How to choose a dual cart battery
1) Discreet carry versus maximum battery capacity
Dual cartridge devices are often larger than single-cartridge batteries. If discreet carry is the priority, choose models specifically designed to be compact. If you want longer runtime, prioritize models built around higher capacity.
2) Activation style: button activated versus auto-draw
-
Auto-draw models activate when you inhale, which many customers prefer for simplicity. Prefer no buttons? Shop Auto-draw cart batteries that activate when you inhale.
-
Button activated models give more control and are common when a device offers more settings.
3) Voltage control (if you want more control)
Some dual cart batteries offer adjustable voltage. Adjustable voltage is useful if you want more control over heat and you rotate between cartridges that may perform better at different heat levels. If you want “grab and go” simplicity, a basic model can still work well.
4) Cartridge fit considerations
Most standard 510 thread cartridges work well, but extra-wide cartridges can create fit issues on some dual devices. If you frequently use wider cartridges, prioritize models with more clearance around the cartridge openings. Not sure what ‘510 thread’ means? Start with our 510 thread batteries collection for universal cartridge compatibility.
