1. Electric Two-Wheelers: The Mainstream Urban Mobility
Electric two-wheelers have become a highly popularized, mainstream mode of transportation, generally categorized into three types: electric bicycles(E-bikes), electric light motorcycles, and electric motorcycles. Among these, E-bikes serve as a low-carbon, highly convenient short-distance mobility tool, widely utilized in personal commuting, food delivery, and shared mobility sectors.
According to industry statistics, by the end of 2023, the number of electric two-wheelers in China exceeded 400 million units, surpassing the country’s total automobile ownership of 310 million.

2. Urgent Need for Charger Optimization
With the rapid growth in electric two-wheeler usage, frequent charging-related fire incidents have raised severe safety concerns. Consequently, multiple provinces have strictly prohibited e-scooters and batteries from entering elevators and residential buildings.
As outdoor charging demand rises, dustproof and waterproof performance has become critical. However, traditional solutions often require larger enclosures to meet higher protection ratings, significantly reducing portability.
For users, prolonged charging times, low conversion efficiency, limited driving range, and safety hazards remain major pain points.
To stand out in an increasingly competitive market, charger manufacturers must continuously innovate and upgrade product quality to address these evolving consumer demands.
