In Chengdu, shared power banks are ubiquitous and can be found in nearly every type of commercial establishment throughout the city. These portable battery rental stations are commonly located at the counters or entrances of restaurants, cafes, shopping malls, hotels, and office buildings. They are also frequently available in high-traffic public areas such as metro stations, airports, train stations, and popular tourist districts like Chunxi Road or Jinli Ancient Street. Leading providers such as Meituan, Energy Monster, and others operate hundreds of thousands of these units across the city, allowing users to locate the nearest station easily through mobile apps like WeChat or Alipay. The system is designed for maximum convenience, enabling travelers to rent a power bank from one location by scanning a QR code and returning it to any other compatible station once their device is charged.
