JISULIFE Life4 Neck Fan

Some cooling you point at yourself; some cooling you wear. The JISULIFE Life4 Neck Fan belongs firmly to the second kind — a bladeless neckband that rests on your shoulders and wraps your face and neck in a 360° breeze while your hands stay completely free. The jisulife life4 pushes air through 80 precision vents with dual centrifugal turbofans spinning up to 8,000 RPM, across 5 speed levels, at a whisper-quiet under 25 dB. Whether you are commuting, cooking, walking, or working through a hot afternoon, it delivers steady personal cooling that travels with you.

Design and Build

The Life4’s U-shaped neckband is bladeless by design — there are no exposed blades to catch hair, clothing, or curious fingers. Air is generated by hidden turbofans and expelled through the 80 vents arranged around the inner curve of the band, so the breeze reaches you from every direction at once. The matte black finish keeps the look understated, and the soft TPE silicone contact surface is designed for comfortable all-day wear.

Comfort engineering shows in the details: breathable mesh channels, an adjustable curvature from 15° to 30° so the band fits different neck shapes, and a non-slip grip texture that keeps it in place while you move. The UV-resistant ABS casing with shock-absorbing reinforced corners handles daily wear and outdoor use, and the whole unit weighs just 254 g — light enough to forget you are wearing it.

Airflow and Performance

Airflow comes from dual centrifugal turbofans — compact, high-speed blowers — guided through ducting optimized for even distribution. The 80 vents ring the band so your face, neck, and the sides of your head all get cooled. Directional airflow can be tilted 30 degrees to aim the stream exactly where you want it.

Five speed levels span an airflow intensity of 3 to 8 metres per second, with the turbofans spinning up to 8,000 RPM at the top end. The jisulife life4 lets you step from a barely-there breeze for the office to full Turbo for a midday walk in the sun. Five steps of adjustment mean you can match the cooling to the moment instead of settling for too-little or too-much.

Battery and Charging

Runtime is a genuine strength: up to 16 hours on speed 1, up to 8 hours on speed 3, and 2.5 hours in Turbo mode, per the page’s figures. One honesty note: the product page lists the battery capacity as 5000mAh in one place and 4000mAh in another, so this listing states both figures and does not pick one for you — confirm the exact capacity with the store if it matters to you.

Charging is USB-C with PD fast-charging support at 18W, and a full recharge takes about 2–3 hours. That speed matters for a wearable: plug it in during lunch or between shifts and it is ready for the next stretch. The included USB-C cable gets you started, and any standard USB-C charger you already own works too.

Controls and Features

Controls sit right on the band — buttons you can reach without removing the fan — and the headline feature is quietness: under 25 dB, quieter than a whispered conversation. The jisulife life4 uses sound-dampening foam chambers and precision-balanced blades to keep the noise down, so it suits noise-sensitive environments like offices, libraries, and public transport without drawing stares.

Smart features protect both you and the battery: the intelligent power management system auto-shuts the fan down if your head tilts beyond 30 degrees while wearing it, and a low-power standby mode with battery health monitoring keeps the cell in good shape between uses. Add IPX4 weather resistance for light sweat and splashes, and the Life4 is built for the messy reality of outdoor life.

Frequently Asked Questions

Is the JISULIFE Life4 an original JISULIFE product?

This listing is for the JISULIFE Life4 as catalogued by Gadget Superb under the JISULIFE brand. The store does not claim official-distributor status for any brand it carries. If authenticity documentation matters to you, message the store on Messenger or email care@gadgetsuperb.com before ordering and they will clarify what they can share.

This product carries a 7-day store warranty as listed in its specifications above. If warranty terms matter to your purchase, please confirm the details with the store — via hotline 09638054751, care@gadgetsuperb.com, or Messenger — before you place your order.

How long does delivery take, and what are the charges?

Inside Dhaka, delivery costs ৳70 and takes 1–3 working days; outside Dhaka, it costs ৳120 and takes 2–5 working days. These are estimates, not guarantees, since courier conditions vary. Your jisulife life4 ships once you place a cash-on-delivery order.

How does cash on delivery work? Can I check the fan before paying?

Cash on delivery means you pay the courier in cash when the parcel arrives. Gadget Superb never asks for advance payment, card details, OTPs, or mobile-banking PINs. Couriers generally do not allow opening a parcel before payment, so check your JISULIFE Life4 right after the courier leaves and contact the store within the 7-day return window if anything is wrong.

What is the return policy if my JISULIFE Life4 arrives faulty?

Every Gadget Superb product carries 7-day easy returns. If your jisulife life4 arrives damaged or faulty, keep it in its original condition with the box and accessories, then start a return with your order number via hotline 09638054751, email care@gadgetsuperb.com, or Messenger.

How long does the battery last in real use?

Up to 16 hours on speed 1, up to 8 hours on speed 3, and 2.5 hours in Turbo, per the page’s figures. Because the page lists two different battery capacities (5000mAh and 4000mAh), treat these runtimes as the page’s own estimates and message the store if the exact capacity matters to you.

How do I charge the JISULIFE Life4, and how long does it take?

The fan charges over USB-C with PD fast-charging support at 18W, and a full recharge takes about 2–3 hours. A USB-C cable is included in the box, and any standard USB-C charger you already own works too.

Is the JISULIFE Life4 quiet enough for an office or library?

Yes — it runs at under 25 dB, quieter than a whispered conversation, thanks to sound-dampening foam chambers and precision-balanced blades. The jisulife life4 is designed for exactly these noise-sensitive environments: offices, libraries, and public transport.

What exactly comes in the box?

The product page confirms three items: the JISULIFE Life4 neck fan, a USB-C charging cable, and a user manual. If your parcel is missing any of these, contact Gadget Superb with your order number and the team will resolve it.

Can I get the JISULIFE Life4 gift-wrapped?

Gadget Superb does not advertise a gift-wrapping service, so gift wrapping is not promised with this order. Buying the JISULIFE Life4 as a gift? Message the store on Messenger before ordering to ask what packing they can arrange.

What is the price of the JISULIFE Life4 in Bangladesh?

The current price appears on the product page and can change during sales, so no figure is quoted here. Check the live jisulife life4 page on Gadget Superb for today’s price — that is the amount you pay in cash on delivery, plus the standard delivery fee.

How do I clean and care for the fan?

Wipe the neckband and air vents of your JISULIFE Life4 with a soft, dry cloth, and keep the vents free of dust. It is IPX4 splash-proof, so light sweat is fine — but do not submerge it, and let it dry before charging. Store it in a dry place, avoid drops, and recharge with a standard USB-C charger — unplugging once full keeps the battery healthy.
