<P> The larger battery sections used also allow larger tanks to be attached that can hold more e-liquid . Recent devices can go up to 8 V, which can heat the e-liquid significantly more than earlier generations . </P> <P> A fourth - generation e-cigarette became available in the U.S. in 2014 . Fourth - generation e-cigarettes can be made from stainless steel and pyrex glass, and contain very little plastics . Included in the fourth - generation are Sub ohm tanks and temperature control devices . </P> <P> An atomizer comprises a small heating element that vaporizes e-liquid and a wicking material that draws liquid onto the coil . Along with a battery and e-liquid the atomizer is the main component of every personal vaporizer . A small length of resistance wire is coiled around the wicking material and connected to the integrated circuit, or in the case of mechanical devices, the atomizer is connected directly to the battery through either a 510, 808, or ego threaded connector . 510 being the most common . When activated, the resistance wire coil heats up and vaporizes the liquid, which is then inhaled by the user . </P> <P> The electrical resistance of the coil, the voltage output of the device, the airflow of the atomizer and the efficiency of the wick all affect the vapor coming from the atomizer . They also affect the vapor quantity or volume yielded . </P>
