Knowing the rules before you travel can prevent unexpected baggage checks. During a past trip, security pulled a backpack aside after discovering five forgotten power banks inside. Although the inspection went smoothly after officers identified the items, the experience highlighted how easily certain electronics trigger security warnings.
Portable power banks and personal electronics like smartphones, tablets, laptops, and handheld gaming systems must travel in carry-on luggage. Checked baggage is not the place for these devices. Laptops should always be removed for scanning, and taking out other electronics can also prevent delays. Lithium battery regulations apply to both installed and uninstalled components, making advance preparation essential for a smooth airport experience.
Power Bank Rules and Watt-Hour Limits
Most portable power banks remain under the 100 watt-hour limit. Devices featuring built-in batteries, such as cameras, laptops, tablets, and smartwatches, must accompany passengers in the cabin. High-powered laptop power banks represent a potential exception, though many standard models like the 25K Anker Power Bank comply with regulations at 90Wh and carry flight-approved labels.
Travelers can verify power bank specifications by checking for watt-hour ratings or calculating them using the formula of milliamp-hours multiplied by voltage divided by 1,000. A 20,000mAh power bank operating at 3.7 volts equals 74Wh, remaining safely within allowed limits. Packaging frequently features a flight-approved label to provide additional clarity.
Lithium Batteries and Fire Hazards
Lithium batteries require cabin storage because overheating creates a potential fire risk. Lithium-ion batteries exceeding 100 watt-hours, including spare units or professional AV equipment, remain prohibited in checked bags. These items are permitted in carry-on luggage only under specific circumstances with airline approval, limited to two per person.
Non-rechargeable lithium metal batteries, such as standard AA batteries intended for toys, are permitted up to 2 grams of lithium content per battery. Keeping these items inside their original packaging minimizes security complications. Alternatively, purchasing them at the destination avoids travel restrictions entirely.
Vapes, E-Cigarettes, and Laser Pointers
Electronic cigarettes and vapes must travel exclusively in carry-on luggage and cannot go into checked bags. Security screening typically does not require removing them from bags, though placing them in bins can prevent potential alerts. Southwest Airlines restricts passengers to two units per person and explicitly prohibits charging or using them onboard.
Similar restrictions apply to gadgets like laser pointers. While federal rules generally approve them, specific carriers maintain stricter policies. Air Canada bans laser pointers in the cabin entirely, requiring them in checked luggage. Penlights and similar devices may also prompt manual inspection by security personnel.
Smart Luggage and Tracking Devices
Smart suitcases equipped with integrated chargers, charging ports, GPS trackers, or Bluetooth locks must follow standard lithium battery guidelines. Power sources must be removed before checking a bag to eliminate fire hazards. Removable integrated power banks facilitate this process easily.
Bags featuring non-removable batteries present complications at security checkpoints. Boarding permission depends on sizing requirements and the discretion of TSA agents and flight crews. Tracking devices must contain less than 0.3 grams of lithium metal or 2.7 Wh of lithium-ion. Apple AirTags comply with these standards because their CR2032 batteries contain under 0.1 grams of lithium and remain under 0.7 Wh.
Hoverboards and Ride-On Bags
Passenger policies regarding hoverboards and ride-on luggage vary significantly by airline. American Airlines restricts smart ride-on bags, while Delta Air Lines prohibits motorized rideable suitcases. Air Canada bans electric skateboards, airwheels, mini Segways, balance wheels, battery-assisted bikes, and electric scooters. Hoverboards remain strictly prohibited on commercial flights due to safety considerations.
Electric Toothbrushes and Personal Care Gadgets
Electric toothbrushes containing batteries must travel in carry-on luggage. Passengers can utilize these devices during long flights or airport layovers. However, failing to power down an electric toothbrush or portable massager can cause accidental activation and buzzing noises that prompt TSA investigations. Leaving these items inside the bag is acceptable as long as they remain completely turned off.
Smartphones and Computers at Security Checkpoints
The Samsung Galaxy Note 7 launched in 2016 remains the sole smartphone entirely banned from commercial flights due to verified fire hazards. All other smartphones must travel in the cabin. TSA agents generally require passengers to place phones, tablets, laptops, and portable gaming systems into separate bins for scanning, though alternative instructions should be followed if agents advise leaving items inside bags. A 2014 ruling permits security personnel to request that devices be powered on to verify functionality, underscoring the importance of maintaining adequate battery life.
Complying with TSA screening requests ensures a faster security process. Travelers can minimize delays by packing restricted tech correctly and avoiding items that trigger red flags during screening.
