The Elf Bar 600 comes pre-filled with 2ml of nicotine salt e-liquid, meaning that there is certainly enough nicotine to satisfy even the meanest of cravings. Equally as important, they come pre-installed with a 550mAh battery which is powerful enough to last the e-liquid’s entirety. Notice that everything has pre-completed for you? When using a disposable vape, vaping really couldn’t be easier.
