Technologies are generally described for air freshener devices. The devices may comprise an insertion section including electrodes. The electrodes may be effective to receive and conduct an electric current and to secure the devices to an electric source. The devices may include a base. The base may be attached the insertion section. The base may include a port effective to receive at least part of the electric current from the electrodes. The base may include a collar effective to apply heat sufficient to release a fragrance from a material infused with the fragrance when at least part of the electrical current is supplied to the collar from the electrodes. The device may include a cap. The cap may have a ring shaped cross-section and may be sized and shaped so as to be connectable to the base such that the port is accessible when the cap is connected.
