Is a Portable Charger Banned From Suitcase? Know the Rules in 2026

You have packed your clothes, passport and travel essentials, but then comes one small question: is a portable charger banned from suitcase? For first-time flyers especially, battery rules can be easy to overlook, and what seems like a simple item may be treated differently at the airport.

Knowing the rules before you pack can help you avoid last-minute confusion at check-in or security. This guide explains what you need to know about travelling with a portable charger, from airline requirements to packing and battery limits.

Quick Answer

• You can take a portable charger on a plane, but it must be carried in your hand luggage rather than packed in a checked suitcase.
• A power bank must have a battery capacity of 100Wh or less to be carried by passengers under the latest 2026 IATA rules.
• Power banks over 100Wh are not permitted, even though some other lithium batteries between 100Wh and 160Wh may be allowed with airline approval.
• Passengers may carry a maximum of two power banks, and each one should be protected against accidental activation or short circuits.
• Always check your airline’s own requirements before flying, as carriers may apply additional restrictions.

Can You Take a Portable Charger in a Suitcase on a Plane?

Can you take a battery pack on a plane? Yes, but where you pack it matters. A portable charger can travel with you in a cabin suitcase, backpack or other hand luggage, but it should not be left inside checked baggage. The key difference is whether the suitcase stays with you in the cabin or is placed in the aircraft hold. Portable chargers contain lithium-ion batteries, so aviation rules treat them differently from many ordinary travel accessories. If your cabin bag needs to be checked at the gate for any reason, remove the portable charger before handing over your luggage.

Why Are Portable Chargers Not Allowed in Checked Luggage?

Portable chargers are not allowed in checked luggage because they contain lithium-ion batteries, which can overheat, short-circuit or catch fire if they are damaged or packed incorrectly.

The main concern is a thermal event, where a battery becomes dangerously hot and may ignite. According to the UK Civil Aviation Authority, power banks should remain in the cabin rather than the aircraft hold because lithium batteries can overheat and cause a fire.

Keeping a portable charger in hand luggage also means that any signs of overheating, smoke or damage can be noticed more quickly during the flight. This is why checked baggage rules for power banks are stricter than for many ordinary travel accessories.

What Are the Power Bank Flight Restrictions in the UK?

Current UK power bank flight restrictions cover where power banks can be packed, how many you can carry, their battery capacity and how they may be used onboard. The rules became stricter in 2026 following updated international aviation safety requirements.

• Carry power banks in hand luggage: Power banks must stay in carry-on baggage and must not be packed in checked luggage.
• Carry no more than two: Under the updated 2026 rules, passengers may carry a maximum of two power banks per person.
• Check the battery capacity: IATA’s 2026 passenger guidance advises passengers to carry lithium-ion power banks rated at 100Wh or less. If you have a higher-capacity model, check with your airline before travelling, as additional approval or restrictions may apply.
• Do not recharge a power bank onboard:ICAO’s updated international specifications, effective from 27 March 2026, prohibit recharging power banks from an in-aircraft power supply.
• Keep the power bank accessible:IATA’s 2026 passenger guidance advises passengers not to store power banks in overhead lockers and not to use them to power other devices during taxi, take-off or landing.

Airlines can apply stricter conditions than the general guidance, so check your carrier’s latest policy before departure.

How Should You Pack a Portable Charger for a Flight?

Packing a portable charger correctly can help prevent delays at airport security and reduce the risk of accidental damage or short circuits during travel.

• Keep it in your hand luggage: Place your power bank in a cabin bag, backpack or personal item rather than checked baggage.
• Protect it from short circuits: Keep the power bank in a protective pouch or its original packaging, and prevent exposed terminals from coming into contact with coins, keys or other metal objects.
• Check its condition before travelling: Do not take a power bank that is swollen, cracked, leaking, unusually hot or otherwise damaged.
• Keep the battery information visible: Make sure the capacity or Wh rating printed on the power bank can still be read, as airline or security staff may need to check it.
• Remove it if your cabin bag is checked: If your hand luggage needs to be placed in the aircraft hold, take the portable charger out before handing over the bag.
• Keep it accessible during the journey: Avoid burying the power bank deep inside your luggage so it can be reached easily if airline staff need to inspect it.

UK government guidance also makes clear that airlines and airports may apply their own restrictions, so always check the operating carrier’s latest dangerous-goods or restricted-items page before departure.

Portable Charger vs Regular Charger: Are the Flight Rules the Same?

No. A portable charger or power bank contains a rechargeable lithium battery, so it is subject to specific aviation restrictions. A standard plug-in charger, by contrast, does not store electrical energy in the same way and is generally treated differently when you travel.

• Portable chargers and power banks: These must follow airline battery rules, including limits on where they can be packed, how many you can carry, and how they may be used during the flight.
• Wall chargers and USB adapters: Standard chargers can generally be packed in either hand luggage or checked baggage because they do not contain a standalone lithium battery.
• Charging cables: USB-C, Lightning and other charging cables can usually be packed in either type of baggage and are not subject to the same lithium-battery restrictions as power banks.

If you are travelling with a laptop or several devices, a plug-in charger can be useful alongside a compliant power bank. The Anker Laptop Charger (140W, 4-Port, PD 3.1) with USB-C Cable is designed to charge multiple devices from a mains power source, so it should not be confused with a portable battery pack.

How to Choose a Portable Charger for Air Travel?

The right portable charger depends mainly on how many devices you carry, how often you expect to recharge them, and whether you need to power a phone or a laptop. For air travel, capacity and output are the two most useful specifications to compare.

• Choose the right capacity for your trip: A 5,000mAh power bank is best for emergency top-ups, while 10,000mAh is a practical choice for most travellers who mainly charge a phone. For longer trips or several devices, 20,000mAh offers more reserve power without approaching the 100Wh limit. At a nominal 3.7V, 20,000mAh is about 74Wh, while 27,000mAh is approximately 99.9Wh.
• Match the output to your devices: Around 20–30W is usually enough for fast-charging smartphones. Tablets and lighter laptops may benefit from 45–65W USB-C PD, while more demanding laptops can require 100W or more for faster charging.
• Consider how many devices you charge at once: If you carry a phone, tablet, earbuds and laptop, choose a model with multiple ports and check its total output, not just the maximum rating of one port. Charging several devices simultaneously can reduce the power available to each one.
• Balance capacity with weight: Higher-capacity models provide more charging time but are also heavier. A 10,000mAh model is often easier to carry for day trips or short breaks, while 20,000–27,000mAh models are better suited to long journeys, laptop users or travellers who may spend extended periods away from a wall socket.

For most travellers, 10,000mAh offers the best balance between portability and backup power. If you regularly travel with several devices or a laptop, 20,000mAh or more may be more practical, provided the power bank remains within the applicable airline limit.

The Best Power Banks for Travel in 2026

Anker offers several travel-friendly power banks for different charging needs, from compact phone top-ups to high-output laptop charging.

Conclusion

A portable charger is banned from a checked suitcase, but it can still be taken on a plane when packed correctly. Under the 2026 guidance, power banks should stay in hand luggage, passengers are limited to two, and each one should be rated at 100Wh or less. They should not be recharged from an in-aircraft power supply and should remain accessible during the flight rather than being stored in an overhead locker.

Before travelling, check your airline’s latest policy as carriers may apply stricter requirements. Choosing a clearly labelled, compliant power bank and packing it correctly can help you pass through the airport with fewer surprises.
