How did power banks cause diversions?

Faulty portable chargers have triggered in-flight diversions

Aviation regulators have warned travelers about portable power banks after a rise in flight diversions linked to faulty devices. The core issue is safety: malfunctioning lithium batteries can overheat, and that risk escalates when power banks are packed or handled in ways that allow damage, shorting, or overheating.

Airlines and aviation authorities are emphasizing that travelers must store and transport these devices carefully. The practical reason diversions happen is that an inflight technical concern related to a charger or battery can require immediate crew attention and, depending on severity, lead to a change of plan to protect passengers.

What passengers can do

• Carry power banks in line with airline rules (many policies prioritize carry-on access so the device can be managed quickly if there’s an issue).
• Prevent terminal contact with metal objects by using cases/covers or keeping them secured.
• Avoid physical stress (don’t pack them loosely where they can be crushed by heavier items).
• Don’t travel with visibly damaged batteries.

Planning impact

These events matter because they can be disruptive even when travelers did everything they could to comply with normal packing expectations. If you’re traveling with multiple chargers—especially along with other tech like cables and hubs—pack them in a dedicated pouch so they remain protected and reduce the chance of an incident.

The broader message is straightforward: power banks are small, but regulators are treating them as a real safety priority this travel season, and recent diversions underscore why.
