Rechargeable Portable Desk Fan 6.5 Inch 4000mAh 4 Speed LED Display Foldable Cordless

This is a foldable desk fan with a built-in 4,000 mAh rechargeable battery. It runs cordless on battery or plugs in via USB while charging. The LED display on the base shows battery level and current speed setting. Four speed settings, one button to cycle through them.

The fan folds flat for storage and travel. When folded, the blade and guard fold back against the base, reducing the profile enough to fit in a laptop bag side pocket or a carry-on. When open, the fan head tilts up to 180 degrees to point airflow where you need it.

Available in black, purple, white, and pink. Select your color from the option above before adding to cart.

Battery and runtime

The 4,000 mAh battery runs the fan for approximately 5 hours on high speed and up to around 20 hours on low speed. Actual runtime varies based on ambient temperature and battery age. The fan charges via USB and can also charge a phone or small device through its USB output port, though running both simultaneously will reduce fan runtime.

The LED display shows remaining battery as a percentage, so you can see when to recharge without guessing. Charging the fan from empty takes approximately 3 to 4 hours with a standard 5V 2A adapter.

Where this fan works well

Work from home desk. The LED display is readable in normal room lighting without being distracting. At low or medium speed, the fan runs under 40 dB, which is quiet enough for video calls. The foldable design means it stores in a drawer when not in use without taking up permanent desk space.

Bedside table overnight. The battery means no cable to manage while sleeping. At the lowest speed setting, the fan is quiet and produces steady airflow. The LED display dims during use and is not bright enough to disturb sleep in most situations.

Travel and hotel rooms. Hotel rooms vary widely in how well the AC works and where the vents point. Having a compact fan that charges from the same USB adapter as your phone removes the need to find an outlet. The folded size fits in most travel bags without difficulty.

Outdoor and camping. The battery runs the fan independently of any power source. At medium speed, expect around 10 to 12 hours per charge, which covers an overnight camping trip on a single charge at low speed.

What to know before buying

This fan can output USB power to charge a phone or small device. It is not designed as a primary power bank. The output is 5V 2A, enough to charge a phone slowly. Using the charging output while the fan runs will shorten fan battery life accordingly.

The foldable hinge is the most frequently mentioned point in buyer feedback. Folding and unfolding daily over many months can loosen the hinge on fans of this type. If you keep it set up on a desk most of the time and only fold it for travel, the hinge holds up better than if you fold and unfold it every day.

Four speeds gives you more control than most fans in this size range. The difference between low and medium speed is noticeable in both airflow and noise. High speed is meaningfully louder than medium. Most people use medium for daily work and low for sleeping.
