Abstract: The present application is directed to electronic cigarette accessories. A battery for electronic cigarette includes a housing, a battery and four ports, wherein two ports are voltage output ports, the remaining two ports are expansion ports or voltage output ports. The present application can allow the battery for electronic cigarette to possess expansion capability through providing two voltage outport ports and two expansion ports, so as to facilitate the exchange of the internal information of the battery for electronic cigarette with the external information or an increase in the output power of the battery, allowing the battery to be able to supply energy at load with greater power. Furthermore, the output interface of the battery for electronic cigarette does not require sophisticated metal components, which production cost is half of that for metal connectors.
