If you’re wondering, Can You Bring a Power Bank on a Plane, the answer is yes—provided you follow TSA and airline safety rules. Portable chargers have become essential travel accessories, helping passengers keep phones, tablets, laptops, cameras, and other devices powered throughout long trips.
However, because power banks contain lithium-ion batteries, airlines have strict safety regulations regarding how they must be packed. Knowing these rules before arriving at the airport can help you avoid delays, confiscation, or unexpected problems during security screening.
This complete guide explains everything U.S. travelers need to know in 2026, including TSA regulations, FAA battery limits, airline policies, international travel considerations, and practical packing tips.
Quick Answer
Yes, you can bring a power bank on a plane—but only in your carry-on bag. According to TSA and FAA regulations, portable chargers that use lithium-ion batteries are not allowed in checked luggage because they pose a potential fire risk. Most travelers can carry power banks up to 100Wh without airline approval. Batteries between 100Wh and 160Wh usually require airline permission, while those over 160Wh are generally prohibited on passenger flights.
Why Airlines Regulate Power Banks
Power banks contain rechargeable lithium-ion batteries. While these batteries are generally safe, damaged or defective batteries can occasionally overheat.
This overheating process is called thermal runaway, which can cause smoke, fire, or extreme heat. Although these incidents are rare, airlines take them seriously because fires inside an aircraft cargo hold are much harder to detect and extinguish than fires inside the passenger cabin.
For this reason, aviation authorities require passengers to keep power banks in their carry-on baggage where cabin crews can quickly respond if a battery malfunctions.
Main Reasons for These Rules
- Prevent lithium battery fires
- Allow quick response to overheating
- Protect passengers and crew
- Reduce cargo fire risks
- Improve overall flight safety
2026 TSA Rules for Power Banks
The Transportation Security Administration (TSA) allows passengers to carry portable chargers that contain lithium batteries, but there are important restrictions.
TSA Rules at a Glance
| Rule | Allowed? |
| Carry power bank in carry-on | ✅ Yes |
| Pack in checked luggage | ❌ No |
| Charge devices during flight | ✅ Usually Yes |
| Loose lithium batteries in checked bag | ❌ No |
| Multiple power banks | ✅ Usually Allowed (reasonable quantity) |
Carry-On Bags
Power banks should always remain inside your carry-on luggage or personal item.
Examples include:
- Backpack
- Laptop bag
- Purse
- Camera bag
- Small travel bag
Keeping the battery with you allows flight attendants to respond quickly if there is any sign of overheating.
Checked Baggage
Never place a loose power bank inside checked luggage.
Airport security may:
- Remove it
- Delay your baggage
- Confiscate the battery
- Require you to repack your luggage
Even if your checked suitcase contains electronic devices, removable power banks should always be carried separately in the cabin.
FAA Lithium Battery Guidelines
The Federal Aviation Administration (FAA) provides additional guidance on lithium batteries.
The key factor isn’t the battery’s physical size—it’s its watt-hour (Wh) rating.
Most manufacturers print this information directly on the power bank.
If it isn’t listed, you can calculate it:
Wh = (Voltage × mAh) ÷ 1000
Example
A power bank rated:
- 20,000mAh
- 5V
Calculation:
20,000 × 5 ÷ 1000
= 100Wh
That means it’s generally allowed without airline approval.
FAA Battery Limits
| Battery Capacity | Allowed? |
| Up to 100Wh | ✅ Yes |
| 101–160Wh | ✅ Airline approval required |
| Over 160Wh | ❌ Not allowed for passengers |
These limits apply to most commercial airlines operating in the United States.
Why the 100Wh Limit?
Research shows smaller lithium batteries present significantly lower fire risks than larger, high-capacity batteries.
Most common portable chargers sold for smartphones fall below the 100Wh limit, making them suitable for air travel.
Carry-On vs. Checked Bags: Where Should You Pack Your Power Bank?
One of the most common travel questions is whether a power bank belongs in your carry-on or checked luggage. The answer is simple: always pack it in your carry-on bag.
Lithium-ion batteries can overheat if they are damaged or have a manufacturing defect. If this happens in the aircraft cabin, flight attendants can quickly respond. If the same incident occurs in the cargo hold, it is much harder to detect and manage.
Carry-On vs. Checked Baggage Comparison
| Feature | Carry-On Bag | Checked Bag |
| Power bank allowed | ✅ Yes | ❌ No |
| TSA approval | ✅ Yes | ❌ Not allowed |
| Cabin crew can respond to overheating | ✅ Yes | ❌ No |
| Recommended by FAA | ✅ Yes | ❌ No |
| Risk of confiscation | Low | High |
Best Practice
Keep your power bank in:
- Your backpack
- Laptop bag
- Purse
- Personal item under the seat
Avoid placing it inside checked baggage, even if it is switched off.
How Many Power Banks Can You Bring on a Plane?
Most airlines allow passengers to carry more than one power bank for personal use.
However, there are limits designed to prevent passengers from transporting large numbers of lithium batteries.
General Guidelines
