Meta description: The 2026 global baseline for power banks on flights — quantity limits, in-flight charging ban, and why your specific airline can still be stricter.
Short answer
As a rule, since 27 March 2026 you can carry up to two power banks in your cabin baggage only (never checked), you cannot recharge a power bank during the flight, and each unit is capped by watt-hours — but individual airlines are free to apply stricter limits than this global baseline, so check your specific carrier’s policy before you pack.
If this is happening right now
- If security or crew has flagged your power bank, show the item’s printed watt-hour (Wh) rating — most banks list it on the casing — since that number, not just its size, determines whether it’s allowed.
- If you’re mid-flight and a crew member asks you to stop charging it, comply immediately; recharging a power bank in flight is restricted under the current global baseline regardless of which airline you’re on.
- If a power bank is overheating, swelling, or smoking, alert crew immediately and follow their instructions — this is a safety event, not a rules question, and cabin crew are trained to handle a lithium battery incident.
What this is
The 2026 ICAO power bank baseline is a set of restrictions approved by all 36 ICAO Council member states, effective 27 March 2026, governing how many power banks passengers can carry, where, and whether they can be used or charged in flight.
- Examples that count: a 20,000mAh power bank under 100Wh carried in your backpack in the cabin, unused during the flight; a second, smaller power bank kept in a seat pocket as a spare.
- Counter-example — this does NOT include: a power bank packed in checked luggage — that’s now restricted outright under the baseline, because a thermal event in the cargo hold can’t be detected or suppressed by crew the way a cabin event can.
Quick-check table
| Sign | What it usually means |
|---|---|
| Watt-hour rating printed on the unit is under 100Wh | Generally allowed in cabin baggage without special approval |
| Rating is 100–160Wh | Usually needs airline approval in advance — check before departure |
| Rating is over 160Wh | Typically banned from passenger flights outright |
| You’re packing it in checked luggage | Not permitted under the current global baseline — cabin only |
| You want to charge your phone from it mid-flight | The power bank itself generally cannot be recharged in flight; using it to charge another device is a separate question your airline’s policy addresses |
| You’re carrying more than two power banks | Exceeds the ICAO baseline cap — check whether your specific airline enforces this strictly |
| Your airline’s own policy is stricter than this baseline | The airline’s rule wins for that flight — always check before assuming the global minimum applies |
The 2026 baseline vs. checked-bag habits
| Before 27 March 2026 (typical) | From 27 March 2026 (baseline) | |
|---|---|---|
| Number of power banks | Often unrestricted or loosely enforced | Capped at two per passenger |
| Location | Cabin generally recommended | Cabin only, mandatory |
| In-flight charging of the power bank itself | Commonly tolerated | Restricted |
| Storage during flight | Overhead bin often used | Seat pocket, under seat, or on your person — not the overhead bin |
| Watt-hour tiers | Inconsistently enforced | Under 100Wh generally fine; 100–160Wh needs approval; over 160Wh banned |
| Who sets the floor | Individual airlines, inconsistently | ICAO baseline applies globally; airlines can still add stricter rules |
First actions before you fly
- Check the Wh rating on your power bank now, not at the airport — if it’s not printed, check the manufacturer’s spec sheet, since undocumented ratings can lead to confiscation at screening.
- Check your specific airline’s power bank policy before departure — carriers including Emirates, Qatar Airways, Singapore Airlines, Air India, Lufthansa, Cathay Pacific, and British Airways have already aligned with the baseline, and some apply additional restrictions (e.g., lower quantity caps or requiring the power bank to stay visible).
- Pack your power bank in your cabin bag, not checked luggage, and plan to keep it accessible (seat pocket or on your person) rather than in the overhead bin during the flight.
- If you’re carrying a high-capacity power bank (100Wh+), contact your airline in advance for approval rather than discovering the restriction at the gate.
Questions travelers ask
Can I still use my power bank to charge my phone during the flight? The core restriction targets recharging the power bank itself in flight. Using it to charge another device is a related but separate question — check your specific airline’s current policy, since practice varies and some carriers restrict both.
Is this an international law or just some airlines’ policy? It’s a global baseline approved by all 36 ICAO Council member states and intended to apply across all 193 member countries, but ICAO sets minimums — individual airlines can and do layer stricter rules on top.
What happens if my power bank exceeds 160Wh? It’s typically not permitted on passenger flights at all under the current baseline. Very high-capacity banks in that range are effectively excluded from air travel, not just restricted.
Why can’t I pack it in checked luggage anymore, even switched off? A lithium battery thermal event in the cargo hold can’t be detected or actively managed by crew the way a cabin event can be — this is a fire-safety rationale, not a size or convenience rule, and it’s now a hard requirement rather than a recommendation.
Do crew members follow the same rule for their own power banks? Crew are generally permitted to carry and use power banks in line with the aircraft’s operational requirements, which is a distinct allowance from passenger rules.
Will airport security actually check the watt-hour rating? It varies by airport and airline, but with the baseline now in force, expect more consistent questions about rating and quantity than in the recent past — having the rating visible or documented saves time.
