The electronic cigarette also has a small atomizer assembly with a mouthpiece, an atomizer, and a liquid reservoir. A small mechanical connector is designed to engage the second mechanical connector of the battery assembly. The assembly includes a connector shroud that has a shroud mechanical connector, and that tapers from a first outer periphery, which corresponds to the elongated housing size of the battery assembly, to a second outer periphery, which corresponds to the small atomizer assembly.
