Key Product Features & Innovations

• Upgraded 5000mAh Battery Cell: Experience industry-leading battery life. The high-capacity cell delivers up to 17.5 hours of continuous breeze on Speed 1 and roughly 3.5 to 4 hours on maximum Turbo mode—ideal for all-day outdoor events, festivals, or commutes.

• Real-Time Smart LED Screen: Track your battery precisely. The integrated center-mounted LED display dynamically toggles between showing your exact remaining battery percentage (0–100%) and your active wind speed level (1–5).

• 5-Speed Turbocharged Airflow: Adapt your airflow instantly. Easily switch between a quiet, low-speed breeze for air-conditioned indoor spaces and a high-velocity turbo blast to cool off fast under direct sunlight.

• Low-Noise Brushless DC Engine: Keep your cooling discreet. Built with a premium brushless motor base, the fan reduces mechanical friction and internal vibration, running quietly below 40dB on lower speed settings.

• Universal Type-C Fast Charging: Top up quickly anywhere. The side-mounted USB Type-C port supports versatile charging from power banks, laptops, or standard smartphone wall adapters.

Frequently Asked Questions (FAQ)

Q: What is the main difference between the Life4 3600mAh and this 5000mAh version?

A: Yes! The 5000mAh lithium-ion battery capacity equals roughly 18.5 Watt-hours (Wh), which is well below the standard TSA and international airline limit of 100Wh for portable battery devices. Simply pack it in your carry-on bag (not checked luggage).

Q: Does the fan come with a desktop stand or lanyard?

A: Yes, the packaging includes an anti-drop wrist lanyard that loops securely into the bottom base notch, as well as a flat bottom surface on the handle so you can set it upright on a desk or table.
