Quick answer: This is the central claimed-vs-measured evidence hub from VapeRisk Labs. It compares manufacturer or packaging claims with component markings, teardown observations, bench measurements and clearly labelled estimates from the specific retail units we examined. The current dataset covers eight devices. No advertised puff total on this page has been verified by a standardized puff-count test.
Use the linked model reports for the original photos, sample notes, method context and the exact limits of each finding. A claim, a visible marking, a bench measurement and an estimate answer different questions.
The clearest measured or observed gaps are: Vaporesso DOJO 0+10, 1,000 mAh nominal versus 826 mAh usable to a 3.27 V cutoff; Vozol Rave 40000, 20 mL labelled versus about 18.5 mL estimated effective oil-holding; Fumot T9000, 650 mAh on the examined device versus a 600 mAh internal cell marking; and IVG Air 2-in-1, 850 mAh on the device versus a 780 mAh internal cell marking. These are sample-level findings, not product-wide certification.

How to read this evidence
The evidence labels below are categories, not a ranking in which a marketing claim is automatically weaker or a bench number automatically proves every unit. Each label answers a different question.
| Evidence tier | Meaning | What it does not prove |
|---|---|---|
| Claim | A specification or statement from an official product page, manual, packaging or another named company source. | Independent verification by VapeRisk. |
| Marking | Text or a rating visible on the examined device, cell or component. | Usable capacity, performance or consistency across batches. |
| Observation | A photographed or documented feature found during teardown of the named sample. | That every unit or revision has the same construction. |
| Bench | A disclosed electrical, airflow, resistance, charging or capacity check on the examined sample. | Certification, accredited analysis or universal performance. |
| Estimate | A calculated or teardown-derived approximation whose method and rounding are stated. | A formal volumetric or chemical assay. |
| Not tested | The claim was recorded, but VapeRisk did not run the test needed to verify it. | That the claim is true or false. |

Comparison methodology
- Capture the source wording. Record the exact product, market and whether a number comes from an official page, packaging, the device or a component.
- Identify the sample. Tie every observation to the examined unit and avoid extending it to other batches or revisions.
- Separate the methods. Component markings, physical observations, electrical bench checks and estimates are not interchangeable.
- Compare like with like. Nominal battery capacity is not the same as usable capacity to a stated cutoff. Labelled liquid volume is not the same as estimated wick holding. A multi-refill kit total is not one tankful.
- Keep unresolved claims unresolved. Battery, liquid and coil data can test plausibility, but only a disclosed puff-count protocol can support a VapeRisk measured puff total.
Limitations
- Each product row is based on the specific unit documented in its linked teardown, generally one sample.
- Markets, batches, product revisions, modes, liquid fills, draw patterns, storage and charging conditions can change results.
- Component markings are reported as markings unless a separate capacity test was run.
- The Vozol liquid figure is an estimated effective oil-holding value, not an accredited volumetric assay.
- No puff total in this dataset was verified through a standardized machine-puff count.
- These teardowns do not certify safety, compliance, toxicology, emissions or health outcomes.
High-puff claim context
A battery can support or constrain a high-puff architecture, but it cannot prove the advertised total. Liquid volume, coil condition, output mode, rechargeability, draw duration, interval, airflow and the stopping rule all matter. Start with the consumer-facing puff-count comparison guide, then use Battery Capacity vs Puff Count for the method. Charging, damage, travel and disposal are separate safety questions covered by the Vape Battery Safety checklist.
Related product examples include the Geek Bar Pulse X 25K review, Foger Switch Pro 30K review and 0+10 and 2+10 format guide. Their headline numbers remain claims unless the individual page states that a controlled puff-count test was run.
Sources and provenance
VapeRisk primary evidence: the eight linked teardown reports above, including their sample notes, component photographs and disclosed bench checks. The comparison page does not replace the product-level report; cite the teardown when a finding depends on its detailed method.
Official product references used to document claim wording or architecture:
- Vozol official product catalog (RAVE 40000 product listing and feature claims).
- Fumot official T9000 page (2+10 format and 600 mAh official specification).
- Higo official BB4000 page (2+4 mL, 900 mAh and 4,000-puff claim).
- JNR 100K official product page (64 mL / 100K kit claim and architecture).
- IVG regional official Air product page (two-pod 2-in-1 architecture).
- Elf Bar Germany official MAX page (650 mAh rechargeable device specification).
Where an exact official public product page could not be confirmed during this audit, the table labels the source as packaging, device marking or the linked teardown instead of inventing an official citation.

FAQ
What does claimed vs measured mean on VapeRisk?
A claim comes from a named manufacturer, official page, manual, packaging or device marking. A measured result comes from a disclosed check on the specific unit VapeRisk examined. The page keeps those sources separate.
Did VapeRisk verify any advertised puff count in this table?
No. None of the advertised puff totals in this dataset was tested with a standardized puff-count protocol. Hardware findings can inform plausibility, but they do not convert a label into a measured puff total.
Does 826 mAh versus 1,000 mAh mean the DOJO label is false?
No. The 1,000 mAh figure is a nominal cell rating, while 826 mAh is the usable capacity measured on one unit to a stated 3.27 V cutoff. The comparison is useful for runtime expectations but is not a finding of false labeling.
Why separate official claims from device and cell markings?
They can differ. The Fumot T9000 official page specifies 600 mAh, the examined device was marked 650 mAh, and its internal cell was marked 600 mAh. Recording each source prevents one label from being mistaken for another.
Are estimated liquid capacities the same as laboratory volume tests?
No. The Vozol figure is an estimated effective oil-holding value from the teardown. It is clearly labelled as an estimate and should not be presented as an accredited volumetric assay.
How often is this evidence hub updated?
It is updated when VapeRisk publishes a qualifying teardown, documents a correction or obtains better source evidence. Material changes are listed in the version table rather than silently changing the comparison.
