Are Power Banks Allowed on Planes? Airline Safety Rules and Regulations

Not all planes have USB ports or power outlets in every seat. So, can you bring a power bank on a plane? The short answer is: yes — but with a few important rules.

Power banks are now our go-to travel companions that we simply can't leave home without. Whether you're flying domestically for a quick weekend getaway or traveling around the world, having a little extra power for your phone or tablet means one less thing to worry about. Before you throw a power bank in your bag, however, there are a few airline rules and safety tips to keep in mind.

Traveling with Power Banks: What You Need to Know

TSA and International Guidelines

When it comes to flying with power banks, there are some basic principles that almost all airlines and aviation authorities adhere to. In the case of air travel, the main worry for both airlines and aviation authorities is the safety risk associated with the lithium batteries contained in power banks. Under certain conditions, lithium batteries can overheat, catch on fire, or even explode, and this is why there are strict rules in place.

1. Capacity Limits

At the heart of these safety rules is a number you might not check often — watt-hours (Wh). While most people are familiar with milliampere-hours (mAh), airlines and aviation authorities like the TSA (Transportation Security Administration), FAA (Federal Aviation Administration), EASA (European Union Aviation Safety Agency), and ICAO (International Civil Aviation Organization) actually use Wh to determine whether your power bank is safe to bring on board. The general rule of thumb is that the lower the Wh rating, the safer the battery is considered to be for air travel.

Normally, power banks under 100Wh are good to go on most flights and don't require any airline approval. This includes the vast majority of models used to charge phones, tablets, and other electronic devices.

If your power bank falls between 100Wh and 160Wh, you're still allowed to bring it, but you'll need to get prior approval from the airline.

Anything over 160Wh? Unfortunately, that's a no-go. These are considered too risky for air travel and are not allowed on flights.

2. Carry-on Baggage Only

Based on TSA, FAA, and EASA guidelines, power banks must be packed in your carry-on baggage — never in checked baggage. This rule exists because lithium batteries can pose a fire risk if they malfunction or overheat, and it's much safer to manage that risk in the cabin where it can be addressed quickly.

If a power bank is found in a checked bag, it may be removed by security. So, avoid the hassle, always tuck your power bank into your carry-on, and you're good to go.

3. Quantity Caps

According to TSA and FAA regulations, there's no set limit on the number of power banks under 100Wh, as long as they are for personal use. That means you can bring multiple smaller power banks in your carry-on — perfect for frequent travelers or families sharing devices.

If you're traveling with larger power banks (between 101Wh and 160Wh), however, you can only bring up to two, and only with airline approval. This limit helps minimize potential safety risks while still giving you flexibility for extended travel needs.

Airline-Specific Rules and Limits

While TSA, FAA, ICAO, and EASA regulations provide a general framework, individual airlines may enforce additional rules. So, it's always a smart idea to double-check before your trip. Here's a quick look at what some major airlines say about bringing power banks on board:

American Airlines

• Power banks must be carried in your carry-on bag.

• Devices over 160Wh are prohibited.

• All power banks should be for personal use only.

Delta Air Lines

• Power banks under 100Wh are allowed without restrictions.

• Power banks between 101Wh and 160Wh require airline approval.

Emirates

•  Power banks are permitted in carry-on baggage only.

•  Must be for individual use, not resale.

•  You may be asked to keep the power bank switched off during the flight.

British Airways

• Allows up to four spare batteries (including power banks) under 100Wh.

• Must be packed in your carry-on and protected from short-circuiting.

• Use during flight may be restricted based on crew instructions.

Pre-Flight Checklist: 5 Tips for Traveling with Power Banks

Now that you know the rules, here's how to prep like a pro.

1. Check Your Power Bank's Specs

Before you even think about packing your power bank, flip it over and look for the label. You'll want to find the watt-hours (Wh) rating. If it's listed in mAh and volts, you can convert it using the formula: Wh = (mAh × V) / 1000. Make sure it's under 100Wh to avoid needing airline approval. Anything over 160Wh is a no-go. Plus, don't forget to check for visible safety certifications, like CE, FCC, or UL, for extra peace of mind.

2. Pack Strategically

This one is simple but critical: power banks must go in your carry-on bag, never in checked luggage. Store it somewhere easy to reach, like an outer pocket or tech organizer, especially if TSA or airport security needs to take a closer look. Keeping it accessible also makes it easier to charge your devices on the go.

3. Inspect Your Power Bank

Do a quick visual inspection before your trip. Cracked casing, swelling, strange smells, or ports that no longer fit snugly are all red flags you should pay attention to. If your power bank looks damaged or isn't working like it used to, it's better to leave it behind than risk carrying it with you.

4. Double-Check Airline Rules

As mentioned above, while TSA, FAA, and ICAO offer general guidelines, airlines can — and often do — have their own rules on power banks. Some restrict the number of power banks you can bring, while others may not allow their use in-flight.

5. Prep Your Power Bank

Give your power bank a partial charge before you fly — around 60-80% is ideal. A full charge can increase the risk of overheating, especially in fluctuating cabin temperatures. And, make sure your power bank is turned off before boarding.

If you stick to these simple tips, you'll save yourself a lot of headaches at the airport. You will get through security faster, and have peace of mind knowing your power bank is safely protected and ready to rock.

FAQs

1. Where should I pack my power bank?

Always pack your power bank in your carry-on bag. This is because they contain lithium batteries and can pose fire hazards if stored in the cargo hold. Make sure your power bank is stored properly to avoid short circuits.

2. Can I use a power bank on a plane?

Yes — but there are some limitations. While most airlines allow the use of power banks during flight, many are becoming stricter on when and how they should be used. In general, you may be permitted to use a power bank once you are cruising. However, this may change if you take off, land, or when the seatbelt sign is turned on. Some airlines may even prohibit the use of power banks during the entire flight. So, always double-check your airline's regulations before you fly.

3. Are there limits on the number of power banks I can carry?

Yes, there are restrictions, especially for those with a higher capacity. If your power banks are under 100Wh, you can usually bring more than one without special approval (as long as they’re for personal use). For power banks between 100Wh and 160Wh, you're generally permitted 2, but airline approval is needed. It’s always a good idea to check beforehand.

4. What happens if my power bank exceeds 100Wh?

The maximum capacity you can bring without special approval is 100Wh. With airline approval, you can bring power banks up to 160Wh — but that's usually the limit. Anything above 160Wh is not allowed. To stay worry-free, choose a power bank that clearly displays its watt-hour rating and falls within these limits.
