Battery-powered E-cigarettes (e-cigs), vaporizers, vape pens, atomizers, electronic nicotine delivery systems

Electronic smoking devices when carried by passengers or crewmembers must be carried on one's person or in carry-on baggage. Electronic smoking devices are battery powered and have a heating element that vaporizes liquid. Passengers are required to take effective measures for preventing accidental activation of the heating element of the device when transporting the devices.

Examples of effective measures to deactivate the device include, but are not limited to: Removing the battery from the electronic smoking device; separating the battery from the heating coil; placing the electronic smoking device into a protective case; using a protective cover, safety latch, or locking device on the electronic smoking device's heating coil activation button; and electronics or technology in the device designed to prevent accidental activation, such as those requiring the electronic smoking device to be powered on before the heating coil button can be activated.

Spare lithium batteries also must be carried on one's person or in carry-on baggage and must be individually protected so as to prevent short circuits. Battery terminals (usually the ends) must be protected from short circuit (i.e., the terminals must not come in contact with other metal). Methods include: leaving the batteries in their retail packaging, covering battery terminals with tape, using a battery case, using a battery sleeve in a camera bag, or putting them snugly in a plastic bag or protective pouch.

Each battery must not exceed 100 Wh for lithium ion batteries or 2 grams for lithium metal batteries. Recharging of the devices and/or the batteries on board the aircraft is not permitted.

Check with your airline on any limitations on the number of devices that can be carried for personal use by a passenger.
