Keep Battery Pack in your carry-on so it stays safe, protected and within reach during the flight. Avoid checking high-value personal belongings.
Step-by-step packing instructions for Battery Pack
- 1Verify battery specifications for battery pack. Spare lithium-ion batteries and external power banks must stay in carry-on luggage — they are prohibited in checked bags.
- 2Ensure the battery pack power switch or heating element is fully off and safety-locked before placing it in your bag.
- 3Protect exposed terminals on spare batteries by covering contacts with tape or storing them in individual plastic pouches.
- 4Be prepared to remove large electronics (larger than a mobile phone) from your bag to lay them flat in a TSA screening tray.
- 5Store delicate screens and components inside a padded sleeve to protect them from impact during boarding and overhead-bin loading.
TSA security screening procedure
During security screening for battery pack, any device larger than a standard smartphone (such as laptops, tablets, or large camera equipment) must be removed from your carry-on luggage and placed in a dedicated screening bin with nothing underneath or on top. Power banks, spare lithium-ion batteries, and rechargeable devices must remain in your carry-on luggage and are strictly forbidden in checked baggage due to FAA cargo fire safety protocols. Turn off high-capacity battery units to prevent accidental activation during flight.
Federal aviation & hazmat regulations
Under Federal Aviation Administration (FAA) HazMat safety regulations (49 CFR § 175.10(a)(18)) and IATA Dangerous Goods Regulations, lithium-ion batteries powering battery pack are capped at 100 Watt-hours (Wh) per battery for standard carry-on. Spare batteries between 100 Wh and 160 Wh require explicit airline approval. Uninstalled lithium batteries are strictly prohibited in checked cargo holds because cargo fires involving lithium chemistries cannot be easily extinguished in flight.
Airline & international rule variations
While TSA establishes baseline security screening at U.S. airports, individual airlines reserve the right to enforce more stringent baggage policies for battery pack. Legacy U.S. carriers like Delta, United, and American Airlines generally align directly with TSA standards. However, ultra-low-cost carriers (such as Spirit or Frontier) and international airlines (including Ryanair, Lufthansa, and Emirates) strictly enforce cabin bag dimensions and weight limits (typically 7 kg to 10 kg total carry-on allowance). If traveling internationally, foreign aviation authorities like EASA (European Union) or CAA (United Kingdom) may have additional custom rules regarding electronics items.

Exceptions & special cases
Always consult with your airline or the TSA directly if you believe you qualify for a special exception for carrying battery pack.
International considerations
When flying internationally, you must comply not only with U.S. TSA regulations but also with the aviation security rules of your destination country and any transit hubs. For battery pack, policies can vary significantly in regions like the European Union (governed by EASA) or the United Kingdom (CAA). Some countries impose stricter volume limits on liquids, absolute bans on specific electronics, or rigorous customs declarations for items in the Electronics category. Always check the official customs and aviation authority website of your arrival country before packing this item.
Alternative options
For travelers looking to optimize their packing space, consider multi-purpose alternatives to battery pack. Travel-specific versions are often lighter, more compact, and explicitly designed to meet both TSA and international aviation standards seamlessly.
