The lifespan of a disposable vape varies depending on factors like brand, e-liquid reservoir size, and usage frequency. Generally, it lasts around three days for moderate vapers (about 20 puffs daily), equating to approximately a month. Once depleted, it's disposed of responsibly and replaced. A disposable vape is a straightforward device, typically found in gas stations and convenience stores, sold pre-filled without technical details. Once the e-liquid is used up, the entire unit is discarded. Essentially, it's mostly cartridge with minimal battery, activated by inhaling to heat the liquid into vapor for easy, button-free vaping.
