E-cigarette devices are battery-powered, and as long as you remember to keep the battery charged they're reusable (although maintenance and usability will depend on the type of e-cigarette device you're using). And, like a lot of other devices we use every day (such as smart phones and tablets) many e-cigs come with available USB and car charges. It's not only the rechargeable battery that makes these devices reusable; many are also refillable. The liquid in the cartridges needs to be resupplied regularly, either by inserting a new cartridge or refilling an empty one.
