| Compact, low-capacity | Small, lightweight; often pen-shaped or a short rounded bar | About 200–800 puffs | Simple, usually draw-activated, with few or no adjustable features | Generally has a smaller e-liquid reservoir and battery than larger formats. |
| Standard-size, fixed-use | Medium-sized stick or rectangular bar | About 800–2,500 puffs | Typically sealed and non-rechargeable, with an integrated battery and mouthpiece | The device is discarded when its battery or e-liquid is depleted, subject to local disposal rules. |
| High-capacity, larger format | Bulkier bar or box-like body, often with a larger reservoir | Claims commonly range from about 2,500 to 10,000+ puffs | May include a battery indicator, screen, or airflow controls | Puff figures are manufacturer estimates, not a standardized measure; actual use can differ substantially. |
| Rechargeable disposable | Usually medium to large; often a bar or compact box | Varies widely; often advertised from around 1,000 to several thousand puffs | Has a charging port, commonly USB-C; the e-liquid reservoir remains sealed | Recharging the battery does not refill the e-liquid. Follow product instructions and local battery-disposal guidance. |
| Pod-shaped disposable | Slim, compact body resembling a small pod device | Often about 300–1,500 puffs | Integrated pod and battery; commonly draw-activated with a minimalist exterior | Despite the pod-like shape, disposable versions are generally not designed for refilling. |
| Screen-equipped or adjustable disposable | Typically medium to large, with a wider body to accommodate controls or a display | Often advertised at several thousand puffs; figures vary by model | May display battery or e-liquid estimates and offer limited airflow or output settings | Displays and settings differ by device and may not provide precise measurements. |
