Can you bring a power bank on a plane in 2026? The short answer is yes—but only if it is in your carry-on bag and rated under 100Wh (approximately 27,000mAh).
While a standard 5,000mAh to 10,000mAh charger is usually a safe bet, the rules get tricky if you have a larger device or a faded label. Read on to discover how to calculate your device's rating, which airlines enforce stricter limits, and the essential safety steps to prevent your charger from being confiscated at the gate.
Can You Bring a Power Bank on a Plane?
The answer is yes, you can bring a power bank on a plane, but you must pack power banks in your carry-on baggage or keep them on your person. You are strictly prohibited from packing portable chargers or loose lithium batteries in checked luggage.
This regulation exists because lithium-ion batteries present a fire risk. If a battery malfunctions and ignites inside the cargo hold, the automatic fire suppression systems may not be able to contain a lithium fire effectively. When the device is in the cabin, the flight crew is trained to handle such incidents immediately, ensuring the safety of all passengers. To further minimize risks, it is recommended to choose a high-quality portable charger with a capacity between 5,000mAh and 10,000mAh.
Understanding Watt-hours (Wh) and Milliampere-hours (mAh)
A major source of confusion for travellers is that airline safety rules are written in Watt-hours (Wh), but power banks are sold and marketed in milliampere-hours (mAh). To determine if your charger is compliant, you need to understand the relationship between these two units.
How to Calculate Watt-hours
Watt-hours (Wh) = Capacity (mAh) * Voltage (V)/1000
The standard voltage for most lithium-ion power banks is 3.7V.
Common Capacity Conversions
-
10,000 mAh: （10,000 * 3.7） / 1000 =37 Wh. This is well below the limit and is safe to fly.
-
20,000 mAh: (20,000 * 3.7) / 1000 = 74 Wh. This is also safe and requires no special approval.
-
26,800 mAh: (26,800 * 3.7) / 1000 = 99 Wh. This is effectively the maximum capacity you can bring without airline approval.
-
30,000 mAh: (30,000 * 3.7) / 1000 = 111 Wh. This exceeds the standard 100Wh limit and requires airline approval.
What Capacity Power Bank Can I Bring?
Airlines categorise power banks into three distinct tiers based on their energy capacity. These limits are standardised globally by the IATA.
1. Under 100Wh (Standard Approval)
For the vast majority of travellers, this is the only category that matters. Power banks rated under 100 Watt-hours (Wh) are allowed in carry-on bags without requiring any special permission from the airline. Travelers using compliant devices, such as the RORRY portable charger which clearly displays the Wh rating on the casing, can pass through security checks quickly without needing to calculate conversions manually.
2. 100Wh to 160Wh (Conditional Approval)
Power banks with a capacity between 100Wh and 160Wh fall into a restricted category. These are typically larger, high-capacity chargers designed for laptops or professional camera equipment.
To fly with a power bank in this range, you must receive airline approval. This usually involves notifying the airline staff at the check-in counter or the gate.
3. Over 160Wh (Prohibited)
Any power bank with a rating exceeding 160Wh is strictly forbidden on passenger aircraft. These devices are considered hazardous materials and cannot be carried in either hand luggage or checked bags.
How Many Power Banks Can I Bring?
In addition to capacity limits, there are restrictions on the number of spare batteries you can carry.
For Power Banks Under 100Wh
Most airlines allow a "reasonable number" of spare batteries for personal use. While this is often undefined, the general consensus and TSA guidelines typically suggest a limit of roughly 20 spare batteries per passenger. However, carrying this many may trigger a secondary security screening. For practical purposes, carrying 2 to 3 power banks for personal electronics is never an issue.
For Power Banks Between 100Wh and 160Wh
The rules are much stricter here. You are generally limited to a maximum of two power banks falling within this specific capacity range. Remember, you still need airline approval to bring these on board.

Preparation and Safety Precautions for Travel
Bringing the correct capacity is only the first step. You must also ensure that the device is packed correctly and that the capacity is verifiable by airport security agents.
Verify the Label is Legible
Airport security agents must be able to verify the capacity of your battery. The power bank must have its specifications (capacity in Wh or mAh and Voltage) clearly printed on the casing. If the label on your power bank has faded, been scratched off, or is otherwise illegible, security personnel have the authority to confiscate the device because they cannot verify safety compliance.
Prevent Short Circuits
While in your carry-on bag, the power bank must be protected from metal objects like keys or coins that could bridge the terminals and cause a fire. To prevent this, you should keep the power bank in its original retail packaging or a dedicated pouch. Choosing a charger with built-in cables like those from RORRY is also a great safety measure, as it eliminates the need to carry loose wires that could accidentally tangle or cause short circuits in your bag.
Inspect for Damage
Do not attempt to fly with a damaged battery. If your power bank is swollen, punctured, or producing excessive heat, it is a safety hazard. Security officers are trained to look for damaged batteries and will not allow them on the aircraft.
Turn the Device Off
If your power bank has a physical on/off switch, ensure it is in the "Off" position. This prevents the device from accidentally activating and generating heat while inside the overhead bin.
Manage Your Charge Levels
It is best to board the plane with your power bank charged to around 80% rather than 100%, as this reduces internal pressure and improves safety during flight. Therefore, knowing exactly how long it takes to charge a power bank is crucial—it ensures you can time your charging session perfectly before heading to the airport.
Conclusion
To sum up, flying with a power bank in 2026 is simple: always pack it in your carry-on and ensure it is rated under 100Wh (approx. 27,000mAh). Whether you are using a standard charger or a travel-ready option like RORRY, double-check that the label is legible to avoid confiscation. By following these rules and basic safety tips, you can pass through security smoothly and stay powered up for your trip.
FAQs
Can you fly with a 30000mAh power bank on a plane?
It depends on the airline. A 30,000mAh power bank is approximately 111 Watt-hours, which exceeds the standard 100Wh limit. While it is not strictly banned like larger batteries, you are required to ask for airline approval at the check-in counter to bring it on board, and it must be in your carry-on.
What is the largest power bank you can fly with?
Without needing to ask for special permission, the limit is 100Wh, which is roughly 27,000mAh. If you obtain airline approval, the absolute maximum capacity allowed on a passenger plane is 160Wh, which is approximately 43,000mAh.
What size power bank is ok for TSA?
TSA allows any power bank rated under 100 Watt-hours (roughly 27,000mAh) to pass through security without special declaration. These must be packed in carry-on bags only; they are never allowed in checked luggage.
How to check powerbank capacity?
The most reliable way is to check the printed specifications on the device's casing. Look for a number followed by "mAh" or "Wh." If only the milliampere-hours (mAh) are listed, use the formula (mAh × 3.7) ÷ 1000 to find the Watt-hours. If the label is faded, scratched off, or missing, do not bring it to the airport, as security agents cannot verify its safety and will likely confiscate it.
