E-cigarettes with a power of 14 W

The devices with 14 W come from brands including DotMod, Geekvape and Aspire and are rarely tied to a single value. 16 W is listed alongside most often, together with a whole series of further values: 20, 22, 28 and 35 W. This staggering points to models that take several atomiser heads, each with its own power rating, or that work in steps.

Power and energy demand

• Energy over time: A device delivering 14 W converts half as much energy in the same time as one delivering 28 W.
• Battery life: With the same battery, one charge lasts correspondingly longer at lower power.
• Fixed quantity: The wattage describes the device, not the head; the head states its own recommended range.

Which of the listed values belongs to which head or step is stated in the model's product details.
