Lire une fiche technique de vape jetable

A spec sheet tells you what you are actually buying. For disposable vapes, four numbers decide whether a device sells well and whether it matches the price on the invoice: puff count, battery capacity in mAh, e-liquid volume in mL, and coil resistance in ohms. This guide shows how to read them, how they relate, and why the same “20000 puffs” label can describe two very different products.

What “puffs” actually measures

Puff counts are lab estimates based on a standardized draw, usually a draw of fixed duration and fixed air volume repeated until the device stops. They are a comparison point between products, not a promise of how many draws a specific customer will get. A customer who takes long, deep draws will see fewer puffs than the lab number; a customer who takes short draws will see more. So treat puff count as “relative size,” not as a guaranteed count.

This matters for buying because puff count is the headline number shoppers compare. If you understand that it is an estimate, you will stop being surprised when two devices with the same puff claim feel different in real use, and you will start checking the other three numbers before you reorder.

A useful habit is to write the puff number down, then immediately look for the mAh and mL next to it. If those two supporting numbers are missing from a listing, treat the puff claim with extra caution and ask the supplier for the full sheet before committing. A complete spec sheet is a sign the supplier knows its own product; a headline-only listing is a reason to wait.

Battery capacity, mAh, and why it matters

mAh, or milliampere-hour, is a measure of battery energy. A larger mAh generally means more total energy available to heat the coil and vaporize liquid. As a rough planning check, a device rated for more puffs needs proportionally more mAh, or a more efficient coil and a tighter draw. If two devices claim similar puff counts but one shows far less mAh, ask why before assuming they are equal.

You can do a quick sanity check: divide the battery mAh by the puff count to get an approximate energy per puff. Two devices with the same puff claim but very different energy-per-puff values are not built the same way. Neither is wrong on its own, but they will behave differently on the shelf and in the hand.

E-liquid volume, mL, and the puff-to-oil link

mL is the tank size, the amount of e-liquid the device holds. More puffs require more liquid, so a 20000-puff device typically carries noticeably more mL than a 12000-puff one. If a device claims a very high puff count but lists a tank that looks too small to support it, the puff number may be optimistic or the draws used in testing were unusually short.

For buying, the practical rule is to read mL alongside puffs. A believable high-puff device pairs a larger tank with a battery that can actually deliver the claimed draws. Our 12000 to 20000 puff category and the higher tiers let you compare how tank and battery scale as puff counts rise.

Coil resistance, ohms, and the draw feel

Resistance, measured in ohms, describes the coil. Lower resistance draws more power and tends to produce warmer, denser vapour. Higher resistance draws less power, runs cooler, and can stretch battery life. Resistance is less about “right or wrong” and more about the feel a customer prefers, but it explains why two devices with similar specs can vape differently.

Use resistance as a feel indicator, not a quality score. Match it to the customers you serve: cooler and smoother for casual buyers, warmer and denser for users who expect a stronger draw.

Why two “20000 puff” devices differ

Two devices can both say 20000 puffs and still be different products because the supporting specs vary. One may carry a bigger battery and a bigger tank, giving steadier performance deep into the life of the device. Another may hit the number with a smaller battery and a more restrictive draw, which feels different and may fade sooner. The label alone does not tell you which you are holding.

The table below is a planning reference for how battery and tank values generally scale across puff tiers. Treat the ranges as ballpark only. Always read the individual product’s listed specs, because exact figures vary by model and by brand.

Puff tier	Typical battery (mAh)	Typical e-liquid (mL)	Common buyer
12,000 to 20,000	roughly 600 to 1000	roughly 15 to 20	Casual and trial buyers
20,001 to 50,000	roughly 1000 to 1600	roughly 20 to 30	Regular daily users
50,001 and above	roughly 1600 and up	roughly 30 and up	Heavy, bulk-puff seekers

How to use spec sheets when choosing stock

Match the puff tier to the customer in front of you. The 20001 to 50000 puff category suits regular users who want a device that lasts, while the 50001 plus puff category serves heavy users who specifically ask for maximum puff counts. Casual buyers are often happy in the lower tier, which also keeps your per-unit spend lower.

When you compare two devices, cross-check mAh and mL against the puff claim, note the resistance for draw feel, and only then look at price. If you want help interpreting a specific listing, the customer help page explains how to reach us. Reading the sheet this way turns a confusing label into a buying decision you can defend.

A quick pre-buy check using all four numbers

Before any reorder, run a thirty-second check. First, does the puff count look supported by the mAh and mL listed? Second, does the resistance match the draw feel your customers ask for? Third, is the price fair once you account for the tier you reached by mixing flavours? If the first check fails, the device is probably not what the label implies. If the second fails, it may still sell but to a different customer than you expected. The third check is where mixed-flavour cartons earn their keep, because reaching a higher tier lowers the effective price without forcing a large single-flavour commitment.

This routine sounds small, but applied across dozens of SKUs it prevents the two expensive mistakes: buying a device whose specs do not add up, and buying the wrong feel for your local market. Both mistakes show up later as dead stock, which is exactly the cost this guide helps you avoid.

Frequently asked questions

Is the puff number a guarantee?

No. It is a lab estimate under standardized draws. Real usage varies with draw length and airflow, so treat it as a relative size indicator when comparing devices.

Which spec matters most for reorder decisions?

For most buyers, the combination of puff count and tank mL matters most, because it tells you how long a device lasts for your typical customer. Battery mAh supports that, and resistance explains draw feel.

Do higher puff counts always cost more per piece?

Usually the unit price rises with puff count because more battery and liquid are inside, but volume tiers can narrow the gap. Mixing flavours to reach a higher tier often lowers the effective per-piece cost even on bigger devices.

Where do I check a product’s exact specs?

Each product listing shows its own battery, tank, resistance, and puff figures. Read those numbers rather than relying on the tier name alone, and contact us through the help page if a listing looks unclear.
