Yes, you can generally take a power bank on a flight, but there are strict rules about where they must be packed and their capacity. Understanding these regulations is key to a stress-free journey.
Planning a trip and wondering if your trusty power bank can accompany you? It’s a question many travelers grapple with, and for good reason. We rely on these portable chargers to keep our phones, tablets, and other essential gadgets alive, especially during long journeys. The thought of being stuck with a dead device at 30,000 feet is enough to cause a bit of anxiety. Thankfully, with a little knowledge, you can ensure your power bank flies with you without a hitch. This guide will break down everything you need to know, from airline regulations to best practices, so you can keep your devices powered up from departure to arrival.
Understanding Airline Regulations for Power Banks
Airlines have specific rules for carrying power banks, primarily for safety reasons. These regulations focus on the lithium-ion batteries inside most power banks, which can pose a fire risk if damaged or misused. Understanding these guidelines is the first step to ensuring a smooth travel experience.
Why the Strict Rules on Power Banks?
The primary concern for airlines is the potential for lithium-ion batteries to overheat and cause a fire. These batteries, while incredibly useful, can be volatile under certain conditions. Airlines err on the side of caution to protect passengers and crew.
Lithium-Ion Batteries: The Core Issue
Lithium-ion batteries are found in most modern electronics, including power banks. They offer high energy density, meaning they can store a lot of power in a small package. However, if punctured, short-circuited, or exposed to extreme heat, they can enter a state called thermal runaway, leading to fire or explosion. This is why regulations focus heavily on how these batteries are transported.
What the FAA (and other Aviation Authorities) Say
In the United States, the Federal Aviation Administration (FAA) has clear guidelines. Power banks are considered “spare batteries” and must be carried in your carry-on baggage. They are strictly prohibited from checked luggage. Similar regulations are enforced by the European Union Aviation Safety Agency (EASA) and other international aviation bodies.
Key Regulations at a Glance
Carry-on Only: Power banks must always be in your carry-on bag.
Capacity Limits: Most airlines restrict power banks to a maximum capacity of 100 watt-hours (Wh). Some may allow up to 160 Wh with special approval.
Protection: Power banks should be protected from short circuits, such as by keeping terminals covered or placing them in a protective pouch.
By adhering to these simple rules, you can avoid any issues at the security checkpoint. It’s always a good idea to check your specific airline’s policy before flying, as minor variations can exist.
Power Bank Capacity Limits: Watt-Hours Explained
The most common restriction you’ll encounter is the watt-hour (Wh) limit for power banks. Understanding this metric is crucial for choosing the right power bank for travel. It’s a simple calculation that ensures your power bank falls within airline safety standards.
Calculating Watt-Hours (Wh)
The watt-hour rating of a power bank is usually printed on the device itself, often on the back or bottom. If it’s not readily visible, you can calculate it using the battery’s voltage (V) and its milliampere-hour (mAh) rating. The formula is:
`Watt-hours (Wh) = (mAh × V) / 1000`
For example, a typical 10,000 mAh power bank with a 3.7V battery would be:
`Wh = (10,000 mAh × 3.7V) / 1000 = 37 Wh`
This falls well within the common 100 Wh limit.
The 100 Wh Sweet Spot
Most airlines allow power banks with a capacity of up to 100 Wh without requiring special permission. This covers the vast majority of portable chargers available on the market, from small pocket-sized units to larger ones capable of charging a laptop. A 100 Wh power bank is generally sufficient for multiple phone charges or a significant boost for other devices.
When You Need Approval: 100 Wh to 160 Wh
If your power bank exceeds 100 Wh but is 160 Wh or less, you will likely need to seek approval from your airline before your flight. This often involves contacting the airline’s customer service or special assistance department in advance. They may ask for the power bank’s specifications and have specific requirements for how it’s packed.
What About Devices Over 160 Wh?
Power banks exceeding 160 Wh are generally not permitted on commercial passenger flights at all. These are very large, high-capacity units designed for more demanding applications, and their battery size poses too significant a risk for air travel.
Packing Your Power Bank: Carry-On vs. Checked Luggage
This is perhaps the most critical rule to remember: power banks and spare lithium-ion batteries must travel in your carry-on baggage. This isn’t a suggestion; it’s a non-negotiable safety regulation.
The “Why” Behind Carry-On Rules
The reasoning is simple: if a power bank were to overheat or catch fire in the cargo hold, it could go undetected for a long time, potentially leading to a catastrophic event. In the cabin, flight attendants are trained to deal with such emergencies, and the fire is more likely to be noticed and extinguished quickly. This is why you’ll see signs at airport security reminding passengers of this rule.
What Happens if You Pack It in Checked Luggage?
If you accidentally pack a power bank in your checked luggage, it will likely be confiscated by security personnel at the gate or baggage check. You’ll be forced to leave it behind. To avoid this, always double-check your bags before heading to the airport.
Protecting Your Power Bank in Your Carry-On
Even within your carry-on, it’s wise to protect your power bank. Ensure its terminals are not exposed to anything metallic that could cause a short circuit. Many power banks come with a protective case or cover. If yours doesn’t, you can use a small plastic bag or a piece of tape over the ports to prevent accidental contact.
Best Practices for Carry-On Storage
Keep your power bank easily accessible in your carry-on bag. This makes it simple for security to inspect if needed and convenient for you to use during your flight. A dedicated tech pouch or a side pocket in your backpack is often ideal.
The 2-Power Bank Rule and Other Restrictions
Beyond capacity, there can be other limitations on how many power banks you can bring and how they are handled. Being aware of these can prevent last-minute confusion.
How Many Power Banks Can You Bring?
While the 100 Wh limit is common, the number of power banks you can carry is also regulated. Generally, passengers are allowed to carry a reasonable number of spare batteries for personal use. This often translates to a limit of two to four power banks, depending on their individual capacity and airline policies. Always verify with your airline if you plan to travel with multiple devices.
Devices in Use During Flight
Once you’re on the plane, the rules for using your power bank can vary. While many airlines permit the use of power banks to charge devices during the flight, some may restrict their use during critical phases like takeoff and landing. Always follow the instructions of the flight crew.
What About Built-in Batteries?
Devices with batteries installed (like laptops or phones) are treated differently than spare batteries or power banks. These installed batteries generally have higher capacity limits allowed within the device itself, and the devices themselves can often be in checked baggage, provided they are turned off and protected from accidental activation. However, for spare batteries and power banks, the carry-on rule is paramount.
Choosing the Right Power Bank for Air Travel
Selecting a power bank that meets airline regulations and your travel needs is key. Consider both capacity and physical size to ensure compliance and convenience.
Factors to Consider When Buying a Travel Power Bank
Capacity (Wh): Aim for power banks under 100 Wh to avoid hassle. A 10,000 mAh to 20,000 mAh unit is usually sufficient for most travelers.
Size and Weight: Lighter and more compact power banks are easier to carry in your hand luggage.
Ports: Consider how many devices you need to charge and what types of ports (USB-A, USB-C, PD) you require.
Durability: A sturdy build can withstand the rigors of travel.

Popular Travel-Friendly Power Bank Capacities
5,000-10,000 mAh: These are typically the smallest and lightest, often under 37 Wh. Ideal for a single phone charge or two.
10,000-20,000 mAh: These offer a good balance of capacity and portability, usually falling between 37 Wh and 74 Wh. They can charge a smartphone multiple times or provide a significant boost to a tablet.
20,000-27,000 mAh: While still often under the 100 Wh limit (e.g., 27,000 mAh at 3.7V is ~100 Wh), these are larger and heavier. They can charge laptops and multiple devices.
Example: Power Bank Capacity Comparison
| Capacity (mAh) | Voltage (V) | Calculated Watt-hours (Wh) | Airline Compliance (under 100 Wh) |
| :————- | :———- | :————————- | :——————————– |
| 5,000 | 3.7 | 18.5 | Yes |
| 10,000 | 3.7 | 37 | Yes |
| 20,000 | 3.7 | 74 | Yes |
| 26,800 | 3.7 | 99.16 | Yes |
| 30,000 | 3.7 | 111 | Requires Airline Approval |
Note: Voltage can vary slightly, but 3.7V is a common standard for power bank internal batteries.*
Brands to Consider
Reputable brands like Anker, RAVPower, Aukey, and Belkin often produce power banks that clearly state their Wh capacity, making them a safe bet for air travel. Always check product descriptions for Wh ratings.
What If My Power Bank Exceeds the Limit?
If you discover your power bank is over the 100 Wh limit (but under 160 Wh), don’t panic. There are still options, but they require proactive steps.
Contacting Your Airline in Advance
The most crucial step is to contact your airline well before your travel date. Explain the specifications of your power bank and inquire about their policy for carrying batteries between 100 Wh and 160 Wh. Airlines typically have a process for approving these items.
Preparing Documentation
Have the power bank’s specifications readily available. This includes the mAh capacity, voltage, and calculated Wh rating. You might need to show this documentation to the airline when booking or at the airport.
Alternatives if Approval Isn’t Possible
If your airline does not permit your power bank, or if it exceeds the 160 Wh limit, you will have to make alternative arrangements. This might mean purchasing a new, compliant power bank at your destination or leaving the high-capacity one at home. It’s far better to know this beforehand than to have it confiscated at security.
Power Banks on International Flights
Regulations can vary slightly between countries and airlines, especially for international travel. It’s always wise to be extra diligent.
Checking International Aviation Standards
While the core principles are similar, always check the specific regulations of the countries you are flying to and from, as well as the airline’s policies. Bodies like the International Civil Aviation Organization (ICAO) provide guidelines, but individual countries and airlines implement them.
Common International Carrier Policies
Major international carriers generally follow the FAA/EASA guidelines. They typically allow power banks up to 100 Wh in carry-on baggage and may allow larger ones (up to 160 Wh) with prior approval. However, rules can differ, so verification is key. For instance, some countries might have stricter limits on the number of spare batteries allowed per passenger.
Navigating Customs and Security
Be prepared for security checks. Having your power bank readily accessible and clearly marked with its capacity will expedite the process. If you have received airline approval for a larger power bank, keep that documentation handy.
Can You Use a Power Bank During the Flight?
Once you’ve successfully navigated security, you’ll likely want to use your power bank to keep your devices charged during the flight. Here’s what you need to know.
In-Flight Usage Policies
Most airlines permit the use of power banks to charge personal electronic devices during the flight. This is a common practice, and you’ll often see passengers topping up their phones or tablets. However, always pay attention to the flight crew’s announcements.
Restrictions During Critical Phases
Some airlines or specific flight conditions might restrict the use of any electronic devices, including charging them with power banks, during takeoff and landing. These are considered critical phases of flight for safety reasons. Always comply with crew instructions.
Keeping Devices Charged
Having a charged device can make a long flight much more enjoyable, whether it’s for entertainment, work, or staying connected. Ensure your power bank is fully charged before you leave home, as in-flight charging ports are not always available or reliable.
Power Banks vs. Other Battery-Powered Devices
It’s helpful to understand how power banks fit into the broader category of devices with lithium-ion batteries.
Other Allowed Devices
Laptops, smartphones, tablets, cameras, and e-readers with their installed batteries are generally allowed in both carry-on and checked baggage (with specific conditions, like being turned off in checked bags). However, spare batteries and power banks for these devices are strictly carry-on only.
What About E-Cigarettes and Vapes?
Many airlines also prohibit e-cigarettes and vaping devices in checked luggage. They must be carried in your carry-on bag, and their use is typically forbidden on the aircraft. This is due to the lithium-ion battery and the potential for malfunction.
Battery Safety in General
The overarching principle is that devices with lithium-ion batteries that are not installed in equipment must be in carry-on baggage and protected from damage or short circuits. This applies to power banks, spare camera batteries, and other similar portable power sources.
