How Dual Cart Batteries Work

Three core functions across every device in this collection:

1. Single-cart mode: selector set to one side, draws from one 510 cartridge only. Battery drain identical to a standard single-cart 510 battery. Use this for everyday sessions when you only want one strain.
2. Strain switching: flip the selector mid-session. Instant cart switching with no unscrewing, no fumbling. Load a daytime sativa and a nighttime indica and alternate throughout the day.
3. Dual-fire mode: selector centered, both carts fire simultaneously. Blended hit combining the terpene profiles and cannabinoid ratios of both oils. More vapor density, more intensity. Start at lower voltage when dual-firing to gauge the combined draw before increasing.
