REMAX RS-SF27 4000mAh Foldable Mini Fan With Semiconductor Ice Cooling
Beating the heat on a crowded bus, at your office desk, or during a power cut just got easier. The REMAX RS-SF27 foldable mini fan uses semiconductor ice cooling technology to give you a genuinely cold breeze the moment you turn it on, not just moving warm air around like a standard portable fan.
Backed by a 4000mAh battery, this REMAX fan runs for up to 13 hours on a single charge, so it easily gets you through a full workday, a long commute, or an outdoor event without needing a recharge. A smart dot matrix display keeps you informed of the exact battery percentage and wind speed at a glance.
Its 90-degree foldable, 3-in-1 design switches between a handheld fan, a desktop stand, and a neck-hanging cooler in seconds, making it one of the most versatile personal fans you can carry in a bag or pocket.
Key Features
Semiconductor Ice Cooling: A built-in ice-magnetic plate drops surface temperature rapidly on contact, giving you an instantly cooling sensation instead of a warm recycled breeze.
4000mAh Long-Lasting Battery: High-capacity battery delivers up to 13 hours of cordless runtime, so the fan keeps up with a full day out or an entire shift at work.
Smart Dot Matrix Display: A clear digital readout shows remaining battery percentage and current wind speed, so you always know when it's time to recharge.
5 Adjustable Speed Levels: Choose anything from a whisper-quiet breeze to a powerful 5m/s airflow, letting you match the fan to the room, the weather, or your mood.
90-Degree Foldable, 3-in-1 Design: Folds flat and converts between a handheld fan, a desktop stand, and a neck-hanging cooler, so one device covers your desk, your commute, and your workout.
Type-C Fast Charging: Universal USB Type-C input means you can top up from a power bank, laptop, or wall adapter without hunting for a special cable.
Travel Safety Lock: A physical toggle lock stops the fan from switching on by accident inside a bag or pocket, protecting battery life and preventing awkward surprises.
Why Choose This REMAX Foldable Mini Fan
Most portable fans just push warm air around, but the REMAX RS-SF27 actually cools the air you feel thanks to its semiconductor ice cooling plate. Combined with a 4000mAh battery and five speed levels, it adapts to hot commutes, stuffy offices, and outdoor summer days alike.
The 3-in-1 folding design means you're not buying three separate gadgets — one compact fan works as a handheld cooler, a desk fan, and a hands-free neck fan. Add fast Type-C charging and a travel safety lock, and it's built for people who need reliable, portable cooling without extra hassle.
Best Use Cases
Daily Commute: Clip it around your neck on the bus, rickshaw, or walk to work for hands-free cooling.
Office & Study: Stand it on your desk during long work or study sessions when the AC isn't enough.
Outdoor Events: Stay comfortable at concerts, weddings, or sports days with up to 13 hours of runtime.
Travel: The foldable, lockable design makes it safe and compact to pack in a backpack or handbag.
