Super Strong, Ultra‑Quiet Turbo Airflow

Unlike ordinary flat‑blade mini fans, the iTurbo uses a turbo fan structure to concentrate airflow and increase wind speed. According to retailer and brand information:

Wind speed can reach up to 9.2 m/s at the highest setting.
The five speed modes range roughly from 5.2 m/s (breeze) to 9.2 m/s (strong): Breeze (5.2), Natural (6.2), Comfortable (7.0), Fresh (8.1), Strong (9.2).
It is described as around 3× stronger than ordinary handheld fans, giving much faster and more noticeable cooling on hot days.

At the same time, product descriptions emphasize an ultra‑quiet design, so you can enjoy strong airflow without loud fan noise, even at higher levels.

Foldable 3‑in‑1 Design: Handheld, Neck‑Hanging and Tabletop

The Diveblues iTurbo Fan is designed to adapt to different situations with a 3‑in‑1 usage concept.

You can use it in three main ways:

Handheld mode – simply hold the fan for direct cooling while walking, queuing or commuting.
Neck‑hanging mode – attach the included lanyard and wear it around your neck, leaving both hands free while airflow is directed towards your face and upper body.
Tabletop mode – fold the fan body and place it on a desk or bedside table as a small stand fan.

The fan can be folded at an adjustable angle up to about 90°, allowing you to tilt and aim the airflow exactly where you need it. This flexibility makes it more practical than single‑angle fans for home, office and travel use.

LED Digital Display for Speed and Battery

A standout detail of the iTurbo fan is its LED digital display, something not commonly found on basic portable fans.

The display lets you:

See the current wind speed level (1–5) clearly.
Monitor remaining battery power so you know when to recharge, reducing the risk of the fan suddenly turning off when you’re outside.

This small feature adds a lot of convenience, especially for users who commute or stay outdoors for longer periods.

4000mAh Battery, USB‑C Charging and Long Runtime

The Diveblues Foldable Handheld iTurbo Fan is equipped with a 4000mAh lithium battery, offering long runtime in a lightweight body.

Battery and charging details:

Battery capacity: 4000mAh (larger variant of the iTurbo series).
Runtime: around 4–12 hours, depending on wind speed level; some listings mention up to around 11–11.5 hours at lower speeds.
Charging time: about 4 hours via USB‑C (USB‑A to USB‑C cable usually supplied).

This is more than enough for a full working day or a long outing if you use mixed speed levels and charge it overnight.

Compact, Lightweight and Easy to Carry

Despite its strong airflow and 4000mAh battery, the iTurbo fan remains compact and lightweight.

Key physical specs (typical values):

Dimensions: around 15.2 cm × 4.8–5 cm × 4.3–5 cm.
Weight: approximately 136–150g, light enough to carry in a handbag, backpack or large pocket.

The ergonomic grip and smooth edges make it comfortable to hold, and the foldable design allows it to take up minimal space in your bag.
