1g vs 2g vs 3g Empty Disposables: Cost per ml, Yield & Failure Rates

Capacity choice is one of the simplest levers B2B buyers can pull—yet it hits nearly every KPI: cost per ml, perceived value, shipping efficiency, QA workload, and compliance risk.

1g: Flexible & Low-Risk

1g devices keep exposure per unit low and are forgiving for new fillers dialing in SOPs. They’re ideal for strain rotations, collabs, and regulated markets with tighter caps.

2g: Sweet Spot for Mature Operators

2g formats typically drive better cost per ml and reduce packaging waste. Once your line is stable, upgrading key SKUs to 2g can improve margins without sacrificing QC.

3g: Flagship Only

3g should be reserved for operators with rock-solid demand forecasts and robust QA. Larger volume magnifies any hardware or filling issue; only deploy with validated devices.

Compare performance and pricing directly via 1g disposable vape bulk, mid-range hero SKUs at 2 gram disposable vape bulk, and flagship options in 3g disposable vape bulk.

Key Takeaways for Cost & Rejection Rates

• Model cost per ml including expected DOA/defect rates, not just sticker price.
• Use pilot runs to establish your own failure benchmarks by capacity.
• Lock in suppliers that can repeat the same mold and cell batch over time.
