Southwest Airlines' New Carry-On Portable Charger Limits

Southwest Airlines has implemented specific limitations on the size and capacity of portable chargers allowed in carry-on baggage. Understanding these limits is key to avoiding problems at the security checkpoint.

• Maximum power bank capacity: The maximum permitted power bank capacity is typically capped at 100 watt-hours (Wh). While Southwest doesn't explicitly state a mAh limit, remember that Wh is calculated by multiplying voltage (V) and capacity in milliampere-hours (mAh) and dividing by 1000 (Wh = (V x mAh) / 1000). Therefore, knowing your power bank's voltage is essential to determine if it's within the limit. A higher voltage battery will reach the 100Wh limit with fewer mAh.
• Specific dimensions: While Southwest doesn't specify exact dimensions, it's advisable to keep your portable charger relatively compact to avoid potential issues. Larger power banks may be flagged for additional screening.
• Number of portable chargers: Currently, Southwest allows a reasonable number of portable chargers per passenger, typically one or two, as long as they meet the capacity requirements. Always check the latest updates on their website for the most current allowance.
• Consequences of exceeding the limits: Exceeding the allowed capacity or dimensions may result in the confiscation of your portable charger. In some cases, this might also lead to delays and potential fines.

Understanding the FAA Regulations and Southwest's Compliance

Southwest Airlines' portable charger policy aligns with Federal Aviation Administration (FAA) regulations on lithium-ion batteries. These regulations prioritize safety by limiting the energy density of batteries carried on board aircraft.

• Relevant FAA regulations: The FAA's guidelines for lithium-ion batteries focus on preventing fires and explosions. They specify limits on battery capacity and require proper packaging.
• Southwest's interpretation: Southwest generally adheres to FAA guidelines. However, it's crucial to consult their official website for the most up-to-date and specific interpretation of these regulations, as interpretations can differ slightly between airlines.
• Discrepancies with other airlines: While many airlines follow similar guidelines, slight variations may exist in their specific policies regarding portable charger limitations. Always check the specific rules of the airline you are flying with.

Packing Your Portable Charger Safely for a Southwest Flight

Proper packing of your portable charger is essential to comply with safety regulations and ensure a hassle-free travel experience.

• Recommended packaging: Keep your portable charger in its original packaging whenever possible. If not, use a protective case to prevent damage during travel.
• Easy access: Place your charger in a readily accessible location in your carry-on bag for easy access during security checks. This will expedite the screening process.
• Avoid damaged chargers: Do not carry damaged or recalled portable chargers. These present an increased risk of malfunction and should be replaced before travel.

What to Do if Your Portable Charger Exceeds the Limits

If your portable charger doesn't meet Southwest's requirements, several options are available:

• Shipping separately: Consider shipping your power bank separately via a courier service. This ensures its safe arrival at your destination without causing delays at the airport.
• In-flight power outlets: Many Southwest aircraft have in-flight power outlets. This might allow you to charge your devices directly on the plane, negating the need for a large portable charger.
• Purchasing a compliant charger: Consider purchasing a smaller, compliant portable charger before your flight to avoid any potential problems.

Staying Updated on Southwest Airlines' Baggage Policies

To avoid any surprises, stay informed about Southwest Airlines' baggage policies.

• Official website: Regularly check the official Southwest Airlines website for the most current updates on their baggage allowance and carry-on regulations. This is your primary source for accurate information.
• Email alerts: Sign up for email alerts or notifications from Southwest Airlines to receive updates on policy changes.
• Social media: Monitor their social media accounts (if they offer updates there) for announcements regarding baggage policy changes.

Conclusion:

Southwest Airlines' updated carry-on portable charger policy emphasizes safety and compliance with FAA regulations. Remember the key restrictions: a maximum of 100 Wh (with the understanding that the mAh will depend on voltage), proper packaging, and adhering to the airline's guidelines on the number of chargers permitted per passenger. Failing to comply can lead to delays and confiscation of your device. Before your next flight, review the official Southwest Airlines website for the most up-to-date information on their carry-on portable charger policy and baggage allowances for other items to ensure a smooth and hassle-free travel experience.
