Twenty thousand puffs is at the top end of what disposables reach, and the Sniper 20000 is built for people who'd rather not replace a device often. One of these lasts most vapers a good while, but the number on the box assumes light, short draws. Heavier use brings it down. Because no 900 mAh battery runs 20,000 puffs on its own, it recharges, so the e-liquid is what you're actually working through rather than the battery dying early. The screen shows you where both stand. Adjustable airflow lets you tighten it for a cigarette-style draw or open it for more vapour, and there are two modes if you want a stronger hit. Nicotine is 20 mg/mL salt. It's more device than a basic disposable, which is rather the point at this puff count.
