1. A cartomizer, comprising:
- a housing including an outer tube and an inner tube within the outer tube, the outer tube and the inner tube defining a fluid reservoir configured to store an e-fluid;
a vaporizer including a heater surrounding a wick, the heater having at least one end portion connected to an electrical lead wire via a connection within the fluid reservoir, the wick configured to draw the e-fluid from the fluid reservoir to the heater, the heater configured to vaporize the e-fluid; and
at least one sleeve within the fluid reservoir and covering the connection, the at least one sleeve surrounding the connection such that a portion of the at least one sleeve is between the connection and the inner tube, the at least one sleeve disposed between the outer tube and the inner tube and without touching the wick, a diameter of the at least one sleeve being less than a diameter of the inner tube, the at least one sleeve configured to cover the connection so as to avoid or reduce a reaction between the connection and the e-fluid.
