Pac Man Dual Chamber: How It Works, Pros/Cons, and Best Use Cases
Author: VapeBarLife Editorial | Updated:
How dual-chamber AIO housings work
Two tanks, one mouthpiece
Dual-chamber AIOs place two isolated reservoirs behind a shared mouthpiece. Each chamber has its own wicking/coil path, with airflow routed via a selector to prevent cross-contamination.
Switching: mechanical vs. electronic
Some units rely on a mechanical slider/rotary valve; others use an electronic switch that flips the active coil and updates the indicator. For a baseline single-chamber reference, see our category page Packman disposable.
Pros and cons
Advantages
- Flavor flexibility: two SKUs in one device for pilots, seasonal drops, or store demos.
- Stock efficiency: fewer shells on shelf for multi-flavor menus.
- User signaling: clear LED/display states reduce perceived “inconsistent hits.”
Trade-offs
- BOM & tolerances: more seals and moving parts raise tolerance requirements.
- Ingress risk: sliders/ports demand tighter dust/moisture control.
- QC complexity: two paths to test (pressure drop, output, leak/weep).
Best use cases
- Flavor pairings & collabs: limited runs combining complementary terp profiles.
- Retail sampling: single demo device covers two flavors—fewer demo units.
- Market testing: compare formulations quickly before committing to large POs.
Switching logic & indicators
State machines should debounce accidental toggles, cap puff duration, and expose simple fault codes (short/over-current/therm). Electronic switch units can display active chamber, puff count, and battery status—handy for training and support. Explore switch-centric housings here: pacman switch disposable.
Battery & transport safety (practical notes)
- Keep a UN 38.3 test summary for the exact cell/pack model on file for logistics partners.
- Ask suppliers about protections: over-charge/over-discharge, short-circuit, thermal cutoff.
- Store/ship within recommended temps; use original trays; avoid crush/impact loads.
Packaging responsibilities
As a hardware vendor we provide chassis, documentation, and dielines. Finished-goods labels, warnings, and any state-specific symbols are the licensee’s responsibility (requirements vary by jurisdiction).
Buyer checklist (EMPTY hardware only)
| Item | Ask for | Why it matters |
|---|---|---|
| Chambers & seals | O-ring durometers, cap compression, channel isolation | Leak/weep resistance under heat-soak & altitude |
| Switch design | Mechanical tolerance or electronic debounce spec | Reduced mis-switching and RMA |
| Coils | Ceramic grade & porosity vs. viscosity window | Flavor repeatability; clog mitigation |
| Battery docs | UN 38.3 test summary; charge profile | Freight acceptance & safety |
| Supply | MOQ, lead time, warranty, lot traceability | Launch continuity & after-sales clarity |
FAQ
Do you sell filled cannabis products?
No. We only supply empty hardware shells (no oil) for licensed B2B filling in legal jurisdictions.
How do dual chambers affect reliability?
More parts mean tighter tolerances and QC. Ask suppliers for pressure-drop, output, and leak data for both channels, plus switch endurance testing.
Are displays necessary?
Not required, but helpful for training and support; screen-less units can improve moisture resistance and BOM simplicity.
