Understanding Southwest's New Carry-On Policy for Portable Chargers

Southwest's updated carry-on policy for portable chargers aims to enhance flight safety. The airline now has specific size and power capacity restrictions for portable chargers allowed onboard. These restrictions align with industry best practices and Federal Aviation Administration (FAA) regulations concerning lithium-ion batteries. Let's break down the specifics:

• Specific wattage limits for portable chargers: Southwest currently allows portable chargers with a maximum wattage of 100Wh (watt-hours). Chargers exceeding this limit are generally prohibited from carry-on baggage. Always check the wattage rating printed on your portable charger.
• Dimensions allowed for carry-on portable chargers: While there aren't explicitly stated dimensional limits, it's advisable to ensure your portable charger fits comfortably within your carry-on bag and doesn't present a safety hazard due to its size or shape. Avoid overly large or oddly shaped power banks.
• Whether external batteries are included in the updated policy: Yes, the updated policy specifically addresses external batteries, commonly referred to as power banks, falling under the same wattage and safety guidelines.
• Clarification on the number of portable chargers allowed per passenger: Southwest typically allows a reasonable number of portable chargers per passenger, as long as each device meets the specified wattage limit and overall carry-on baggage restrictions are adhered to. Contact Southwest directly for clarification if you plan to carry multiple devices.

Why Southwest Changed its Portable Charger Policy

The driving force behind Southwest's updated policy is the inherent safety concerns associated with lithium-ion batteries. These batteries, while powering our devices, pose potential risks if improperly handled or damaged, especially in the confined environment of an aircraft cabin.

• Specific safety concerns related to lithium-ion batteries in aircraft cabins: Lithium-ion batteries can overheat, causing fires or explosions under certain conditions. These risks are amplified in an aircraft cabin due to pressure and temperature fluctuations during flight.
• Reference any relevant FAA or other regulatory body guidelines: Southwest's new policy aligns with evolving FAA regulations and industry best practices aimed at mitigating the risks associated with lithium-ion batteries in air travel. These regulations are frequently updated to reflect advances in battery technology and safety research.
• Explain any potential risks associated with larger or higher-capacity portable chargers: Larger and higher-capacity portable chargers carry a proportionally higher risk of overheating and potential incidents. The wattage limits imposed by Southwest directly address this risk.

Packing Your Portable Chargers for Southwest Flights

Properly packing your portable charger is just as important as understanding the regulations. Following these simple steps ensures both safety and compliance:

• Recommendations on carrying cases or protective sleeves: To prevent damage and accidental activation, consider carrying your portable charger in a protective case or sleeve. This adds an extra layer of security and prevents accidental short circuits.
• Advice on keeping chargers separate from other electronic devices: Keep your portable charger separate from other electronic devices and other metal objects to reduce the risk of short circuits or accidental damage.
• Tips for avoiding potential damage to the charger during transit: Avoid placing heavy items on top of your portable charger in your carry-on luggage. Gentle handling helps prevent internal damage that might trigger overheating.
• Suggestions for charging devices before boarding the flight: Charge your devices fully before boarding the flight to minimize the need for extensive usage of your portable charger during the flight.

What Happens if Your Portable Charger Doesn't Comply?

If your portable charger exceeds the allowed wattage or otherwise violates Southwest's carry-on rules, it may be confiscated at the security checkpoint. While you won't necessarily face hefty fines, you will lose the device. There may also be delays in your boarding process. For extremely large or suspect devices, further investigations may be undertaken by airport security. In short, it's best to avoid this situation entirely by ensuring your portable charger complies with the regulations before you arrive at the airport.

Conclusion

Southwest's updated carry-on rules for portable chargers emphasize the importance of passenger safety. Understanding the new wattage limits and packing guidelines is essential for a seamless travel experience.
