The DVS holds 2 ml of high-quality e-liquid containing glycol, food-grade flavorings, and pharma-grade nicotine with two different nicotine levels: 1.8% (20 mg/ml) and 3.5% (39 mg/ml). Each device comes with a pre-charged ISO certified lithium-ion (Li-on) battery (280 mAh) that can provide up to 500 puffs (based on a puff duration of 1 second – may vary depending on individual usage patterns).
There are no buttons to push on the DVS. Instead, the device activates automatically upon puffing and deactivates automatically once the session is complete and no more puffs can be taken. Additionally, it features an integrated light system that offers real-time status updates regarding the device's operation. For example, two pulses indicate an error condition while the light pulses ten times when the battery is depleted.
