Handheld Fan Black 1. Last year, we listened to customer feedback and analyzed the issues with existing handheld fans on the market, leading us to develop an improved handheld fan. Addressing the issue of battery level display, we designed an LED display that accurately shows the battery level down to 1%. You can see the remaining battery at a glance, making it easy to know when to recharge, perfect for outdoor activities. 2. Our handheld fan uses a high-performance brushless motor, which provides more stable rotation than ordinary motors, continuously generating a gentle breeze to keep you cool. Enjoy a refreshing summer with a comfortable breeze all over your body this summer. 3. The portable fan has a compact design, small enough to fit in a bag, making it easy to carry. It's suitable for various outdoor activities such as sports events, fireworks displays, leisure activities, commuting, and outdoor adventures. The portable fan can be adjusted up and down 180°, allowing you to direct the cool breeze to any part of your upper body as needed. 4. The handheld fan incorporates a durable polymer lithium battery with a 4000mAh capacity, allowing for up to 15 hours of continuous use, sufficient for daily use. The LED display clearly shows the battery level, so you won't run out of power unexpectedly.
