Power banks are prohibited in checked luggage on US flights and must be carried in carry-on bags only.
Understanding Airline Regulations for Power Banks
Power banks have become essential travel companions, powering smartphones, tablets, and other gadgets on the go. However, their lithium-ion batteries pose safety concerns during flights. The US Department of Transportation (DOT) and the Federal Aviation Administration (FAA) have strict rules regarding the transport of lithium batteries, including power banks.
The primary concern is the risk of battery fires or thermal runaway incidents inside aircraft cargo holds. Lithium-ion batteries can catch fire if damaged or short-circuited, which is why airlines prohibit them in checked luggage. Instead, passengers are required to carry power banks in their carry-on baggage where any incident can be quickly detected and managed.
Why Are Power Banks Banned From Checked Luggage?
The cargo hold of an aircraft is inaccessible during flight, making it impossible to respond swiftly if a battery malfunctions. Lithium-ion batteries are classified as dangerous goods due to their flammable electrolyte and potential for overheating.
Several incidents worldwide have highlighted the dangers of lithium batteries igniting in checked baggage. This has led to international aviation bodies enforcing strict guidelines that forbid carrying spare lithium batteries or power banks in checked luggage.
In contrast, carry-on compartments are monitored by flight attendants and passengers, allowing for immediate action if a fire starts. This safety measure drastically reduces the risk of catastrophic events related to battery fires.
Official Guidelines from FAA and Airlines
The FAA clearly states that portable electronic devices containing lithium-ion batteries must be transported in the cabin. Most US airlines align with these regulations and explicitly ban power banks from checked bags.
Here’s a quick rundown:
- Power banks must be carried in carry-on baggage only.
- There are size limits on power bank capacity—usually up to 100Wh without airline approval.
- Power banks exceeding 100Wh but less than 160Wh require airline approval.
- Power banks over 160Wh are generally prohibited on passenger aircraft.
Ignoring these rules can lead to confiscation of your device at security checkpoints or even fines. Airlines also reserve the right to deny boarding if rules aren’t followed.
What About International Flights?
Most international aviation authorities follow similar guidelines as the FAA because they adhere to standards set by the International Civil Aviation Organization (ICAO). Still, it’s wise to check specific airline policies before traveling abroad since some carriers may have stricter rules or additional paperwork requirements for larger capacity power banks.
The Technical Side: Watt-Hours (Wh) Explained
Understanding watt-hours (Wh) helps you know if your power bank complies with airline limits. Watt-hours measure battery energy capacity and are calculated as:
Wh = (mAh × V) ÷ 1000
- mAh = milliamp hours (battery capacity)
- V = voltage
Most common power banks operate at about 3.7 volts.
For example:
- A 10,000mAh power bank at 3.7V has approximately 37Wh.
- A 20,000mAh power bank at 3.7V has approximately 74Wh.
This means most consumer-grade power banks fall under the standard allowance of under 100Wh and can be safely carried onboard without special approval.
Power Bank Capacity Limits Table
| Capacity Range (Watt-hours) | Airline Policy | Notes |
|---|---|---|
| <100 Wh | Allowed in carry-on baggage without restrictions | No airline approval needed; common sizes like 10,000–20,000mAh fit here |
| 100 Wh – 160 Wh | Allowed with airline approval only | Larger power banks; approval required prior to travel |
| >160 Wh | Prohibited on passenger aircraft | Usually reserved for industrial use; cannot be transported by passengers |
Packing Tips: How to Carry Your Power Bank Safely Onboard
Since you can’t pack a power bank in checked luggage on US flights, it’s important to follow best practices when carrying it onboard:
- Keep your power bank easily accessible: Security might ask you to remove it from your bag during screening.
- Avoid loose terminals: Cover exposed terminals with tape or keep them inside a protective case to prevent short circuits.
- Don’t overload your carry-on: Combine your electronics thoughtfully so you don’t exceed carry-on weight limits.
- Avoid damaged units: Don’t bring swollen or physically damaged power banks—they could pose fire risks and may be confiscated.
- No charging during takeoff/landing: Follow crew instructions about device usage during critical flight phases.
- Cord management: Keep cables neat and avoid tangled cords that could cause accidents when storing devices.
- No spare batteries inside checked bags: Even spare lithium batteries must stay out of checked luggage unless installed inside devices carried onboard.
- If unsure about capacity: Check manufacturer specs or use online calculators to determine your device’s watt-hour rating before packing.
The Consequences of Ignoring Rules: What Happens If You Pack A Power Bank In Checked Luggage?
Trying to sneak a power bank into checked luggage risks more than just losing your device:
If TSA discovers a prohibited battery during screening or inspection after check-in, they will likely confiscate it without compensation. You might also face delays while security investigates potential hazardous materials in your bag.
The airline may refuse boarding until you remove the item from checked baggage or transfer it into carry-on luggage if possible. In rare cases where dangerous goods cause incidents mid-flight, airlines face liability issues and regulatory penalties.
Avoiding these complications by following guidance saves time, money, and stress. Plus, being proactive about packing demonstrates respect for safety protocols that protect everyone onboard.
The Role of TSA Security Screening Agents
TSA agents are trained extensively on identifying hazardous materials including lithium batteries concealed inside bags. Their scanners detect suspicious items rapidly during routine inspections.
If you pack a prohibited item like a large capacity or loose battery inside checked luggage:
- TSA will flag it immediately;
- You’ll be asked questions about its contents;
- The device may be removed and destroyed for safety reasons;
- You could face additional scrutiny on future trips if violations repeat frequently.
Therefore, transparency is key—declare any unusual devices when asked at security checkpoints.
The Difference Between Carry-On and Checked Luggage Regulations for Electronics Batteries
Airlines classify batteries differently based on whether they’re installed inside devices or standalone spares:
- Batteries installed inside laptops, cameras, phones: Allowed both in carry-on and checked luggage because they’re secured within equipment designed to minimize risks.
- Spares like external power banks or extra lithium-ion cells: Must always stay in carry-on bags due to fire hazard potential if damaged during handling in cargo holds.
- Lithium-metal batteries: Also restricted similarly due to higher fire risks compared to lithium-ion types commonly found in consumer electronics.
This explains why “Can I Pack A Power Bank In My Checked Luggage In The USA?” is answered firmly with “No.” Even though some electronic devices with built-in batteries can go into checked baggage safely, loose external batteries cannot.
