be a good idea to start charging your phone before you travel—airlines around the world are now tightening their rules surrounding portable chargers and power banks.If you're traveling via Southwest Airlines in the future, you’ll need to keep your portable charger visible anytime you're using it, which means no leaving your phone to charge in your baggage or the overhead storage compartment. The airline stopped short of a full ban, however, and you can still bring up to 20 spare batteries on your next Southwest flight. You are also still allowed to store these in your hand luggage, just not use them. Meanwhile, storing the lithium-based batteries most portable chargers use in checked luggage has been banned in almost all countries since 2021. Though Southwest is the first major US airline to introduce these types of rules, it's certainly not alone internationally. Airlines like Malaysia's AirAsia announced similar restrictions on portable chargers on April 1, while Thailand’s Thai Airways has also introduced comparable rules in recent months.Recommended by Our EditorsThe spate of new restrictions comes after an airplane fire in Busan, South Korea, earlier this year. The true cause of the incident is still unknown, though investigators suspect it may have been due to a malfunctioning lithium-ion battery. These types of batteries, although generally safe, can be highly combustible under specific circumstances, like extreme overheating or manufacturing defects. A Southwest spokesperson told The New York Times that the new rules will help its flight attendants react quicker in the event of battery fire, citing “multiple incident reports” involving batteries on its flights. Though the rules could be inconvenient for some, Southwest passengers simply aren’t going to be forced to accept dead batteries anytime soon. As of 2023, Southwest began introducing USB charging ports on all of its planes, meaning you should be able to get by with just a simple USB cable in a pinch, rather than needing a charging bank.  #charge #your #phone #southwest #airlines
