Jelly USB Mini Fan: Portable 3-Speed Personal Cooler with 7.5-Hour Battery and Hanging Neck Strap

Meet the practical demands of personal cooling with this versatile jelly USB mini fan, designed for both handheld use and hands-free operation via its included hanging neck strap. Its core appeal lies in a combination of extended battery life, flexible usage, and highly portable design. Powered by an integrated 1100mAh rechargeable battery, it delivers up to seven and a half hours of continuous use, reducing the need for frequent recharges during long days outdoors, in the office, or while commuting. The fan features three distinct wind speed settings, allowing you to tailor the airflow from a gentle breeze to a more vigorous cooling effect. Measuring just 85mm tall, 54mm wide, and 31mm deep and weighing approximately 81 grams for the host unit, its compact jelly-like form factor ensures it fits easily into bags, pockets, or can be worn comfortably around the neck. Available in several fresh colour options like mint peach and sea salt berry, it combines functionality with a choice of styles.

Features and Construction

This mini fan is built around a set of specific, user-focused features that address core needs for portable, adjustable personal cooling. Its construction utilises multiple materials to balance durability, function, and user comfort in a lightweight package.

Material and Build

The fan's housing and key structural parts are made from ABS plastic, known for its good impact resistance and rigidity, helping protect the internal components. Polycarbonate (PC) is used where clarity or additional strength might be required, such as for fan blades or certain covers. Elements that contact the skin, like parts of the strap assembly, incorporate silicone for a softer, more flexible feel. Internal mechanical components, likely in the motor or hinge mechanisms, use metal for reliability. The adjustable strap itself is made from webbing fabric, providing a secure and breathable material for neck wear. This multi-material approach aims to create a product that is both sturdy enough for daily handling and comfortable for extended wear.

Size and Practical Fit

With dimensions of approximately 85mm in height, 54mm in width, and 31mm in depth, the fan maintains a very compact footprint. This size makes it highly portable, easily slipping into a handbag, laptop sleeve, or even a large pocket. The host unit's net weight of about 81 grams contributes significantly to its wearability, especially when used in the hanging neck mode, preventing neck strain during prolonged use. The webbing strap is adjustable to fit different neck sizes comfortably. The small size does not compromise on battery capacity, as it still houses a 1100mAh cell, demonstrating an efficient design that maximises runtime within a minimal physical space.

Uses and Placement

The dual-mode design significantly expands the scenarios where this fan can provide effective cooling, moving beyond simple handheld use to offer genuine hands-free convenience.

Event or Professional Use

At outdoor events, festivals, or sporting matches where outlets are scarce, the 7.5-hour battery life ensures cooling persists throughout the day. Professionals working in warm environments, such as kitchens, warehouses, or event setups, can use the hanging neck mode to keep cool while keeping their hands free for tasks. The quiet operation typical of small DC motors makes it suitable for use in shared office spaces or libraries without causing significant distraction. Its USB charging capability means it can be topped up using a portable power bank, laptop, or car charger, maintaining functionality far from traditional power sources.

Everyday Home Use

For everyday home use, it serves as a targeted personal cooler, allowing individuals to reduce reliance on energy-intensive air conditioning. It can be used handheld while reading, working at a desk, or doing household chores, or worn around the neck during activities like cooking, gardening, or DIY projects where hands-free operation is beneficial. The three-speed control lets household members of different ages find a comfortable setting, from a gentle airflow for a child to a stronger setting for an adult. The variety of colour options, including raspberry peach and sea salt mint, allows it to blend with personal style or home decor as a functional accessory.

Benefits and Buying Value

The value proposition of this mini fan centres on its combination of extended runtime, operational flexibility, and straightforward, low-maintenance design, all within a highly portable form factor.

Reuse and Low Maintenance

The fan is built for repeated daily use through its rechargeable battery system, eliminating the ongoing cost and waste of disposable batteries. The USB 5V/1A charging standard is universal, allowing you to use existing cables and adapters you likely already own. With no filters to clean or complex mechanical parts to service, maintenance is minimal; simply keep the fan blades clear of dust and charge the battery as needed. The sturdy ABS and PC construction is designed to withstand the bumps and minor drops associated with portable, personal electronics, supporting its reuse over many cooling seasons.

Why Choose This Product

Its key differentiators are the confirmed 7.5-hour runtime from a 1100mAh battery, the flexibility of three wind speeds, and the practical dual-mode design—all supported by its compact 85mm x 54mm x 31mm dimensions.
