Flying with a CPAP Battery on Southwest Airlines
Southwest Airlines travel guidance for EXP PRO customers. Southwest’s current published power bank policy is stricter than the general 101–160Wh FAA allowance, so EXP48PRO travelers should confirm directly with Southwest before flying.
EXP48PRO: 154Wh
Southwest Power Bank Limit: 100Wh
Carry-On Only
Confirm Before Travel
Quick Answer
The EXP48PRO is a 154Wh CPAP battery. Southwest’s current published power bank / portable charger policy says power banks must not exceed 100Wh. Because the EXP48PRO is over 100Wh, customers should not assume it will be accepted on Southwest flights unless Southwest confirms in writing that it may be carried as a CPAP battery for that specific itinerary.
154Wh
Over Southwest’s 100Wh power bank limit
Do not assume acceptance without written Southwest confirmation.
Important Southwest Airlines Notice
Southwest’s current published policy for power banks / portable chargers limits them to 100Wh or less. The EXP48PRO is 154Wh. While the EXP48PRO is designed as a CPAP battery and falls under the broader 101–160Wh lithium battery category used by FAA guidance with airline approval, Southwest may apply its stricter 100Wh power bank policy. For this reason, EXP PRO recommends contacting Southwest directly before travel and requesting written confirmation.
