Smoore electronic cigarettes adopt a lithium-ion rechargeable battery to power the heating element. Battery life varies depending on the battery type and size, frequency of use, and operating environment. Many different battery charger types are available, such as wall outlet, car, and USB. The battery is generally the largest component of an electronic cigarette.

Smoore electronic cigarettes adopt an electronic airflow sensor to automatically（with inside auto switch） activate upon inhalation, while some models instead（with inside manual switch） have a manual button that the user must press while inhaling. Various other electronic circuits are usually adopted as well, such as a timed cutoff switch to prevent overheating, and an LED to signal activation of the device. An orange/blue-colored light is often chosen for its visual resemblance to actual burning tobacco in the front of the cigarette.

Smoore e-cig models are too small to house a standard-size cell and instead require a proprietary component made by ourselves. Then this unique battery and electronic components are housed within a single replaceable part, which is generally referred to in the industry simply as the "battery" — even though it actually contains many other components as well.
