The summer sun blazes with unrelenting intensity, turning each breath into a draught of searing air that clings to the lungs—an oppressive heat that borders on the unbearable. In such moments of sweltering discomfort, how sublime would it be to cradle a compact, exquisitely designed mini fan, its gentle currents sweeping away the stifling warmth to conjure the crisp, refreshing coolness of an autumn day?

Thankfully, our latest innovation—the CoolPrime D3 Portable Desk Fan—answers this very desire. In this blog, we’ll delve into the exceptional features that set the CoolPrime D3 apart, and explore how it is poised to elevate your summer experience into something truly refreshing.
一、Ultra-slim design for effortless storage

It boasts an ultra-slim profile—sleeker even than a book! Tuck it into a bookshelf, and it vanishes without a trace, taking up zero space. Whether slipped onto a desk or stashed in a backpack pocket, it tucks away effortlessly. For those in compact homes or always on the go, bulky fans will no longer be a source of hassle.
二、Exceptional battery life, keeping you cool all day long
That 10,000mAh high-capacity battery is truly a standout feature! When fully charged, it delivers up to 28 hours of continuous airflow, with flexible runtime ranging from 8 to 28 hours to suit your needs. Whether you’re constantly on the go outdoors or glued to your desk in the office, a single charge keeps it running from dawn till dusk—banishing "battery anxiety" for good. Be it summer outings or daily commutes, its steady breeze brings unwavering peace of mind.

It offers a full 180° rotation, letting you channel the breeze exactly as you wish—total control over your cool zone!
When working at your desk, adjust the angle to blow directly over the surface, keeping both your workspace and yourself cool and refreshed. Out camping, set it on a table and swivel it to face you, so that crisp airflow lands precisely where you need it. Come bedtime, angle it away from your head to avoid direct drafts, ensuring a comfortable, uninterrupted night’s sleep.
Better yet, it’s designed to hang too: hook it inside a tent, over a dorm bed rail—wherever you need that cooling touch, it “locks on” and delivers.
四、Emergency charging capability: a practical bonus that elevates its utility.

Surprise! It doubles as a power bank too. When your phone runs low on juice, this fan can step in to keep it going—charging an iPhone 12 up to 3 times, an iPhone 14 Pro 2.5 times, or an iPhone 16 Pro 2 times. Dependable when it matters most, it’s not just your “cooling companion” but also your “battery bodyguard.” Carry just this one device when you head out, and you can skip the hassle of bringing a separate power bank altogether!
