Has a built‑in rechargeable battery (or accepts battery power) so it can run without being plugged into mains electricity
Specifications
- <p><strong>Blade / Fan Size</strong>: often <strong>16‑inch</strong> or <strong>18‑inch</strong> blade diameter. </p><p><br></p><p> • <strong>Power Source</strong>: hybrid — works on <strong>solar charging + internal battery + optionally AC mains</strong> (when available). </p><p> • <strong>Battery Type & Capacity</strong>: many use a <strong>lithium‑battery</strong> or sealed rechargeable battery; e.g. one model lists <strong>7.8 Ah, 7.4 V</strong> capacity (≈ 57.72 Wh) with solar charging. </p><p> • <strong>Power / Consumption</strong>: around <strong>25 W</strong> (fan working power) on some models. </p><p> • <strong>Runtime on Battery (Full Charge)</strong>: depending on speed/setting — some models can run from <strong>6 hours up to 12 hours or longer</strong> on a full battery charge. </p><p> • <strong>Fan Speed Settings</strong>: usually <strong>multiple speeds</strong> (e.g. low / medium / high) for adjustable airflow. </p><p> • <strong>Oscillation / Airflow Distribution</strong>: many have <strong>oscillation</strong> (fan head rotates) or some adjustable tilt/angle — to spread airflow across a larger area/room. </p><p> • <strong>Height / Stand / Portability</strong>: as a standing/pedestal fan — often with adjustable height or stable stand suitable for room placement. </p><p> • <strong>Additional Features (varies by model)</strong>: Some fans include extras — <strong>USB output</strong> (to charge phones or small devices), <strong>LED light / night‑light</strong>, <strong>remote control</strong>, and ability to work outdoors (with solar charging). </p><p><br></p><p><strong>✅ What These Specs Mean for Use — What to Expect</strong></p><p> • With a <strong>16–18” blade and 25 W power</strong>, the fan should deliver <strong>decent airflow</strong> for medium to large rooms.</p><p> • Thanks to the <strong>solar + battery + AC hybrid setup</strong>, the fan remains usable <strong>even during power outages or off‑grid</strong> — just place the solar panel under sunlight to recharge.</p><p> • <strong>6–12 hours runtime</strong> gives a good evening’s cooling without mains electricity. Great for blackout‑prone areas or outdoor use.</p><p> • Multiple speeds + oscillation allow you to <strong>adjust airflow intensity and coverage</strong>, making it versatile for different comfort needs.</p><p> • Extras like <strong>USB output</strong> and <strong>LED light</strong> add value — you might charge a phone or use as night‑light during blackouts.</p><p><br></p>
