Can You Bring a Power Bank on Southwest Airlines?
Yes, Southwest Airlines allows portable power banks in carry-on bags. They are considered personal electronic devices with batteries and must be packed in your cabin luggage, not checked baggage. This rule follows U.S. Department of Transportation guidance for lithium batteries.
Power Bank Size and Watt-Hour Limits
Southwest follows FAA rules for lithium batteries. Power banks up to 100 watt-hours are allowed without airline approval. A typical 20,000 mAh power bank is usually around 74 watt-hours and fits this limit. For batteries between 100 and 160 watt-hours, you need Southwest’s approval. Each passenger can generally carry up to two spare batteries above 100 watt-hours with prior permission.
Charging and In-Flight Use Tips
Most Southwest aircraft have limited power outlets, often found in select rows or business class seats. You can charge your power bank during the flight, but using it while the plane is taxiing, taking off, or landing is not allowed. Southwest recommends keeping devices stowed during these times and following crew instructions.
