Southwest Airlines Tightens Portable Charger Limits Amid Safety Concerns
Southwest Airlines Tightens Portable Charger Limits Amid Safety Concerns...
Southwest Airlines has quietly updated its policy on portable chargers, reducing the allowed watt-hour capacity from 160Wh to 100Wh for carry-on luggage. The change, implemented this week, follows recent FAA warnings about lithium-ion battery fires during flights. Passengers are reporting confusion at TSA checkpoints where the new rules are being enforced inconsistently.
The policy shift comes after a March 2026 incident where a smoking power bank forced an emergency landing in Phoenix. Aviation safety expert Dr. Lisa Yang confirms this aligns with growing industry concerns: "We're seeing more near-misses from cheaply manufactured chargers overheating at altitude."
Frequent flyers are particularly affected, as many premium portable chargers exceed the new limit. Business traveler Mark Reynolds told us: "My $200 Anker battery just became carry-on contraband overnight." Southwest's website now specifies that any charger over 100Wh must be shipped as cargo.
The airline hasn't issued a formal press release, but gate agents began enforcing the policy April 10. Social media shows TSA agents at Dallas Love Field turning away passengers with larger power banks. A Southwest spokesperson confirmed this is a permanent change, not temporary like their 2025 holiday season restrictions.
Consumer advocates warn the policy could strand travelers with dead devices. "Airports still don't have enough charging stations," notes Travelers United president Charles Leocha. The DOT reports 37% of US flights still lack seat power ports, making portable chargers essential for many passengers.
Industry analysts suggest other airlines may follow suit. American and Delta currently allow up to 160Wh batteries, but both carriers told us they're "continually evaluating safety protocols." The FAA is expected to issue updated battery guidelines this summer after completing fire containment tests on newer charger models.
Passengers should check their charger's watt-hour rating (usually printed in small type) before flying Southwest. The airline recommends using their Bag Check Calculator tool for uncertain cases. Those caught with prohibited chargers will need to surrender them or miss their flight - no compensation is offered for confiscated devices.
