Flying with a CPAP Battery on Southwest
Southwest Airlines travel guide for the EXP48PRO CPAP battery. Learn how the 154Wh EXP48PRO fits the 101–160Wh lithium battery travel category and what to prepare before you fly.
Quick Answer
The EXP48PRO is a 154Wh CPAP battery, which places it under the 160Wh maximum used in FAA lithium battery guidance for larger spare lithium-ion batteries. Because Southwest has specific rules for spare batteries and portable chargers/power banks, customers should confirm approval with Southwest before travel and keep the EXP48PRO in carry-on baggage or on their person.
