FAQ on Empty Disposable Vapes

Knowledge Base

Empty disposable vapes are best suited for medium to high-viscosity oils, including distillate, live resin, rosin blends, and most CO₂ oils. Thicker oils perform more reliably with ceramic, postless atomizer designs and help prevent leaks or flooding during use.

Yes. All of our empty disposable vapes pass heavy metal testing, with documentation available upon request. Most models use our postless ceramic B-Core technology, which delivers even heating, improved flavor, and better oil flow compared to traditional wick or post-based designs.

Leaks and burnt taste are usually caused by oil viscosity or voltage mismatch, not the device itself. Oils that are too thin can oversaturate the core, while voltages that are too high—especially with rosin or live resin—can burn the oil. For best results, use medium to high-viscosity oils and keep voltage between 2.0–2.2V when applicable.
