TSA Alerts Flyers: Five Everyday Devices Likely to Prompt Extra Screening

The Transportation Security Administration has highlighted five commonplace electronic gadgets that are prone to trigger additional checks at airport security lines, underscoring that even ordinary items can cause delays for passengers.

Items most often singled out include spare lithium‑ion batteries, high‑capacity power banks, e‑cigarettes or vaping pens, external hard drives exceeding a few terabytes, and wearable technology like smart watches with removable batteries. Each of these possesses traits that raise safety or security alarms for screeners.

Lithium‑ion cells are valued for their high energy density but also present a fire risk if they short‑circuit or get damaged. Consequently, the TSA mandates that loose batteries remain in their original packaging or be otherwise insulated, and it caps the watt‑hour rating of power banks allowed on board. Vaping devices, though widely used, are treated as electronic cigarettes and must be stored in a carry‑on bag, with liquid refills screened separately.

External hard drives, particularly those with multiple platters or large storage capacities, can look suspicious on X‑ray machines because of their dense metal parts. Wearable gadgets with removable batteries fall under the same rules as spare batteries: the battery must be detached from the device and shielded from accidental contact with metal objects.

Travelers can lower the chance of a secondary inspection by consolidating batteries, using protective battery cases, and making sure all devices are completely powered off before reaching the checkpoint. Packing items in clear, resealable bags and having documentation—such as a battery specification sheet—readily available can also help officers verify compliance swiftly.

This increased scrutiny of electronics mirrors a wider trend: as personal technology becomes more woven into everyday life, the volume of items moving through security checkpoints has risen. While the TSA does not release precise statistics, industry watchers note a steady climb in incidents involving overheating batteries and attempts to hide prohibited items inside electronic housings.

Passengers who face extra screening should anticipate a short pause while officers perform a manual check or employ handheld detectors. In most instances, this adds only a few minutes to the overall screening process, though repeated triggers can lengthen lines during busy travel periods.

Looking forward, the agency has indicated it will keep updating its guidelines as battery technology advances. Travelers are urged to consult the latest TSA recommendations on the official website before each trip to confirm their gadgets meet current standards and to avoid unnecessary delays.
