Power Bank Restrictions on Flights 2026: ICAO Lithium Battery Rules Explained—2 Max, 100Wh Free, No In-Flight Charging

Starting March 2026, the International Civil Aviation Organization (ICAO) has implemented strict new rules on power banks for all commercial flights worldwide—and millions of daily travelers must now verify their devices comply or leave them behind.

What Triggered the Change

The ICAO, the United Nations agency governing international civil aviation, rolled out these revised lithium-battery guidelines after a series of cargo-hold fire incidents linked to faulty power bank batteries. Lithium-ion cells can undergo thermal runaway—a chain reaction causing fires—if damaged, overcharged, or exposed to extreme heat in the confined, pressurized environment of an aircraft cabin.

Aviation safety experts have consistently flagged the risk as passenger reliance on mobile devices surges globally. These regulations represent a proactive shift: rather than react to incidents, ICAO is preventing them by controlling how and where power banks travel.

Airlines and Airports Affected

Every commercial airline and airport worldwide must enforce ICAO's baseline standards, though several carriers and national aviation authorities have adopted even stricter measures. Southwest Airlines, American Airlines, and Singapore's aviation authority now limit passengers to one power bank or require explicit pre-flight approval for devices in the 100–160 watt-hour range. South Korea implemented the two-unit rule ahead of the official March 2026 deadline.

Power Bank Capacity	Carry-On Permission	Checked Baggage	Airline Approval Required
Up to 100 Wh	Yes (2 max per person)	Prohibited	No
100–160 Wh	Yes (2 max per person)	Prohibited	Yes
Over 160 Wh	Prohibited	Prohibited	N/A

What Travelers Get

• Maximum two power banks per person allowed in carry-on luggage only; checked baggage is strictly prohibited.
• Power banks up to 100 watt-hours (Wh) can be carried freely without airline pre-approval.
• Power banks between 100–160 Wh require explicit written approval from your airline before boarding.
• Power banks exceeding 160 Wh are completely banned from all flights.
• No in-flight charging permitted: passengers cannot charge power banks using onboard outlets, nor can they use power banks to recharge phones, tablets, or laptops during flight.

What This Means for Travelers

Pack your power banks in easily accessible carry-on locations—under your seat or in the seat pocket—so crew can reach them quickly in an emergency. Before traveling, check your device's watt-hour rating (printed on the label or battery casing); if it falls between 100–160 Wh, contact your airline at least 48 hours before departure to request approval. Expect longer security screening times as airport staff inspect power banks more thoroughly. If you rely on mid-flight charging, plan to fully charge devices before boarding or bring a second fully charged power bank instead. Visit the ICAO official website and your airline's safety guidelines page for the most current rules, as some carriers enforce stricter limits than ICAO's baseline.

FAQ: Power Bank Restrictions on Flights 2026

Q: Can I charge my phone using a power bank during a flight? No. The new ICAO regulations prohibit using power banks to charge any device onboard. Charge all devices before boarding.

Q: What happens if my power bank exceeds 160 Wh? It is completely prohibited on all commercial flights. You must leave it behind or ship it separately via ground transport.

Q: Do I need airline approval for a 100 Wh power bank? No. Power banks up to 100 Wh are permitted freely. Only devices between 100–160 Wh require pre-flight airline approval.
