Mankerlight was founded by our two flashaholics engineers who also addicted to outdoor recreation. We have experienced a lot of different flashlights and found that the Led flashlight market faced a big problem: homogeneity, similar appearance and similar circuit. So we decided to make something different and created Manker which means someone walking outside with passion and freedom in Chinese.
