Various embodiments provide a pack for holding and re-charging an e-cigarette. The pack includes a pack battery; a body portion including a tube for receiving an e-cigarette; a re-charging mechanism for re-charging the e-cigarette received into the tube using the pack battery, wherein the e-cigarette can be re-charged in the tube without disassembly of the e-cigarette; and a dual activation mechanism comprising two separate triggers for causing the re-charging mechanism to begin re-charging the e-cigarette received into the tube using the pack battery. The re-charging begins only in response to the direct activation by a user of both of the separate triggers.
