Short answer
A 1-gram disposable vape cart holds about 150 to 300 puffs. A 0.5-gram cart holds about 75 to 150. Oil volume sets the ceiling. The battery sets the floor.
A person who takes 10 puffs a day finishes a 1-gram cart in 15 to 30 days. A person who takes 50 puffs a day finishes the same cart in 3 to 6 days. Both numbers assume the battery holds a charge for the full tank. Many disposables do not.
Puff counts by cart size
- 0.3 g: 45 to 90 puffs. Common in sample packs and travel sizes.
- 0.5 g: 75 to 150 puffs.
- 1 g: 150 to 300 puffs. The standard size in US dispensaries.
- 2 g: 300 to 600 puffs. Fewer devices carry this size.
Draw length drives these ranges. A 3-second draw moves about 3 to 6 mg of oil. A 6-second draw moves about 6 to 12 mg. Longer draws cut the puff count.

What changes the count
Voltage
Low voltage at 2.4 V to 2.8 V vaporizes oil at a slow rate. High voltage at 3.8 V to 4.2 V makes larger clouds and burns oil faster. Most disposables ship at a fixed voltage. A few offer two or three heat settings.

Draw length and draw count
Two users with the same cart can differ by 100 puffs or more. Draw length matters more than draw count.
Oil viscosity and fill weight
Thick live resin and rosin move through a wick at a slow rate. Thin distillate with added terpenes moves faster. A cart labeled 1 g may hold less oil after production loss. Some states allow a small variance between the label weight and the fill weight.
Clogs and leaks
Oil that clogs the mouthpiece or leaks into the airway is oil you cannot vape. Clogs and leaks remove oil from the usable total. No published standard measures the size of that loss.
Battery
Most disposable carts use a 280 mAh to 400 mAh battery. A 350 mAh cell at high voltage can die after 100 to 150 puffs. That leaves oil in the tank. Rechargeable disposables with a USB-C port avoid this. Units without a charge port do not.
How long a cart lasts on the shelf
Unopened carts hold quality for 12 to 24 months when stored away from heat and light. After the first pull, most producers suggest use within 6 to 12 months. Terpenes oxidize. Oil darkens. Flavor drops before potency does.
Store carts upright at 60 F to 70 F. Heat above 80 F thins oil and pushes it into the airway. Cold thickens oil and can slow the wick. A dark drawer at room temperature works.
Signs a cart is finished
- No vapor on a full charge.
- Burnt taste at a low heat setting.
- Oil level at or below the intake holes.
- A draw that produces nothing after a 10-minute rest.
What is not known
No industry standard defines a puff. Device makers do not publish test methods for puff counts. Numbers on packaging cover oil weight, not session length. Treat any single puff figure as an estimate.
