Osmo Neck Fan

4000 mAh Rechargeable Battery for Up to 12 Hours of Extended Cooling

Fumbling with weak, low-capacity wearable fans that die after just an hour or two can leave you completely stranded in the heat during a busy day. This premium JISULIFE Portable Neck Fan eliminates battery anxiety by incorporating a heavy-duty 4000 mAh rechargeable battery core. Engineered for long-lasting, off-grid performance, this high-capacity power system delivers up to 12 hours of continuous cooling on a single charge. Whether you are commuting to work, walking your dog, spending a full day at an outdoor theme park, or managing a long shift, this dependable battery ensures you stay comfortably chilled without the constant need to track down a charging outlet.

Five Speed Selections Coupled with Three Versatile Wind Matrices

A generic, single-speed fan rarely provides the exact level of airflow you need, often proving too loud for a quiet office or too weak for an intense outdoor hike. To give you ultimate climate control, the JISULIFE system offers an advanced 5-speed manual selector paired with 3 distinct specialized wind types:

• Natural Wind Mode: Mimics an organic, outdoor breeze, making it ideal for standard daily use and relaxation.

• Sleep Wind Mode: Delivers an ultra-gentle, whispered airflow path carefully tuned to keep you comfortable at night without causing chills.

• Prevailing Wind Mode: Fires a concentrated, high-velocity stream designed to rapidly combat heavy sweat and intense heat spikes.

Ultra-Lightweight 150g Chassis Built for Uninhibited On-the-Go Travel

Heavy, rigid neck accessories can rapidly cause cervical muscle fatigue, neck stiffness, and painful skin chafing during long hours of active movement. Designed with a strict focus on ergonomics, this portable neck fan weighs an incredibly light 150g, making it feel virtually weightless around your shoulders. Its sleek, compact layout is explicitly optimized for effortless portability, slipping smoothly into your travel luggage, gym bag, or daily backpack. It serves as the absolute perfect companion for active global travelers, theme park visitors, festival-goers, and outdoor fitness enthusiasts who refuse to let hot weather slow them down.
