A personal vapor device having a disguised appearance is disclosed. The personal vapor device has an outer housing and removable lid that replicate the look of a conventional drinking container, such as a water bottle or drinking cup with a straw. An atomizing device, such as a cartomizer, is contained and concealed within the open interior of the outer housing. A mouthpiece extends through the removable lid and into the open interior. Atomized liquid from the cartomizer is delivered to the mouthpiece for delivery to the user. A power supply and a control circuit are contained within the open interior and, along with the atomizing device, are concealed within the outer housing. The disguised vapor device can be used without drawing attention to the user.
