A dual vaporizer battery device is provided. The device includes a first battery housing having a first end opposite a second end and a second battery housing having a proximal end opposite a distal end. A first battery is disposed within the first battery housing and a second battery is disposed within the second battery housing. The first end is pivotally affixed to the proximal end via a hinge. The first battery housing is selectively movable relative to the second battery housing between a linear configuration and a parallel configuration. The first battery housing is coaxial relative to the second battery housing when in the linear configuration. A connector is disposed on each of the second end and the distal end, wherein each connector removably secures a vaporizer housing thereto, such that each vaporizer housing is in operable communication with each of the first and second batteries.
