Will tsa take my vape of my carry-on?

The TSA will not confiscate your electronic cigarettes in your carry-on luggage because they are allowed to be carried. However, the prerequisite is that you must comply with the strict regulations regarding the carrying method and packaging.

According to the regulations of the U.S. Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA), the following are the core rules for carrying electronic cigarettes on board:

Item Hand-carried luggage Checked luggage
Electronic cigarette devices (with batteries) Allowed ✅ Prohibited ❌
Backup lithium batteries Allowed ✅ (with electrode protection) Prohibited ❌
E-liquid (smoke oil) Allowed ✅ (comply with liquid regulations) Allowed ✅
Detailed carrying guidelines
To ensure a smooth security check, please note the following points:

Must be carried with you, not checked: All electronic cigarette devices (including disposable electronic cigarettes, rechargeable ones, and main units) and backup lithium batteries must be placed in your hand-carried luggage or on your person. This is to prevent fires caused by damaged or short-circuited lithium batteries in the cargo hold, as such fires are difficult to detect and extinguish in the cargo hold.

Prevent accidental activation of the device: You must take effective measures to prevent the heating elements of the device from being triggered accidentally during transportation. The safest method is to turn off the device power. If the device does not have a power switch, you can remove the cigarette cartridge or place it in an independent protective box.

E-liquid must comply with the "3-1-1" liquid regulations:

Each container of the carried e-liquid must not exceed 100 milliliters (3.4 ounces).

All liquid containers must be able to fit into a transparent, sealed plastic bag with a capacity of 1 quart (approximately 946 milliliters), and each person is allowed to carry only one.

Battery capacity limit: The rated energy of the lithium-ion batteries in the device must not exceed 100 watt-hours (Wh); the lithium content of lithium-metal batteries must not exceed 2 grams. The batteries of consumer-grade electronic cigarettes are usually far below this limit.

⚠️ Important reminder
Prohibited at all times: At any time and in any place on the plane (including the restroom), electronic cigarettes must not be used.

Prohibited charging on board: During the flight, it is not allowed to charge electronic cigarettes using the USB interface or power sockets on the plane.

Final decision: The security personnel have the final decision on whether the items can pass through the security check.

Ground regulations: After arriving at the destination, you must comply with the local laws regarding the use of electronic cigarettes. For example, in airports in California, New York, and other places, vaping is prohibited.

In simple terms, as long as you place the electronic cigarette devices in your hand-carried luggage and ensure that the e-liquid complies with the liquid carrying regulations, you can smoothly pass through the TSA security check.
