Various aspects of the present disclosure are directed to electronic cigarette temperature compensation.

An electronic cigarette system including a liquid capsule having a reservoir for holding vaporizable material, a holder-facing surface, a vapor pipe with an vapor inlet at the holder-facing surface, an inhalation opening, a liquid exit port arranged at the holder-facing surface, and a capsule holder for removably receiving the liquid capsule. The capsule holder including a capsule accommodating opening, a heating device, and a mesh for being soaked with the vaporizable material. When the liquid capsule and the capsule holder are interconnected to each other, a fluid chamber is formed between an outer surface the capsule accommodating opening and the holder-facing surface and when the liquid capsule and the capsule holder are interconnected to each other, a fluidic connection path is formed from the reservoir to the fluid chamber via the liquid exit port, to reach the inhalation opening.
