There are lots of different SKE Crystal Bars, with some lasting as long as 600 puffs whilst others can last up to 5000 puffs. The number of puffs you'll receive depends on the e-liquid capacity, as well as the usage. Casual vapers will find that their vape lasts longer than those who are used to chain vaping.To make the most of your disposable devices we'd recommend regular vape breaks, however, if you find that your SKE vape runs out of battery life too quickly, you might be better off with a refillable pod starter kit instead. You can still enjoy the same Crystal Bar flavour too if you use their nicotine salt e-liquids.
