Portable Batteries on Airplanes: New Safety Rules in 2026
Portable Batteries on Airplanes: Lithium-ion batteries power nearly every device we rely on today — from smartphones and tablets to laptops and portable chargers.
Their convenience is unmatched, with fast charging, compact design, and long battery life.
However, these benefits come with a rare but real risk: under certain conditions, Li-ion batteries can ignite or explode, particularly in confined spaces like airplanes.
Why Airline Regulations Are Evolving
Over the years, multiple incidents involving battery fires on passenger aircraft have prompted airlines and regulators worldwide to update safety protocols.
While carrying your laptop or phone may feel routine, it’s crucial to understand that portable batteries on airplanes are strictly regulated, especially when it comes to checked luggage.
Globally, passengers are prohibited from placing spare lithium-ion batteries or power banks in checked baggage.
Rules regarding what you can bring onboard vary by airline, which is why confirming regulations before your flight is essential.
Some carriers also restrict using or charging portable batteries during flights, so planning ahead prevents last-minute issues at the gate.
High-Profile Incidents Prompting Stricter Guidelines
In early 2025, a flight from South Korea to Hong Kong experienced a power bank fire in the overhead compartment, forcing an emergency evacuation.
Such incidents, though rare, highlight the potential hazards of lithium-ion batteries at high altitudes.
Following this event, many airlines, including Thai Airways, Singapore Airlines, and several U.S. carriers, implemented stricter policies on the storage and use of portable batteries on airplanes.
Understanding the Risk: Thermal Runaway
The main danger with lithium-ion batteries is thermal runaway — a rapid, self-sustaining reaction that can lead to fire.
A short circuit or damaged battery cell generates extreme heat, which can trigger neighboring cells to ignite. In seconds, temperatures can exceed 900°F (500°C), creating sparks capable of igniting nearby materials.
While rare, the consequences in a confined airplane cabin can be severe, making adherence to regulations critical.
Carrying batteries in the cabin instead of checked luggage allows crew members to quickly respond to any incidents.
Traveling Safely with Portable Batteries
Here are essential guidelines for flying with portable batteries in 2026:
-
Carry-On Only: Always place spare batteries and power banks in your carry-on bag. Checked luggage is off-limits.
-
Check Battery Capacity: Airlines follow FAA Packsafe rules:
-
Up to 100Wh: Allowed
-
101–160Wh: Allowed with airline approval
-
Over 160Wh: Prohibited
-
-
Seek Airline Approval: High-capacity batteries require pre-approval.
-
Protect Terminals: Cover exposed contacts to prevent short circuits.
-
Inspect Batteries: Avoid using swollen, dented, or damaged batteries.
-
Purchase Reputable Brands: Quality significantly reduces the risk of malfunction or thermal runaway.
