[0002] Flashlights have the following problems in daily use:

[0003] (1) When using the navigation function continuously, the battery life of traditional lithium battery-powered smart flashlights is significantly shortened due to the continuous power consumption of the positioning module, making it difficult to meet the needs of long-term outdoor operations.

[0004] (2) Existing aluminum-air battery systems have low integration with electronic devices and cannot effectively match the intermittent high-power output characteristics of smart devices;
