Yes, you can carry a power bank in your hand luggage in the USA, but it must comply with airline and TSA regulations regarding capacity and usage.
Understanding Power Bank Regulations for Air Travel in the USA
Carrying a power bank on a flight within or departing from the USA is generally allowed, but there are strict rules to ensure safety. The Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA) have set clear guidelines about power banks due to their lithium-ion batteries. These batteries can pose fire risks if damaged or improperly handled.
The key factor here is the battery capacity, measured in watt-hours (Wh). Most airlines restrict power banks based on this rating. Typically, power banks with a capacity of up to 100Wh are allowed in carry-on luggage without prior approval. Those between 100Wh and 160Wh may require airline approval, while anything above 160Wh is usually prohibited.
This means that before packing your power bank, you need to check the label or product specifications carefully. The watt-hour rating is often printed on the device or its packaging. If you only see milliampere-hours (mAh), you can convert it to Wh using this formula:
Wh = (mAh × Voltage) ÷ 1000. Most power banks operate at 3.7 volts.
Why Are Power Banks Restricted in Checked Luggage?
Power banks are forbidden in checked baggage primarily because lithium-ion batteries can ignite if they short circuit or get damaged during flight. Inside the cargo hold, fires are harder to detect and control compared to the passenger cabin. That’s why airlines insist on carrying them only in hand luggage where crew members can quickly respond if an incident occurs.
Putting your power bank in your carry-on also allows security personnel to inspect it if needed. Attempting to check it could lead to confiscation or delays.
Airline Policies: What You Should Know Before Flying
While TSA and FAA provide overarching rules, individual airlines may have slightly different policies regarding power banks. It’s always wise to check your airline’s website before traveling.
Here’s what most airlines generally require:
- Capacity limit: Power banks must be below 100Wh without special permission.
- Quantity limit: Usually one or two units per passenger.
- Packaging: Devices should be protected from short circuits — for example, by keeping them in their original packaging or covering terminals with tape.
- Usage: Power banks should not be used while charging other devices during takeoff and landing.
Some airlines may require passengers carrying larger capacity batteries (between 100-160Wh) to notify them ahead of time and get approval. Exceeding these limits often means you cannot bring the device onboard at all.
The Role of TSA Security Checks
During security screening at airports, TSA agents may ask you to remove your power bank from your bag for separate inspection. They’ll verify its size and condition. Any sign of damage or non-compliance could result in confiscation.
To avoid hassle:
- Keep your power bank easily accessible.
- Carry proof of its specifications if possible.
- Avoid homemade or modified devices that raise suspicion.
The Science Behind Lithium-Ion Battery Restrictions
Lithium-ion batteries pack a lot of energy into a small space, which makes them ideal for portable electronics like smartphones and power banks. However, this density comes with risks.
If a battery gets punctured, crushed, or overheats, it can enter what’s called “thermal runaway.” This process causes rapid temperature increase and potentially fires or explosions. On airplanes, such an event could be catastrophic.
That’s why regulatory bodies worldwide strictly control how lithium-ion batteries are transported by air — especially those not installed inside devices but carried separately as spare batteries or power banks.
Battery Capacity Explained
Watt-hour (Wh) rating tells you how much energy a battery stores. It combines voltage and current capacity into one number:
| Capacity (mAh) | Voltage (V) | Watt-Hours (Wh) |
|---|---|---|
| 10,000 mAh | 3.7 V | (10000 × 3.7) ÷ 1000 = 37 Wh |
| 20,000 mAh | 3.7 V | (20000 × 3.7) ÷ 1000 = 74 Wh |
| 30,000 mAh | 3.7 V | (30000 × 3.7) ÷ 1000 = 111 Wh* |
*Note: A power bank with over 100Wh but less than 160Wh requires airline approval before flying.
Knowing this helps travelers pick suitable devices that won’t cause problems at security checkpoints.
Packing Tips for Your Power Bank in Hand Luggage
Packing your power bank smartly can save time and stress at airport security:
- Avoid loose cables: Keep charging cables organized and separate from the battery itself.
- Cushion your device: Place the power bank inside a padded pocket or case to protect against knocks.
- Avoid overpacking: Keep hand luggage light so security checks move quickly.
- TSA-friendly placement: Put your power bank near the top of your bag for easy removal when requested.
- No damaged batteries: If your device shows signs of swelling or damage, don’t bring it onboard—it could be confiscated for safety reasons.
The Importance of Label Visibility
Airline staff often check the label showing watt-hour ratings during inspections. If it’s faded or missing, they might ask questions or refuse boarding with that device.
If you bought an unbranded product without proper labels, consider carrying documentation such as receipts or manufacturer info proving compliance.
The Consequences of Not Following Rules
Ignoring regulations about carrying a power bank can lead to serious consequences:
- Your device might get confiscated permanently at security checkpoints.
- You could face delays while airport staff investigate suspicious items.
- A rare but possible safety incident might affect other passengers’ wellbeing.
- You risk fines if caught deliberately violating federal transport laws.
It pays off big time to double-check rules before flying rather than face headaches later on.

Frequently Asked Questions
Can I put a power bank in my hand luggage in the USA?
Yes, you can carry a power bank in your hand luggage in the USA as long as it complies with TSA and airline regulations. Power banks up to 100Wh are generally allowed without approval, while those between 100Wh and 160Wh may require airline permission.
What are the restrictions for putting a power bank in hand luggage in the USA?
The main restrictions involve the battery capacity and quantity. Power banks over 160Wh are prohibited, and usually only one or two units per passenger are allowed. Devices must be protected against short circuits, such as by taping terminals or keeping them in original packaging.
Why can’t I put a power bank in checked luggage in the USA?
Power banks are banned from checked luggage because lithium-ion batteries pose fire risks if damaged. Fires in the cargo hold are harder to detect and control, so airlines require power banks to be carried in hand luggage for safety reasons.
Do airline policies differ on putting a power bank in hand luggage in the USA?
While TSA and FAA set general rules, individual airlines may have slightly different policies regarding power banks. It’s best to check your airline’s website before flying to confirm their specific limits and requirements for carrying power banks.
How do I know if my power bank can be put in hand luggage in the USA?
Check the watt-hour (Wh) rating on your power bank or packaging. If only milliampere-hours (mAh) is listed, convert it using Wh = (mAh × Voltage) ÷ 1000, with most devices at 3.7 volts. Ensure it’s below 100Wh or seek airline approval if higher but under 160Wh.
Can I Put A Power Bank In My Hand Luggage In The USA? Final Thoughts
The answer is yes—you absolutely can carry a power bank in your hand luggage when flying within or from the USA—but only if it meets strict safety criteria laid out by TSA and FAA regulations along with individual airline policies.
Checking the watt-hour rating is crucial because it determines whether your device needs special approval or must stay behind altogether. Keeping devices accessible during security screening expedites inspection while protecting yourself from potential confiscation headaches.
Remember these essentials:
- Batteries under 100Wh travel freely; between 100-160Wh need approval; above 160Wh are banned onboard.
- Your power bank must never go into checked baggage due to fire risks associated with lithium-ion cells.
- Packing smartly—protecting terminals and labeling clearly—makes passing through security hassle-free.
- You’re responsible for abiding by both federal rules and specific airline requirements before boarding flights in the USA.
Travelers who prepare properly enjoy peace of mind knowing their essential gadgets will stay safe—and legal—throughout their journey.
