Application: This mobile phone pedometer requires only a slight hand movement and will continue to swing from side to side, suitable for most pedometer applications.
It can count steps with two mobile phones simultaneously, doubling the efficiency, and is compatible with all mobile phone sizes.
High-quality, high-speed bearings ensure truly continuous, wear-free, and smooth swinging. Even when unplugged, it can swing for extended periods without stopping.
Using electromagnetic principles, it simply plugs into a USB power cable for continuous oscillation, with low power consumption.
The entire process is silent, safe, and noise-free, environmentally friendly, and energy-saving, producing no pollution—you can even brush your teeth at midday.
