Portable lithium 8 inch fan

    ₦25,000.00

    Key Features
    • Power Source: Runs on a removable or built-in high-capacity lithium battery (commonly rated from 21V up to 48V or 6,000mAh) that charges via a wall adapter. 
    • Airflow & Motor: Equipped with a high-performance copper or brushless motor driving an 8-inch blade span, usually featuring 2 to 3 adjustable speed settings. 
    • Build Quality: Features a sturdy metal wire frame or durable ABS plastic body with a rotating or tilting head for directional cooling. 
    • Runtime: Offers between 3 to 8 hours of continuous cordless operation depending on the speed setting and battery capacity. 
    • Portability: Lightweight design with a stable base or handle, ideal for desktops, workshops, camping, and emergency blackouts
    Category:
      A portable lithium 8-inch fan is a high-efficiency, cordless cooling solution engineered to deliver reliable airflow in environments without immediate access to electrical outlets. Combining a compact 8-inch blade diameter with the advanced energy density of rechargeable lithium-ion battery technology, these units bridge the gap between weak personal USB fans and bulky, corded industrial air movers. They are widely utilized for emergency preparedness during power outages, site work in construction and automotive workshops, and recreational outdoor activities like camping.

      ⚙️ Core Technical Specifications

      • Battery Architecture: Powered by a rechargeable lithium-ion system, these fans often utilize multi-cell packs (ranging from 18V to 21V configurations or internal 6,000mAh to 10,000mAh cells). This chemistry ensures a flat discharge curve, meaning the fan maintains consistent airspeed until the battery is entirely depleted rather than slowing down gradually.
      • Motor Technology: Most premium models utilize brushless DC (BLDC) motors or heavy-duty copper-wound motors. BLDC motors minimize mechanical friction, which significantly reduces operating noise, limits heat generation, and extends the overall lifespan of the fan.
      • Speed & Control: Features a multi-stage control switch (typically 2 to 3 discrete speed settings, or a stepless variable dial) allowing users to balance the immediate need for high velocity against maximum battery longevity.
      • Physical Dimensions & Build: The 8-inch blade assembly is housed within a protective high-impact ABS plastic or heavy-duty steel wire shroud. The entire chassis is designed with a small footprint, usually weighing between 1.2 to 2.0 kg (with battery attached), making it highly transportable.

      🔋 Operational Performance & Runtime

      The operational endurance of the fan is directly tied to the selected speed profile and the total watt-hour (Wh) capacity of the attached lithium battery.
      • Low Speed: Prioritizes energy conservation. It provides a gentle, quiet breeze ideal for overnight use in tents or quiet office spaces, yielding an extended runtime of 6 to 12+ hours.
      • Medium Speed: Offers a balanced performance tier suitable for standard daytime cooling, averaging a runtime of 4 to 6 hours.
      • High Speed: Maximizes cubic feet per minute (CFM) of airflow to rapidly cool a workspace or counter stagnant, humid air. Due to increased power draw, the runtime at peak performance generally ranges from 2 to 3.5 hours.
      • Recharge Cycle: Utilizes standard DC wall adapters. A full depletion-to-charge cycle typically takes between 3 to 5 hours. Many modern iterations feature battery management systems (BMS) with LED indicators to display remaining power increments (e.g., 25%, 50%, 75%, 100%).

      🛠️ Key Design & Functional Highlights

      • 360-Degree Adjustability: The fan head is mounted on a dual-axis or vertical pivoting hinge, allowing a tilting range of up to 180° or 360°. This enables precise directional cooling or indirect air circulation by bouncing airflow off walls or ceilings.
      • Hybrid Power Options: Many variants feature dual-power functionality. When an electrical outlet is available, they can run indefinitely using an AC wall adapter while simultaneously charging or preserving the battery pack for later cordless deployment.
      • Ergonomic Portability: Built with an integrated top-carry handle and a wide, stable base plate to prevent tipping on uneven surfaces like grass, dirt, or work benches. Some models incorporate hang hooks, magnets, or screw-mounting slots on the base for overhead placement.
      • Auxiliary Power Bank Function: Leveraging the onboard lithium battery, some models include a standard 5V USB output port, converting the fan into an emergency power bank capable of charging smartphones, headlamps, or other small electronic devices.

      🗺️ Target Applications

      • Emergency & Home Backup: Acts as a vital cooling appliance during sudden blackouts or rolling grid failures, preventing heat exhaustion in poorly ventilated living spaces.
      • Workshops & Construction Sites: Provides targeted cooling for mechanics, carpenters, and contractors working in unconditioned environments, garages, or tight crawlspaces where trailing extension cords pose a tripping hazard.
      • Outdoor Recreation: Compact and lightweight enough to fit into vehicle trunks or camping gear setups, supplying essential airflow inside tents, cabins, or recreational vehicles (RVs).
