A small fan/motor & blades to generate airflow. • A built‑in rechargeable battery so the fan can run without being plugged into mains power.
Specifications
Spec / Feature
Common / Example Value or Description
Fan Size / Blade / Type
Small — e.g. 6″ to 8″ blade (mini/desktop size) or small 12″ for slightly larger “table‑fan” style.
Power Source
Built‑in rechargeable battery + solar panel charging (sometimes also USB/AC charging)
Battery Type & Capacity
Example: ~ 2400 mAh battery (for an 8″ fan) — larger ones may use lead‑acid or 6 V/4.5 Ah batteries.
Solar Panel Input / Compatibility
Some models include a small solar panel (e.g. 6 V or with appropriate DC input) for charging battery.
Fan Power Consumption / Motor Wattage
Smaller fans tend to be lower power (e.g. ~ 5 W for mini clip/desk fans) ; small table/desktop solar fans might be higher depending on motor size.
Speed Settings / Airflow Control
Often have multiple speed settings (e.g. low / medium / high) to adjust airflow vs battery usage.
Operating / Runtime (on Battery)
For very small fans: maybe 3–7 hours (depending on speed/battery capacity). For slightly larger (8″ solar‑charged) fans: maybe 3–11 hours depending on speed.
Charging Time
If using solar panel: several hours under sunlight (depends on panel & sun exposure). If using USB/AC (for some mini fans), maybe 3–4 hours for full charge (varies by battery).
LED Light Feature
Many “solar‑fan + LED” models include built‑in LED lights — useful for nighttime or blackout situations.
Portability & Size / Weight
Compact and lightweight — easy to carry, move, or place on desk, bedside, balcony or for travel.
Extras (varies by model)
Some offer USB output (to charge phone/ small device), overcharge/over‑discharge protection, multiple power modes (solar / battery / mains), small stand or clip/mount for desks.
