Do Korean Air planes have power outlets?
Yes — on every Korean Air jet except the 737-900. Korean Air says it fits its own power socket at every First and Prestige seat, and one shared socket for each group of seats in economy: 110V, rated 75 to 150 W depending on the aircraft. The USB port at the seat is USB-A on most of the fleet; USB-C comes only on the 787-10, the A321neo and the 777-300ERs refitted with the new Premium Class. The 737-900, flown mostly on domestic routes, has no seat power at all. Power banks: since 26 January 2026 you can't use or charge one on board. You may carry two, in the cabin, terminals taped or each in its own plastic bag, and never in the overhead bin.

Does Korean Air have outlets? Yes — at nearly every seat, but economy shares.
First and Prestige: your own socket. Korean Air's fleet page says in-seat power is 'installed at every seat in First Class and Prestige Class'. The retrofitted 777-300ER's Premium Class has power too.
Economy: 'a power supply is shared for each seat group'. On a 737-900ER in March 2026 a reviewer counted two sockets for every three seats. Most types add a USB-A port at each seat; on the 787-10 and refitted 777, Korean Air lists USB-C, two ports for every three seats.
USB-C: only the 787-10, the A321neo and the refitted 777-300ER (the one with Premium Class). Prestige on the 787-10 has two USB-C ports, 60W and 45W, and no USB-A. Almost everywhere else Korean Air lists USB-A, First Class included.
No power at all on the 737-900, a mostly domestic type with nine left in December 2025. Korean Air says so, and a December 2025 economy flight found no outlets or USB ports.
Power banks: two per person, cabin bag only, never used or charged in flight since 26 January 2026. Up to 100 Wh needs no approval, 100–160 Wh needs Korean Air's, over 160 Wh can't fly.
§ 02The cabin kit · Before the boarding passBanks · short cables · adapters
Board it charged.
On Korean Air the table below is the in-flight plan, because the bank in your bag has to stay off until you land. Most seats have a socket; the domestic 737-900 has none. Fill the phone and the bank before boarding, and let the seat do the rest.
§ 03Power by aircraftAC · USB-A · USB-C, per cabin
Every Korean Air aircraft, cabin by cabin.
Find your aircraft on the booking or seat map first — the same flight number can be a different jet day to day. Where a cell reads Not listed, no source we can stand behind says that outlet is there or isn't; we'd rather tell you that than guess. Carry a bank for the gate and arrival regardless.

Korean Air's newest widebody and its best-equipped. Prestige Suites 2.0 has a wireless charging pad, two USB-C ports rated 60W and 45W, and a universal 110V socket low by the seat. There's no USB-A: a reviewer in January 2026 wished Korean Air had kept one. In economy Korean Air lists a shared socket and 'USB-C ports (2 for every 3 seats)', so bring a USB-C cable.

The 777-300ERs that still carry First Class (Kosmo Suites) come in two layouts, and Korean Air lists a power socket and a USB-A port in every cabin of both. A reviewer in economy from London in September 2026 found 'a USB-A port was in the seatback, and AC power was below and between the seats'. No USB-C is listed for these cabins.

The superjumbo, still flying after its planned retirement was postponed. First has two USB-A ports in the centre storage unit and an AC socket on the side of the seat. Economy has a universal socket under the seats and a USB-A port in the seatback; a reviewer writing in December 2025, after more than 15 hours in economy, called it 'the elderly USB-A port', and it got there. Korean Air lists no USB-C on it.

In First, a 2025 reviewer found the USB-A port in a container with the remote and the universal socket by the footwell, where you have to reach for it. No USB-C is listed.

The 737 MAX. Korean Air lists a socket and a USB port in both cabins but says the port 'type (Type A/Type C) may differ depending on the aircraft type'. Economy reviewers in 2024 and 2025 found USB-A, with two universal sockets for every three seats. Check the port before you pack only one cable.

Not to be confused with the plain 737-900. The ER has power: a reviewer from Hong Kong in March 2026 found universal sockets 'two for each set of 3' and 'a USB-A port by the seat in front, though understandably no USB-C charging'. One of his three sockets didn't work, so if you need one, plug in early.

The exception. Korean Air's fleet page says seat power is 'Not available on Boeing 737-900 aircraft', and a December 2025 economy flight found no power outlets, no USB ports, no seatback screens and no Wi-Fi. It flies mostly domestic routes, and nine were left at the end of 2025. Board charged: the bank can't be used either.
§ 04The power-bank ruleEffective 26 January 2026
Carry it. But you can't use it in the air.
Applies on every flight operated by Korean Air and four other Hanjin Group airlines: Asiana, Jin Air, Air Busan and Air Seoul, all from 26 January 2026. Jeju Air, which belongs to a different group, brought in its own ban four days earlier. The carriage limits below are from Korean Air's restricted-items page, which prints no start date; the date and the seat-pocket rule come from the group's announcement as reported in January 2026.
01No use, no charging: "The use and charging of power banks on board are strictly prohibited." Board with the bank full and the phone full.
02Two power banks per person. Up to 100 Wh (about 27,000 mAh) needs no approval; 100–160 Wh needs Korean Air's approval, and still counts toward the two; over 160 Wh is "Carriage not permitted".
03Cabin baggage only. Power banks are prohibited in checked bags.
04Protect the terminals: each bank "placed individually in transparent plastic bags or with terminals wrapped with electrical tape".
05Never in the overhead bin. Korean Air's page says storing them there "is strictly prohibited"; the January announcement says to keep them in the seatback pocket or under the seat in front.
§ 05Quirks you won't read elsewhereKorean Air specifics
◆ Quirk 01
The 737-900 has no seat power at all
Every other Korean Air jet has power in every cabin. The 737-900 has none: Korean Air's fleet page says so, and a December 2025 economy flight found no outlets, no USB ports, no screens and no Wi-Fi. It's not the 737-900ER, which has sockets and USB-A. Nine were left at the end of 2025, mostly on domestic routes. Check the aircraft type on your booking; with the bank banned on board, board fully charged.
◆ Quirk 02
On the 777-300ER, Premium Class is the tell
Korean Air flies three 777-300ER layouts. The refitted one, introduced from mid-September 2025, has the new Premium Class, and Korean Air lists USB-C in every cabin. The two older ones still have First Class and USB-A. If your booking or seat map shows Premium Class, you're on the refit; if it shows First, bring a USB-A cable.
◆ Quirk 03
USB-C is on three types; the rest is USB-A, First included
Korean Air lists USB-C only on the 787-10, the A321neo and the refitted 777-300ER. Every other cabin page we read lists USB-A, apart from the 737-8, where Korean Air says the type may differ. That includes the Kosmo Suites in First on the A380, 747-8I and older 777-300ER. On the 787-10 the Prestige suite has no USB-A at all, the reverse problem. Pack a USB-A-to-C cable and a USB-C one.
◆ Quirk 04
Economy shares its sockets
Korean Air's own wording: in economy, 'a power supply is shared for each seat group'. Reviewers on the A321neo, 737-8 and 737-900ER counted two sockets for every three seats, below and between the seats. A small USB charger with two ports lets you share yours with the person who didn't get there first.
◆ Quirk 05
110V and a wattage ceiling
Korean Air rates its seat sockets at 110V/60Hz, with 'the maximum power available from each outlet' between 75 and 150 W 'depending on the aircraft type'. That covers a phone, a tablet or a 65W laptop charger on every type. Most plugs go straight in, but Korean Air says 'a separate adapter may be required for special plug types used in some countries'.
◆ Quirk 06
Asiana joins Korean Air on 17 December 2026
Asiana still flies as a separate airline until 17 December 2026, when Korean Air absorbs it. Its cabins aren't covered here, though the power-bank ban already applies on Asiana flights. Korean Air's fleet pages also list layouts that aren't in its own fleet count, such as a 495-seat A380 and 777-200ERs; those aren't in the table either. On an Asiana-operated codeshare, the seat power is Asiana's.
§ 06The Korean Air flight packPower bank first
One bank first, then three backups.
Korean Air bans using a power bank on board, but nearly every seat has power: a socket in First, Prestige and Premium, a shared one in each economy seat group. The ports are mostly USB-A; USB-C only on the 787-10, the A321neo and the refitted 777-300ER. The 737-900 has nothing. So the bank is for Incheon and arrival, the GaN charger is for the socket, and a USB-A lead covers the older jets.
A 20,000 mAh USB-C bank under 100 Wh is the most useful thing to pack for a Korean Air trip. You can carry two but not use them in the air, so it earns its place on the ground: Incheon, the gate and arrival.

§ 07Questions about Korean Air powerReal answers
Does Korean Air have power outlets?
Yes, on every aircraft except the 737-900. Korean Air fits a power socket at every First and Prestige seat and shares one per seat group in economy, at 110V. The 737-900, used mostly on domestic routes, has no seat power, no USB and no screens.
Does Korean Air economy have power outlets?
Yes, shared. Korean Air says 'a power supply is shared for each seat group' in economy; reviewers have counted two sockets for every three seats. Most types also have a USB-A port at each economy seat. On the 787-10 and the refitted 777-300ER Korean Air lists USB-C instead, two ports for every three seats. The 737-900 has neither.
Does Korean Air have USB-C ports?
On three types: the 787-10, the A321neo and the 777-300ERs refitted with Premium Class. Prestige on the 787-10 and the refitted 777 gets 60W USB-C, and so does the refitted 777's Premium Class. Almost every other Korean Air cabin page, First Class included, lists USB-A. Bring both cable types if you don't know your aircraft.
Can I use a power bank on a Korean Air flight?
No. Since 26 January 2026 Korean Air says 'the use and charging of power banks on board are strictly prohibited'. You can still carry them in your cabin bag; use them at the gate and after you land. The same rule applies on Asiana, Jin Air, Air Busan and Air Seoul.
What are Korean Air's power bank rules?
Two power banks per person, cabin baggage only, never checked. Up to 100 Wh needs no approval; 100–160 Wh needs Korean Air's approval and counts toward the two; over 160 Wh is not allowed. Each bank goes in its own plastic bag or with its terminals taped, and never in the overhead bin.
Does the Korean Air 777-300ER have outlets and USB-C?
Outlets, yes, in every cabin. USB-C depends on which 777-300ER: the refitted ones with Premium Class, introduced from September 2025, are listed with USB-C in every cabin: 60W in Prestige and Premium, two ports for every three seats in economy. The ones that still have First Class list USB-A only.
Does the Korean Air A380 have power outlets?
Yes. Korean Air lists a power socket and a USB-A port in First, Prestige and economy on its 407-seat A380. First has two USB-A ports and an AC socket at the side of the seat. There's no USB-C.
What voltage are Korean Air's seat sockets?
110V/60Hz, with 75 to 150 W available per outlet depending on the aircraft. Most plugs fit directly, though Korean Air says some countries' plug types need an adapter. A 65W laptop charger is within the limit on every type.
