N35 was founded when founder Zheng Yi was trapped in a sudden lake crash for 66 hours while driving through Xijin Wulan Lake in northern Tibet. After this incident, he searched the domestic and foreign markets and found professional power equipment that did not meet the extreme environment, thus giving rise to the idea of developing a field power equipment for explorers to use in the extreme environment.
