Quick answer:
Disposables (2 ml): typically 400–700 puffs, or 1–3 days for a moderate user.
Prefilled pods / Big Puff (2 ml + 10ml each): 5–15 days per pod; the device itself can last 6–18 months.
Refillable pod kits: coils last 5–14 days; pods 1–4 weeks; battery 6–18 months.
Sub-ohm tanks/mods: coils 3–10 days (sweet juice = shorter); batteries 200–500 charge cycles.
E-liquid: once opened, aim to use within 6–12 months (check “best before”).
Your mileage varies with puff length, wattage, nicotine strength, coil type, and how sweet or acidic your e-liquid is.

What affects lifespan
Wattage & heat: higher power burns e-liquid faster and wears coils sooner.
Coil type: tight MTL coils (≥1.0 Ω) sip; big mesh coils (≤0.3 Ω) gulp.
E-liquid recipe: high sweetener/dark flavours caramelise on coils.
Nicotine strength: too low → more puffs to feel satisfied.
Puff length: long 4–6 s drags drain batteries and overheat wicks.
Airflow: wide-open = more vapour per puff → more juice used.
Temperature & storage: cold lithium cells deliver less; hot cars age them faster.
Maintenance: priming coils, not over-tightening tanks, and cleaning contacts all help.


Signs your vape is finished
Disposables & closed pods
Very weak or burnt flavour
Flashing light / no draw
Dry hits even after resting
Refillable coils/pods
Flavour tastes muted, burnt, or sweet-burnt after a few puffs
Gurgling/leaks after many refills (pod seals tired)
Hotter vape at the same wattage
Batteries/devices
Charge that used to last a day now lasts half as long
Device randomly resets or struggles under load

How to make vapes last longer
For prefilled devices
Take shorter, gentler puffs (1–3 s)
Avoid chain vaping; let the wick re-saturate
Keep it warm (not hot); cold pockets reduce battery output


For pods & coils
Choose a nicotine strength that satisfies you with fewer puffs
Use 50/50 or 60/40 liquids for MTL pods (unless the device specifies otherwise)
Prime new coils and wait 5–10 min before first use; start at the low end of the wattage range
Avoid very sweet/dark juices if coil life matters most
Keep pods topped up; don’t let the wick run dry

For batteries/devices
Charge between roughly 20%–80% when practical
Use a reputable 5 V charger and the supplied cable
Don’t leave charging overnight on soft surfaces
Store around ~20 °C; avoid hot cars/windowsills

Simple puff & ml maths
Typical MTL puff uses about 0.003–0.005 ml of e-liquid.
2 ml at 0.004 ml/puff ≈ 500 puffs.
If you take 200 puffs/day, a 2 ml pod lasts ≈ 2.5 days.
Light MTL users often vape 1–3 ml/day; DTL users 5–15 ml/day.
Rule of thumb: If you’re emptying a 2 ml pod in under a day, raise nicotine strength (within legal limits) or tighten airflow/raise resistance.
