Airlines are tightening in-cabin rules on power banks, with Europe’s Lufthansa Group and several Asia-Pacific carriers enforcing bans or strict limits starting in January 2026, reflecting a growing global safety trend. The shift is less about what you can pack and more about what you can do onboard. Use, charging, and where you store a power bank have become the new flashpoints.
A “power bank” is a portable battery pack, usually powered by lithium batteries, designed to recharge phones, laptops, and tablets. Airlines treat these differently from batteries installed inside devices.
A phone battery is built into a tested product with protective circuitry and a hard shell. A power bank is a spare energy source that gets handled, tossed in bags, and sometimes bought cheaply with unclear quality controls. That difference drives stricter cabin rules.
Restrictions usually show up in four ways. First, limits on how many power banks a person can carry.
Second, maximum battery capacity measured in watt-hours (Wh). Third, bans on charging a power bank from the aircraft’s USB or seat outlet. Fourth, bans on using a power bank to charge your devices during the flight.
Storage rules have also tightened, often requiring power banks to stay within reach rather than in overhead bins. Digital nomads and frequent flyers feel these changes fast.
Multi-device travel is common, and long-haul trips and tight connections push people to rely on onboard power. When airlines add power bank bans or stop onboard charging, you may need a different plan for keeping work gear alive between airports.
Current global implementation by region
Across Asia-Pacific, carriers have been moving from “recommended” behavior to explicit in-flight bans and handling requirements. Eastar Jet introduced restrictions as early as October 2025.
Jeju Air followed with rules starting January 22, 2026. A larger step arrives with Korean Air and other carriers under the Hanjin Group, with a cabin ban on use and charging beginning January 26, 2026.
Europe is taking a slightly different route, with formal limits paired with strict onboard behavior rules. Lufthansa Group rules took effect January 15, 2026, and they include both capacity limits and a clear prohibition on onboard use and charging.
SWISS applies the same approach as part of the Lufthansa Group framework. Effective dates matter in a simple way: the policy is tied to the flight date, not when you bought the ticket.
A booking made months ago can still fall under new rules if your travel date is after the effective date. Codeshares add another layer: a ticket sold by one airline may be operated by another, and the operating carrier’s onboard rules often control what happens at the gate and in the cabin.
Details of restrictions by major airlines
Airline policies tend to follow a few patterns, even when the wording differs. Quantity caps come first because power banks are treated like spare lithium batteries.
More spares mean more chances for damage, short-circuits, or overheating events. Capping the number per passenger also makes gate checks and cabin enforcement realistic.
Capacity rules come next, and they are usually expressed in watt-hours (Wh). Think of Wh as the “size” of the battery from an aviation safety point of view.
Many airlines draw a line at 100 watt-hours (Wh). Power banks in the 100–160 Wh (approval required) range may be allowed only with airline permission. Above that, they are typically not accepted for passenger carriage on many routes under common aviation practice.
Onboard behavior rules are where 2026 policies have tightened most visibly. Some airlines still allow you to carry a compliant power bank but forbid charging it from the aircraft’s power.
Others go further and prohibit using it to charge your phone in flight. That difference can surprise travelers, because “allowed onboard” no longer means “allowed to use.”
Storage rules are also changing. Several airlines want power banks kept within immediate reach, such as in a seat pocket or on your person, and not in overhead bins.
The logic is straightforward: if a battery overheats, a crew member can respond faster when it’s visible and accessible. An overhead bin hides early warning signs and slows response.
Medical-device exceptions exist in many policies, including cases where a power bank is needed to run or recharge essential medical equipment. Expect the airline to want details, and in some cases proof, before travel.
Each carrier controls how that exception is applied onboard.
| Airline Group / Carrier | Restriction Summary | Effective Date | Notes |
|---|---|---|---|
| Lufthansa Group | Max 2 power banks per passenger; max 100 watt-hours (Wh); 100–160 Wh (approval required); no use and no charging onboard; store under seat/seat pocket/on person; no overhead bins | January 15, 2026 | Medical-device exception applies for essential equipment. SWISS follows this framework. |
| SWISS | Same restriction set as Lufthansa Group, including no onboard use/charging and storage within reach | January 15, 2026 | Treated as part of Lufthansa Group policy alignment. |
| Korean Air | Use and charging prohibited in cabin; possession allowed with short-circuit prevention; keep within reach; no overhead bins | January 26, 2026 | Short-circuit prevention may include insulating tape or individual pouches. |
| Hanjin Group | Same cabin ban approach as Korean Air: no use, no charging; carry permitted with short-circuit protection and within-reach storage | January 26, 2026 | Applies across multiple Hanjin Group carriers. |
| Eastar Jet | Introduced restrictive approach aimed at reducing in-cabin risk from lithium batteries | October 2025 | Earlier move in Asia-Pacific toward explicit restrictions. |
| Jeju Air | Implemented tighter handling rules ahead of broader regional changes | January 22, 2026 | Part of wider Asia-Pacific push toward formal rules. |
Why the crackdown? Fire risk and safety considerations
Lithium batteries are efficient, but they can fail. A common failure pathway is overheating that escalates into thermal runaway, where heat triggers more heat in a chain reaction.
In a tight cabin environment, that matters. Several things can go wrong with a power bank: physical damage is one, manufacturing defects are another.
Counterfeit or low-quality packs add risk, especially if they lack basic protection features. Even a worn cable or debris in a bag can lead to a short-circuit at exposed terminals.
Airlines also restrict charging from seat power, or ban in-flight use, because charging adds heat. Using a power bank while it sits under a blanket or inside a stuffed bag can trap that heat.
Crew members have limited tools and limited time when smoke appears. Prevention is the goal.
“Immediate reach” rules address response time. If a device starts to smoke in a seat pocket, a passenger or crew member can act quickly. If the same event starts in an overhead bin, the warning signs can be missed until the situation grows.
✅ What travelers should do now: verify your flight’s power bank policy for your route, ensure any power banks are within the allowed Wh limit, and avoid charging onboard or using power banks during flight unless explicitly permitted
International safety standards and guidance
Airline crackdowns do not appear in a vacuum. International aviation practice already treats spare lithium batteries as carry-on items, not checked baggage items, because cabin crews can respond to problems more quickly.
Groups such as IATA and ICAO provide widely followed frameworks, while regulators such as the FAA and EASA shape expectations through safety guidance and enforcement culture.
Baseline guidance often permits passenger carriage of lithium batteries in carry-on bags with capacity-based limits, and it commonly uses Wh thresholds. Airlines can still go further; a carrier may decide that “carry is allowed” but “use is not.”
Checking the Wh label helps you stay compliant. Many power banks list Wh directly, while others show milliamp-hours (mAh) and voltage. In simple terms, Wh reflects capacity in a way airlines can compare across products.
If the Wh is not printed, look for manufacturer specifications on the device body or packaging before you fly.
Will this go global? Adoption trends and factors
Policy convergence is likely because airlines share the same basic problem: lithium batteries can fail, and in-flight response must be fast. Once major brands adopt strict rules, passenger expectations shift.
Gate agents also push for simpler enforcement, which favors clear bans on charging and clear storage rules. Divergence will persist, though, as national regulators can influence how strict airlines get.
Aircraft cabin layouts and seat-power systems also differ, and enforcement capacity matters too. Some carriers can staff gates for detailed checks, while others rely on broad, easy-to-explain rules.
Frequent travelers can stay resilient with one mindset: plan for no onboard charging. That means fewer power banks, clearly labeled capacity, and a willingness to keep batteries where you can see them.
Digital nomads should assume that a long-haul work plan that depends on mid-flight recharging may fail, especially on routes touching Asia-Pacific. Airline rules are changing on a calendar, not on your personal habits.
If you fly within Europe under Lufthansa Group rules already in force, or you fly with Korean Air or another Hanjin Group carrier on January 26, 2026 or later, pack and plan as if power bank use is off-limits in the cabin.
Airlines Adopt Power Bank Bans Over Lithium Batteries January 26, 2026
Global airlines are tightening restrictions on power banks beginning January 2026. New policies from Lufthansa, Korean Air, and others prohibit in-flight charging and usage. Carriers are enforcing capacity limits, usually at 100Wh, and requiring storage in accessible areas like seat pockets. These measures prioritize fire safety by ensuring crew can quickly respond to potential lithium battery failures or thermal runaway incidents during the flight.
