Tombstone Battery - Hamilton Devices

The one that started the dual-cart revolution—Hamilton Devices' original Tombstone proved in 2020 that consumers genuinely wanted to fire two 510 cartridges simultaneously, spawning an entire sub-category of dual-cart batteries. The original's fixed voltage and inhale-only activation kept things dead simple for early adopters, and the concealed design shocked reviewers who couldn't believe both carts disappeared entirely inside the body. While the V2 has since addressed the original's voltage limitation, the first-generation Tombstone maintains a loyal user base among customers who prefer the simplicity of "just inhale"—no button, no voltage choices, no decisions. The dual-fire capability opened up the hybrid mixing use case that has since become a cultural phenomenon: sativa + indica, THC + CBD, or two completely different flavor profiles blending on every draw. For retailers who stock the V2, the original Tombstone serves as a budget alternative that captures price-sensitive dual-cart-curious customers who might otherwise walk away.
