Can You Bring a Portable Charger on a Plane? Know the Rules

Can you bring a portable charger on a plane? It’s a common question for travellers who rely on their phones, tablets, and laptops while flying. Portable chargers, also known as power banks, contain lithium-ion batteries, which means they’re subject to specific airline and airport security rules.

In this guide, we explain exactly when you can bring a portable charger on a plane, the key power bank rules to follow before flying, and how to pack and choose a charger that’s safe for air travel—so you can pass security with confidence and avoid unnecessary delays.

Can You Bring a Portable Charger on a Plane?

Yes, you can bring a portable charger on a plane, but it must be carried in your hand luggage, not checked baggage. Airlines allow most power banks for personal use, but there are rules based on battery capacity:

• Up to 100 Wh (about 27,000 mAh):Allowed in carry-on with no approval needed. Most phone or tablet chargers fall into this category.
• 101–160 Wh: Allowed only with airline approval. You’re usually limited to two of these per passenger.
• Over 160 Wh: Not permitted on passenger flights. These are considered high-risk and are generally used for professional or industrial equipment.

Power Bank Rules You Must Follow Before Flying

When flying with a portable charger, following airline rules is essential for safety and to avoid delays at security. Here are the key power bank rules you must follow before flying:

1. Carry in hand luggage only

Power banks must never go in checked baggage. Lithium-ion batteries can overheat or catch fire, and keeping them in the cabin ensures any issues can be handled immediately.

2. Check the capacity (Wh) of your power bank

• Up to 100 Wh– Allowed in carry-on without airline approval.
• 101–160 Wh– Allowed only with airline approval. Usually, a maximum of two per passenger is permitted.
• Over 160 Wh– Not allowed on passenger flights.

To calculate watt-hours if only mAh is listed: Wh = mAh / 1000 × Voltage (V)

Most lithium-ion power banks use a 3.6–3.7V nominal voltage.

3. Protect the terminals

Cover exposed battery contacts with tape, place the power bank in a protective pouch, or keep it in its original packaging to prevent short circuits.

4. Avoid damaged or swollen batteries

Never bring a power bank that shows signs of swelling, cracking, or leakage. These can pose serious safety risks.

5. Limit the number of power banks

Airlines generally allow more than one, but keep it reasonable—two to three per passenger is standard. All must comply with the capacity rules above.

6. Follow airline-specific instructions

Some airlines have stricter rules about in-flight usage or charging. Always check with your carrier before flying.

Airline-Specific Rules in the UK & Europe

Different airlines may add their own rules on top of general regulations, so it’s important to check before you fly. Here’s a breakdown of UK and European airline policies for portable chargers:

British Airways

• Under 100 Wh:Allowed in carry-on without approval.
• 101–160 Wh: Allowed with prior airline approval.
• Over 160 Wh: Not permitted.
• Maximum of four spare batteries under 100 Wh per passenger.

easyJet

• Under 100 Wh:Permitted in hand luggage.
• 101–160 Wh:Must contact the airline before flying.
• Over 160 Wh:Not allowed.

Ryanair

• Power banks only in carry-on luggage.
• Up to 100 Wh: Allowed freely.
• Over 100 Wh:Airline approval required.
• Terminals must be protected to avoid short circuits.

European Union Airlines (EASA Countries)

• Most follow 100 Wh / 160 Wh limits in line with IATA guidelines.
• Recent guidance encourages stricter enforcement due to lithium battery incidents.
• Some carriers may limit quantity or restrict in-flight usage.

Tip: Even if your power bank is allowed under general rules, individual airlines may have stricter policies, especially for high-capacity chargers or multiple units. Always check the airline’s official website before packing.

How to Choose a Plane-Safe Portable Charger

When choosing a plane-safe portable charger, first make sure its capacity complies with airline regulations. Beyond that, several other factors determine how well it fits your devices and lifestyle.

1. Choose the right capacity (under 100Wh)

To stay hassle-free, aim for a charger under 100Wh, which is allowed in carry-on luggage without airline approval on most airlines.

Power Bank Capacity	Voltage (V)	Estimated Watt-Hours (Wh)	Best for
5,000 mAh	3.7 V	18.5 Wh	Emergency phone top-ups, short day trips
10,000 mAh	3.7 V	37 Wh	Daily travel, 1–2 phone charges
20,000 mAh	3.7 V	74 Wh	Long flights, phones + tablets
26,800 mAh	3.7 V	99 Wh	Power users, multiple devices, extended travel

26,800 mAh is often the maximum capacity that typically stays under the 100Wh airline limit, ideal if you want the most power without extra approvals.

2. Match output power to your devices

• Phones:20–30W USB-C PD
• Tablets: 30W+
• Laptops:45–65W or higher

Ensures fast, safe charging without overheating.

3. Portability and size

Compact, lightweight chargers are easier to carry and fit in hand luggage. Look for slim designs with multiple ports for convenience.

4. Safety certifications

Choose chargers with CE, FCC, or other recognized approvals. Avoid unbranded or cheap models that may fail security checks.

5. Multiple device support

If you travel with several devices, pick a charger with multiple output ports and sufficient total wattage.

How to Pack Portable Chargers for Airport Security

Packing your portable chargers correctly is essential to avoid delays or confiscation at airport security. Follow these tips to make your travel smooth and stress-free:

1. Keep them in your carry-on

All power banks must go in hand luggage, never in checked baggage, due to fire risks with lithium-ion batteries. Place them in an easily accessible pocket or compartment for quick removal during security screening.

2. Protect the terminals

Cover exposed metal contacts with tape or store chargers in a pouch or case. This prevents short circuits and meets airline safety requirements.

3. Separate multiple chargers

Avoid stacking chargers together; leave a small space or use pouches to prevent heat buildup. If carrying more than one device, make sure each is individually protected.

4. Label your charger

Clearly display the capacity (Wh or mAh) and voltage if it’s not printed. This helps security officers verify that your power bank complies with regulations.

Pro Tip: Place your power bank under the seat in front of you during the flight. It’s safer and easier to access if needed, compared to the overhead bin.

Conclusion

FAQs

Can you bring a portable charger on carry-on?

Yes, all portable chargers or power banks must be carried in your hand luggage. Airlines prohibit them in checked baggage due to lithium-ion battery risks. Keep them protected, with terminals covered or in a pouch, and place them in an easily accessible compartment for security checks. Chargers under 100 Wh usually require no approval, while larger ones (101–160 Wh) may need prior airline authorization. Following these rules ensures smooth passage through airport security and safe travel with your devices.

Can I bring a 20000mAh power bank on a plane?

Yes, a 20,000mAh power bank is typically under 100 Wh, which means it can be carried in your hand luggage without airline approval. It’s perfect for long flights or travel days, capable of charging phones multiple times. Ensure it’s in good condition, with no swelling or damage, and keep terminals protected. Avoid placing it in checked luggage, and check airline-specific rules for high-capacity or multiple chargers to prevent delays at security.

Where do you put a portable charger when flying?

Portable chargers should always be stored in carry-on bags. During security, place them in an accessible pocket or separate tray, similar to laptops or tablets. On the plane, the safest place is under the seat in front of you, rather than the overhead bin. This ensures it’s within reach if needed and reduces risk in case of a battery issue. Avoid stacking chargers or exposing terminals to metal objects, and follow airline rules regarding in-flight charging.

Can I take more than one portable charger onboard?

Yes, most airlines allow passengers to carry two to three power banks, as long as each meets the approved capacity limits. Chargers under 100 Wh are usually unrestricted, while 101–160 Wh units require airline approval. Keep each charger protected and separated to prevent short circuits. Always check your airline’s rules, as policies may vary, and never pack them in checked baggage. Following these guidelines ensures compliance, safety, and convenience during your flight.
