Straight from the FAA "Electronic cigarettes, vaping devices. These devices are battery powered and have a heating element that vaporizes liquid (that may or may not contain nicotine). These devices are prohibited in checked baggage and may only be carried in the aircraft cabin (in carry-on baggage or on your person."
most tell you to take it out of your checked baggage. Just don't check it, you can carry it on the plane.
If you take it all apart yes I believe so
