Can I Bring a Power Bank on a Plane? 2025 Flight Rules mAh Limits

It’s undeniable that in today’s tech-driven world, carrying essential electronic devices like mobile phones or smartphones has become completely normal—almost everyone owns at least one. These days, smartphones can do everything from making calls to managing work. For those who focus more on productivity, devices like iPads or tablets have become powerful tools that can handle various tasks just as efficiently, often replacing bulkier laptops. As a result, one common issue most people face is battery drain after prolonged use. That’s where accessories like power banks—or portable chargers—come in handy.
A power bank is a compact, portable charging device that's easy to carry and quick to use. It allows you to recharge your devices on the go, helping you extend their battery life throughout the day. The higher the mAh (milliamp hours), the more times it can recharge your device—or be shared with others. However, when it comes to air travel, there are definitely rules regarding how you can carry a power bank onboard. That’s why Gother is here to answer one of the most frequently asked questions: “How many mAh can a power bank be to take on a plane?”—so you can prepare ahead of time and fly with peace of mind.

A power bank, or portable charger, is a device used to recharge electronic gadgets. Thanks to its compact size, it's easy to carry and can be used anytime, anywhere. That’s why many people keep one with them to recharge their devices while traveling—whether on a car trip or even on an airplane. However, bringing a power bank on board a flight is subject to certain regulations. According to the International Air Transport Association (IATA), there are specific rules about how many mAh (milliamp-hours) a power bank can have to be allowed on board. The power bank must meet quality standards, have a clear capacity label printed on the device, and indicate its exact mAh rating. The regulations are as follows:
 

• Power banks with a capacity below 20,000 mAh: Allowed on board with no limit on quantity.
• Power banks with a capacity between 20,000–32,000 mAh: Allowed on board, but limited to a maximum of 2 devices per passenger.
• Power banks with a capacity over 32,000 mAh: Not allowed on board under any circumstances, whether carried or checked in.

Items Allowed in Carry-On Baggage

• Mobile phones and tablets
• Liquids in containers not exceeding 100 ml
• Cameras
• Non-liquid cosmetics
• Non-liquid snacks
• Bags with a total weight not exceeding 7 kg

Items Not Allowed in Carry-On Baggage

• Liquids such as drinking water, cosmetics, or toiletries exceeding 100 ml
• Fresh food or strong-smelling items, including dry ice
• Large bags weighing more than 7 kg
• Large sports equipment or musical instruments
• Tripods
• Hazardous chemicals or toxic substances
• Flammable items
• Weapons or sharp objects. If carrying a licensed firearm, it must be disassembled and non-functional
• Venomous or dangerous animals
• Counterfeit or pirated goods
• Magnets

Aside from the frequently asked question about how many mAh a power bank can have to be brought on a plane, another popular question is whether you can check in a power bank in your luggage if it can’t be carried on board. The answer is simple: no, you cannot. Power banks must be carried in your hand luggage only, and only if their capacity does not exceed 32,000 mAh. If the power bank has a capacity of more than 32,000 mAh, it is strictly prohibited from being brought on board in any form—whether carried on or checked in.

Of course, bringing a power bank on a plane is easy—you just pack it in your bag, sling it over your shoulder, and board the aircraft. However, proper storage can make a big difference. Just like other electronic devices must be turned off before takeoff, a power bank also requires careful handling. Following correct packing and usage guidelines ensures a smooth, hassle-free journey from takeoff to landing.

What to Do Before Takeoff

Check the Condition of Your Power Bank

Now that we’ve covered all the details, here’s a quick summary: Power banks are allowed on planes, but only in your carry-on luggage. They are strictly prohibited from being stored in checked baggage under any circumstances. The allowed capacity (in mAh) is clearly defined, and if you plan to carry more than one power bank, the total capacity will determine how many you can bring. Additionally, your power bank should comply with international safety standards such as CE, UL, or RoHS. To make things even clearer, Gother has created a summary table to help you easily understand the rules at a glance.
