According to Transportation Security Administration (TSA), electronic cigarettes can only be carried in carry-on baggage and the lithium-ion battery must not exceed 100 watt-hours (Wh). Passengers are required to prevent accidental activation of the heating device, therefore, TSA does not allow passengers use or charge e-cigarettes/ vapes on airplanes.
