An Elf Bar BC5000, advertised with 5000 inhalations, will last up to a week for heavy vapers and an occasional vaper up to two weeks, maybe longer. Elf Bar vaporizers come in several sizes and have 27 different model types (and counting). The lifespan of an Elf Bar, such as the popular BC5000 model, varies depending on the user's vaping habits. For the average user who inhales around 132 puffs a day, an Elf Bar BC5000 can last up to 37.9 days, approximately 5.4 weeks.
This estimate is based on the 5,000 inhalations provided by the device. The time an elf lasts can last for days, months, weeks, or even years. The latter really depends on how you use it. How many puffs do you consume at once? The duration depends on the use and consumption of energy.
Even if you're not using it. You must keep it in a safe place. Keeping it protected from sunlight or strange places can even last for years in your Elf Bar.
