In detail: Bearwind Turbo Fan 4000mAh
The Bearwind Turbo 4000mAh is a handheld fan that leans on raw power thanks to its 4th-generation airflow system: a 7-blade turbo design paired with a brushless motor capable of pushing airflow up to 9 m/s, about three times stronger than an ordinary fan according to the manufacturer. That power is finely adjustable across 5 speed settings, from a discreet breeze to the strongest possible airflow, for personalised comfort at the desk, while travelling or outdoors.
Its 4000 mAh battery claims up to 12 hours of runtime: low settings last through an entire night, while the highest speed is enough to last through a whole concert or an evening outdoors. Charging is via USB-C, fast, with a full charge in around 3 hours, a convenient standard that lets you share the same cable as a recent smartphone.
Its 180° foldable design, fitted with an adjustable lanyard, makes it a genuinely 3-in-1 device: usable held in the hand, standing on a desk thanks to its stable base, or worn around the neck for hands-free use on a walk, at a festival or on public transport. A built-in LED screen constantly displays the battery charge level, a handy way to plan the next recharge.
With compact folded dimensions of 4.6 x 5.8 x 17 cm and a featherlight weight of about 0.19 kg, it slips effortlessly into a pocket, handbag or backpack. The Bearwind Turbo 4000mAh is available in several colourways (bright purple and champagne gold, black and silver, pink and rose gold, or blue), making it as much a practical accessory as a thoughtful summer gift.
In practice, this kind of compact turbo fan mainly appeals for its versatility and its high airflow for such a small footprint, the logical trade-off being, as with most powerful fans in this category, noise that becomes more noticeable on the higher speeds. A solid pick for anyone after genuine, portable airflow, at the desk or on the move.

In short, the Bearwind Turbo 4000mAh stands out with the highest airflow of the three (9 m/s), thanks to its 4th-gen airflow system, while keeping a compact 3-in-1 format with LED display. The Diveblues answers with unmatched adjustment granularity (100 steps) at a lower price, while the HandFan focuses on a far longer battery life and a backup power bank function. For anyone prioritising raw airflow power in a compact, versatile format, the Bearwind remains the most convincing choice of the three.

Our tester's verdict: Benoit Richard
I tested it over several properly hot days, standing on my desk and then worn around the neck on a walk into town. On speeds 4 and 5, the airflow genuinely surprises for such a compact unit: the brushless motor pushes a clean, noticeably stronger stream of air than most handheld fans I have handled before. The 180° folding hinge changes daily use in a real way: laid flat, it becomes a proper desk fan without me having to hold it, and worn around the neck with the adjustable lanyard, it frees up both hands on a walk. The LED screen showing battery level is a nice touch, always useful to know where you stand before the next charge. Battery life holds up on low speed, easily covering a whole evening, but it drops noticeably once you push the higher settings. The one real downside after several outings: noise becomes fairly noticeable on the top two speeds. For such a compact 3-in-1 fan, the Bearwind Turbo 4000mAh remains a convincing pick whenever you want genuine airflow rather than a decorative breeze.
