The Transportation Security Administration (TSA) has introduced a significant update to its regulations, banning power banks and lithium-ion batteries from checked luggage. This change, driven by safety concerns, has caught many travelers off guard, especially with the busy summer travel season in full swing. If you’re planning a trip in 2025, understanding these new rules is crucial to avoid delays, fines, or confiscated items at the airport. This article breaks down the reasons behind the ban, what it means for travelers, and how to pack smart to stay compliant.
Why Are Power Banks Banned from Checked Luggage?
The TSA’s decision to prohibit power banks in checked luggage stems from the fire risks associated with lithium-ion batteries. These batteries, commonly found in portable chargers, can overheat, short-circuit, or ignite if damaged or improperly stored. In the cargo hold of an aircraft, a fire can spread rapidly and is challenging to control, posing a serious threat to passenger safety.
According to experts, the risk is significantly higher in checked luggage because these bags are stored in the cargo hold, where monitoring and extinguishing fires is more difficult. The Federal Aviation Administration (FAA) has also issued warnings about lithium-ion battery risks, prompting airlines like United to enforce similar restrictions for years. The TSA’s updated policy aligns with these safety concerns, ensuring that power banks are kept in carry-on luggage, where potential issues can be addressed more quickly.
The Science Behind Lithium-Ion Battery Risks
Lithium-ion batteries power many of our everyday devices, from smartphones to laptops. However, they can become unstable under certain conditions, such as physical damage, extreme temperatures, or manufacturing defects. When a battery short-circuits, it can generate enough heat to ignite nearby materials. In a confined space like a cargo hold, this could lead to catastrophic consequences. By requiring power banks to be carried in the cabin, the TSA ensures that any issues can be detected and managed by passengers or crew members.
What Does the Ban Mean for Travelers?
The TSA’s new rule means that all power banks and loose lithium-ion batteries must be packed in carry-on luggage. This applies to all commercial flights within, to, or from the United States. Travelers caught with power banks in checked bags may face delays at security checkpoints, confiscation of their devices, or even fines in some cases. To help you navigate this change, here’s a breakdown of what you need to know:
- Carry-On Only: Power banks must be packed in your carry-on bag or personal item, such as a backpack or purse. They are not allowed in checked luggage under any circumstances.
- Size Restrictions: The TSA allows power banks with a capacity of up to 100 watt-hours (Wh) in carry-on luggage without prior approval. Power banks between 100 and 160 Wh require airline approval, and those exceeding 160 Wh are prohibited.
- Proper Storage: Ensure your power bank is protected from damage. Use a case or sleeve to prevent short-circuiting and store it in a secure compartment of your carry-on bag.
- Airline Policies: Some airlines may have stricter rules than the TSA. Check with your carrier before packing to avoid surprises at the airport.

Other Devices Affected by the Ban
While the ban specifically targets power banks and loose lithium-ion batteries, other devices with built-in batteries, such as laptops, tablets, and cameras, are still permitted in both carry-on and checked luggage. However, the TSA advises travelers to keep these devices in carry-on bags whenever possible to reduce risks. E-cigarettes and vaping devices, which also use lithium-ion batteries, must also be carried in carry-on luggage, and their use is prohibited on board.
How to Pack Safely for Your Next Flight
Adapting to the TSA’s new rules doesn’t have to be complicated. Here are some practical tips to ensure a smooth travel experience:
- Check Your Luggage Before Packing: Before heading to the airport, inspect your checked bags to ensure no power banks or loose batteries are included. Double-check old bags, as power banks can sometimes be forgotten in side pockets.
- Choose TSA-Approved Power Banks: Opt for power banks that meet TSA guidelines (100 Wh or less) to avoid complications. Check the watt-hour rating on the device or its packaging.
- Stay Informed: Visit the TSA’s “What Can I Bring?” tool for a comprehensive list of permitted and prohibited items.
- Plan for Charging Needs: Since power banks must stay with you, consider bringing a compact charger for convenience. Avoid using public USB charging stations at airports, as they may pose cybersecurity risks, according to the FAA.
- Label Your Devices: Clearly mark your power banks with your name or contact information to avoid confusion if they’re removed during screening.
New TSA Technologies and Loosened Restrictions
While the power bank ban tightens rules for checked luggage, the TSA has also introduced new technologies and loosened some restrictions. Advanced computed tomography (CT) machines, now being rolled out at major airports, allow security officers to better evaluate the contents of carry-on bags. This has led to the approval of 11 new items for carry-on luggage, though the TSA has not specified what these items are. For the latest updates, check the TSA’s official news page.
Tips for Stress-Free Airport Security
Navigating airport security can be daunting, especially with new regulations in place. To make your experience as smooth as possible, consider these additional tips:
- Arrive Early: Give yourself extra time at the airport to account for potential delays during security screening.
- Organize Your Carry-On: Place power banks and other electronics in an easily accessible part of your bag to speed up the screening process.
- Stay Updated on Airline Rules: Airlines like United and Delta may have additional restrictions on batteries or electronic devices.
The TSA’s ban on power banks in checked luggage is a critical step toward ensuring air travel safety, driven by the fire risks posed by lithium-ion batteries. By packing power banks in your carry-on, choosing TSA-approved devices, and staying informed about airline policies, you can avoid disruptions and enjoy a stress-free travel experience. As airports adopt new technologies and regulations evolve, keeping up with the latest guidelines is essential for every traveler. Before your next trip, take a moment to review your packing list and consult reliable sources like the TSA and FAA websites to ensure compliance. Safe travels!
