Tsa vape rules

According to the regulations of the Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA), you can carry electronic cigarettes on board, but you must strictly follow the following rules; otherwise, the devices may be confiscated and you may face penalties.

✈️ Key rules: Must be carried on person
Prohibited from being checked: All electronic cigarette devices (including disposable, refillable, and main units) and spare lithium batteries are strictly prohibited from being placed in checked luggage. Because lithium batteries catching fire in the cargo hold is difficult to control and poses serious safety hazards.

Must be carried on person: The devices must be placed in your carry-on luggage or in your pocket.

Battery restrictions: Power has an upper limit
Power limit: The rated energy of all lithium batteries (lithium-ion or lithium-metal) must not exceed 100 Wh. The capacity of ordinary electronic cigarettes' batteries is usually much lower than this (for example, a 1000mAh battery is approximately 3.7 Wh).

Backup battery protection: The backup batteries must be insulated to prevent short circuits, such as placing the batteries in their original packaging, a dedicated battery box, or sealing the metal contacts with insulating tape.

E-liquid restrictions: Follow liquid regulations
Carried on person: Each bottle of e-liquid must not exceed 100 milliliters (3.4 ounces) and must be placed in a transparent 1-quart (about 946 milliliters) sealed plastic bag.

Can be checked: E-liquid bottles without batteries can be placed in checked luggage.

Packing and security check advice
Prevent accidental activation: Make sure to turn off the device power or lock the buttons to prevent the heating element from accidentally starting and causing danger.

Separate for inspection: During security checks, usually the electronic cigarette devices and e-liquid bottles need to be taken out of the bag and inspected separately along with laptops and other items.

Note "Gate-Check": If you are required to check your carry-on luggage at the boarding gate (Gate-check), be sure to remove all electronic cigarettes and spare batteries from the bag in advance.

Prohibited behavior on board
Prohibited use: Electronic cigarettes are prohibited in any place on the plane (seats, aisles, bathrooms). Smoke detectors in the cabin are very sensitive and triggering an alarm will result in severe penalties.

Prohibited charging: Charging electronic cigarettes or batteries through the onboard USB interface or power sockets is prohibited during the flight.

Special attention for international flights
Destination regulations: Even if TSA in the US allows carrying, your destination country or region may have stricter or completely prohibited regulations. For example, Singapore, India, Thailand, Qatar, etc. have strict restrictions or even bans on electronic cigarettes.

Departure regulations: State and local regulations in the US vary. For example, airports in California, New York State, etc. may prohibit the use of electronic cigarettes.

Summary
As long as you remember the core principle of "Only carry on person, not checked," and follow the liquid carrying and battery protection regulations, carrying electronic cigarettes on board is not complicated. The key is to understand and comply with the regulations of the destination, avoiding using and charging them on the plane.
