Airplane power outlets, by airline.

Whether your seat has power depends on the airline, the specific aircraft, your cabin class, and sometimes the exact row. ICAO standardized power-bank carrying rules globally on March 27, 2026 (2 banks max, no in-flight recharging), and 10+ major airlines now ban in-flight USE. This is the actual map.

§ 01The 2026 rule change you actually need to knowICAO · Global

The power bank rule everyone is getting wrong this year.

Two facts to land before booking: ICAO standardized the global carry rule on March 27, and a growing list of airlines now ban using the bank in the cabin. Different things.

Rule 01 · Two banks max. Under 100Wh. Carry-on only.

ICAO standardized power-bank carrying rules globally on March 27, 2026. Up to two power banks per passenger, each under 100Wh (about 27,000 mAh at 3.7V — covers every common consumer bank). Carry-on only — checked-baggage power banks have been a worldwide aviation no-go for years. Banks between 100–160Wh require advance airline approval; over 160Wh is banned on commercial aviation.

Rule 02 · In-flight USE is banned on a growing list.

You can carry the bank. You cannot use it. The bank stays in the seat pocket or under the seat — overhead bin not allowed either. American + Delta joined May 1, 2026. Singapore Airlines April 15. Lufthansa Group January 15. Emirates since October 2025. Korean carriers January 26. The full list is in the per-airline matrix below.

Maximum 2 per passenger. Tell the airline at booking. Many low-cost carriers refuse this band entirely.

Banned on commercial aviation

Cabin and hold. No exceptions on passenger flights. Cargo-only with hazmat declaration.

§ 02Insurance · Before the boarding passCover first, fly second

Don't fly uninsured.

Flight cancellation, missed connection, medical at a layover hub — three things the airline isn't buying you back. Single-trip cover is the minimum; annual policies make sense if you fly twice a year or more.

Long haul, covered.

Three thousand miles is plenty of distance for things to get interesting. Heymondo offers single-trip and annual travel insurance. Pick the plan that fits the trip.

§ 04What to pack · Five piecesCarry-on kit

One GaN charger, one bank, three accessories.

The kit works on every airline. Even on carriers that ban in-flight bank USE, you still need the bank for the airport gate and ground transit at destination.

01

65W USB-C GaN charger

1× AC plug · 1× USB-C PD · pocket-sized

Plug into any 110V seat outlet (every AC outlet on a plane is 110V US-spec regardless of airline). USB-C PD gives you 60W to a laptop and 25W to a phone simultaneously. The single most useful piece of kit on a flight.

Our pickAnker 65W GaN charger →
02

10,000 mAh power bank

≈ 37 Wh · USB-C PD · under-100Wh

Carry-on only (never in checked baggage — that's banned worldwide). Under ICAO's 100Wh threshold so 2 are allowed per passenger from March 27, 2026. Charges a phone 2.5 times.

Our pickAnker 10K Power Bank →
03

Short 100W USB-C cable

0.5–1m · 100W rated · braided

Plane seats are tight — a 2m cable lives in your neighbor's lap. A short 0.5m cable from the seat USB or AC outlet to your device is the right length. 100W rating means it doesn't bottleneck the GaN charger.

Our pickAnker 0.9m USB-C cable →
04

USB-only charging cube

1× AC plug · 4 USB ports · CE marked

When you and a seatmate need to charge from one shared AC outlet (British Airways World Traveller, Emirates 777 economy, older Cathay). One AC plug, four USB outputs. Not a power strip — airlines treat outlet-multipliers as fire-risk items.

Our pickUSB-only charging cube →
05

Universal travel adapter

Types A · B · C · F · G · I

For the wall outlet at your destination once you land. Most planes use 110V US-spec at the seat, but the café you charge at in Lisbon or Tokyo doesn't. One universal handles every destination.

Our pickEPICKA Universal Adapter →
The one thing to buy first

A 65W USB-C GaN charger is the single most useful piece of kit on a flight — laptop and phone from one seat outlet. Pack it first.

§ 06FAQ · What people actually askFrom the inbox

Eight questions every traveler emails us.

Q. 01

Can I bring a power bank on a plane in 2026?

Yes, in carry-on only — never in checked baggage, on any airline, worldwide (FAA / IATA / ICAO global rule). Capacity bands: under 100Wh (most consumer banks including 10,000 / 20,000 / 26,800 mAh): allowed, ICAO standardized to a 2-bank-per-passenger maximum from March 27, 2026. 100–160Wh: maximum 2, requires advance airline approval. Over 160Wh: banned on passenger aircraft, full stop.

Q. 02

Can I use my power bank in flight in 2026?

It depends on the airline. As of June 2026, in-flight USE of power banks is banned on: American Airlines (May 1), Delta (May 1), United, Singapore Airlines + Scoot (April 15), Lufthansa Group (Jan 15), Emirates (since Oct 2025), Qatar, EVA Air, China Airlines, JAL, ANA, Korean Air group (Korean / Asiana / Jin Air / Air Busan / Air Seoul / Jeju Air — all from Jan 26), Thai Airways, Air India. Carrying is still allowed; using it in the cabin is not. JetBlue, Southwest, British Airways, Air France/KLM have not announced in-flight use bans as of this writing.

Q. 03

Do all planes have power outlets at every seat?

No. Modern wide-body international aircraft (787, A350, A380, refitted 777, refitted A330) usually have AC + USB at every economy seat. US domestic narrow-body is the weakest category — older 737s and A320s often have nothing in coach, newer retrofits typically add USB-A only, AC is rare in economy. Premium cabins almost always have power. The industry is shifting toward USB-only over AC in economy because USB systems are lighter and cheaper.

Q. 04

What voltage and plug type are airplane AC outlets?

Almost always 110V US-spec, regardless of the airline's nationality. Wattage capped at ~75–100W per outlet. Some longhaul carriers use universal "EmPower"-style outlets that accept US, EU, and UK plugs without an adapter — JetBlue (fleet-wide on A320 / A321), Emirates A380, British Airways longhaul.

Q. 05

Can I charge my laptop on a plane?

Yes, if your seat has an AC outlet and your laptop draws under ~75W. A standard 13–14 inch ultrabook charges fine. A 16-inch gaming laptop with a 200W brick will trip the seat breaker and the outlet shuts off until a crew member resets it. USB-C PD ports on the newest aircraft (Lufthansa Allegris, Delta A220, United new 737 MAX, Qatar QSuite economy) deliver up to 60W, fast enough for most laptops.

Q. 06

USB-A vs USB-C on planes — what's the difference?

USB-A on older aircraft maxes out around 5W (1A at 5V) — slow trickle charging. USB-C with Power Delivery on the newest aircraft hits 15–60W, fast enough to charge a laptop. USB-C is still the exception — present on Lufthansa Allegris (A350-1000), Delta A220 retrofits, the new United 737 MAX cabin, Qatar QSuite economy, and select retrofits. Most planes are USB-A only. The universal fix: bring a small GaN USB-C charger and plug into the AC outlet.

Q. 07

What if my seat doesn't have power and I need it?

Charge fully at the gate before boarding (most major hubs now have outlets at most gates), top up with a power bank in-flight if the airline permits it (check the ban list in this guide). Premium cabins almost always have power if upgrade availability exists. Bring offline maps and downloaded content for the flight regardless — even working outlets can fail.

Q. 08

Can I bring a power strip in my carry-on for flights?

Not recommended. Many airlines now treat outlet-multipliers and power strips as fire-risk items (the same reasoning cruise lines use). The safe alternative is a small AC + USB travel cube — one plug, multiple USB ports. Compact and won't get questioned at security.

Pack the GaN. Charge at the gate. Don't fight the new bank rules.

Thirteen airlines, two ICAO rules, a kit that works on every flight. Whichever airline you board, the seat power picture is in the matrix above — and the bank stays in your seat pocket, not the overhead bin.
