Can I Bring a Bulletproof Backpack on a Plane?
Yes. Bulletproof backpacks and ballistic backpack panels are generally permitted in both carry-on and checked baggage. TSA and airlines allow ballistic protection products, including backpacks with integrated ballistic panels and removable backpack armor inserts.
At airport security checkpoints, the final determination regarding any item rests with the TSA officer on duty.
Travel Tips
• Inform the TSA officer if your backpack contains ballistic protection panels.
• Backpacks with removable ballistic inserts may be easier to inspect during security screening.
• If your backpack contains steel or ceramic armor plates, consider removing them and placing them in a separate screening bin to help reduce delays during the X-ray process.
• Ballistic backpack panels provide an easy way to add protection to an existing backpack without purchasing a dedicated ballistic backpack.
• International travelers should verify destination country laws before departure, as some countries restrict or prohibit civilian ownership of body armor and ballistic protection products.

Can I Bring a Stun Gun or TASER Device on a Plane?
Stun guns and TASER devices are prohibited in carry-on baggage and may only be transported in checked baggage when permitted by TSA and your airline.
Only devices with removable batteries may be transported in checked baggage. The batteries must be removed from the device and carried separately by the passenger in their carry-on luggage in accordance with applicable airline and battery transportation requirements.
Devices with non-removable or built-in batteries are prohibited and may not be transported in checked baggage.
Stun guns and TASER devices are generally not permitted on international flights and may be restricted or prohibited by foreign governments, airlines, and destination countries.
Before traveling, always verify:
• TSA regulations
• Airline policies
• Battery transportation requirements
• State and local laws
• Destination laws and restrictions
Travelers should ensure their device is secured against accidental discharge and confirm whether declaration at check-in is required by their airline.

Can I Bring Pepper Spray on a Plane?
The TSA and FAA generally permit one small container of pepper spray up to 4 fl. oz. / 118 ml in checked baggage only. The container must have an active safety mechanism to prevent accidental discharge and may not contain more than 2% by mass of CS or CN tear gas.
Pepper spray is strictly prohibited in carry-on baggage.
Travelers should always check with their airline before departure, as many airlines maintain stricter policies than TSA regulations and may prohibit pepper spray entirely, even in checked baggage. Airline policies can vary and may change without notice.
If your airline permits pepper spray in checked baggage, consider purchasing a pepper spray that is factory sealed inside a hard-plastic clamshell package. This additional layer of protection may help prevent accidental discharge or leakage during transit. SDP Inc. offers select pepper spray products packaged in sealed hard-plastic clamshells specifically designed for secure storage and transport.
Pepper spray is generally prohibited on most international flights and may be restricted or illegal in many foreign countries.
Before traveling, always verify:
• TSA regulations
• Airline policies
• Pepper spray size restrictions
• State and local laws
• Destination laws and restrictions
────────────────────────────
Can I Bring a Personal Safety Alarm on a Plane?
Yes. Personal safety alarms are generally permitted in both carry-on and checked baggage. TSA allows standard personal alarms, including many keychain-style alarms commonly used for personal safety and emergency situations.
Because personal safety alarms are designed to emit an extremely loud sound, travelers should pack them securely to help prevent accidental activation during travel. Avoid attaching alarms to the outside of bags where they could become snagged and unintentionally trigger the alarm.
Battery Considerations
Most personal safety alarms are battery-powered and permitted for air travel. If your alarm contains lithium batteries, travelers should verify that the batteries comply with current TSA and airline battery requirements.
International Travel
While personal safety alarms are generally permitted within the United States, travelers should verify local laws and airline policies when traveling internationally, as regulations may vary by country.
Before traveling, always verify:
• TSA regulations
• Airline policies
• Battery requirements
• Destination laws and restrictions
────────────────────────────
Can I Bring a Self-Defense Keychain on a Plane?
Generally, most self-defense keychains are prohibited in carry-on baggage because they may be considered weapons or security risks. This includes many keychains that feature striking points, spikes, sharp edges, impact tools, or brass knuckle-style designs.
Many self-defense keychains may be transported in checked baggage; however, travelers should verify current TSA regulations before departure.
Because self-defense keychains vary significantly in design and function, TSA officers have the final authority to determine whether an item is permitted through the security checkpoint.
Examples of self-defense keychains that may be restricted or prohibited in carry-on baggage include:
• Kubotans
• Tactical spikes
• Brass knuckle-style keychains
• Impact tools
• Sharp-edged defensive keychains
Travelers should always verify:
• TSA regulations
• Airline policies
• State and local laws
• Destination laws and restrictions
────────────────────────────
Can I Bring Flashlights on a Plane?
Yes. Flashlights are generally permitted on airplanes; however, restrictions may apply depending on the flashlight's size, design, and battery type.
Most standard flashlights are permitted in carry-on baggage. Flashlights equipped with aggressive strike bezels, glass breakers, or other tactical features may be treated as potential weapons by TSA officers and could be prohibited from carry-on baggage.
Flashlights powered by lithium-ion batteries are generally best transported in carry-on baggage. If checking a flashlight that uses removable lithium batteries, travelers should verify current TSA and airline requirements regarding battery transportation.
Before traveling, always verify:
• TSA regulations
• Airline policies
• Battery transportation requirements
• Destination laws and restrictions
────────────────────────────
Can I Bring Emergency Food on a Plane?
Yes. Most emergency food products, freeze-dried meals, dehydrated foods, energy bars, trail mixes, and other shelf-stable food items are permitted in both carry-on and checked baggage.
Most solid food products are permitted through airport security, including freeze-dried meals, emergency food pouches, energy bars, trail mix, crackers, and similar shelf-stable foods.
Food products that can be spread, poured, pumped, sprayed, or otherwise classified as liquids or gels may be subject to TSA liquid restrictions.
Freeze-dried and dehydrated emergency food products are generally permitted because they contain little or no liquid, making them ideal for travel, camping, and emergency preparedness.
International travelers should be aware that customs and agricultural regulations are separate from TSA regulations and may restrict certain food products.
Before traveling, always verify:
• TSA regulations
• Airline policies
• Destination country restrictions
• Customs and agricultural regulations
────────────────────────────
Can I Bring Power Banks on a Plane?
Yes. Power banks are generally permitted on airplanes; however, they must be transported in carry-on baggage and are prohibited in checked baggage because they contain lithium-ion batteries.
Most power banks with a capacity of 100 watt-hours (Wh) or less are permitted in carry-on baggage without prior airline approval. Power banks exceeding 100 Wh may require airline authorization, while units exceeding 160 Wh are generally prohibited.
Travelers should ensure the battery capacity is clearly marked on the device and protect the terminals from accidental short circuits during travel.
Many airlines allow power banks to be used for charging electronic devices during flight, although individual airline restrictions may vary.
Before traveling, always verify:
• TSA regulations
• Airline policies
• Battery capacity restrictions
• Destination laws and restrictions
• International travel requirements

Alternative Travel Option: Ship Products to Your Destination
Depending on the product and destination, some travelers may choose to ship personal safety products, self-defense devices, emergency preparedness supplies, or other travel-related items directly to their destination rather than transport them during air travel.
Shipping may help avoid certain airline restrictions, baggage limitations, and transportation requirements that can apply to products such as pepper spray, stun guns, TASER devices, batteries, and other regulated items.
Before shipping any product, always verify:
• State and local laws
• Destination laws and restrictions
• Hotel, resort, campground, or receiving location policies
• Carrier shipping requirements
• Product-specific regulations
Travelers are responsible for ensuring that any product shipped to a destination is legal to possess, receive, and use at that location.
Important: Shipping regulations may differ from TSA and airline regulations. Always verify current requirements before shipping any self-defense, safety, or preparedness product.
