JISULIFE Handheld Fan Pro1S portable metal fan — Pro1S model, 5000mAh battery & up to 40H runtime

JISULIFE Handheld Fan Pro1S is a compact, metal-bodied portable fan that delivers powerful adjustable airflow with up to 40 hours of runtime and a clear digital display.

Engineered for travel, daily commutes and outdoor activities, the Pro1S pairs a three-phase brushless motor with a 5000mAh battery to produce strong, efficient cooling from a pocket-sized body. A stepless scroll switch lets you fine-tune speed across 100 levels while an 18W fast-charge system and digital battery readout keep you informed and ready. The cylindrical metal-finish housing and included accessories (storage bag and lanyard) make this fan a premium, giftable alternative to flimsy plastic models.

How strong is the airflow and what does that mean for cooling?

The Pro1S reaches a peak wind speed of about 9 m/s and a motor speed up to 9,700 RPM, producing noticeably stronger air than standard personal fans. That translates to faster, more consistent cooling whether you’re outdoors, at your desk, or commuting.

• Brushless three‑phase motor for sustained high output
• Max wind speed around 9 m/s for quick cooling
• Top rotation roughly 9,700 RPM — nearly twice typical handheld fans

How long will the battery last and how quickly does it recharge?

The Pro1S features a 5,000 mAh battery that supports a wide runtime range, depending on selected speed. With 18W fast charging, you can reach full capacity in 2–3 hours and get anywhere from about 3.5 hours at the highest settings up to approximately 40 hours at the lowest.

• 5000mAh battery for extended operation
• 18W fast charge via included USB‑A to USB‑C cable
• Runtime varies: roughly 3.5 hours (max) to 40 hours (min)

Can I control noise and airflow precisely for different situations?

The scroll switch offers stepless adjustment across 100 levels so you can precisely balance airflow and sound. Note that higher speeds produce greater noise — the fan ranges roughly from 53 dB at low settings to about 80 dB at maximum.

• Stepless scroll control from level 1 to 100 for customized comfort
• Low-speed operation suitable for offices and quiet spaces
• Higher speeds designed for outdoor use where louder operation is acceptable

What conveniences and protections are built in for travel and daily use?

The Pro1S was designed with portability and peace of mind in mind: a compact 6.3 x 2.44 x 2.36 inch frame, metal-feel finish, digital display for battery and speed, plus accessories and a one-year warranty. It ships partially discharged for safe transport, so remember to fully charge before first use.

• Compact, pocketable size (6.30" x 2.44" x 2.36") and 9.88 oz weight
• High-definition digital screen shows speed and remaining power
• Includes storage bag, anti-lost lanyard, USB‑A to USB‑C cable, and manual
• One-year warranty and customer support for product issues

Who this is for: The JISULIFE Handheld Fan Pro1S suits commuters, travelers, festival-goers and anyone who wants a dependable, high-performance portable fan with a premium metal finish. Choose it if you need precise speed control, long battery life, and a compact design that fits in a bag or pocket — especially useful for outdoor sports, warm commutes, or as a stylish gift for friends and family.
