【Mini-sized】Collaborating with leading battery energy labs, we analyzed over 10,000 cell types over 2.5 years to develop a new high-energy, ultra-compact battery cell. Our product passed all 28 safety tests with flying colors, maintaining over 80% battery health after 3 months of charge-discharge cycles. With an 80% increase in density, our power bank is now 30% smaller than others with the same capacity.
【Safe, Powerful】features an intelligent AI chip for automatic temperature control, executing 200 protections per second, reducing overheating risks by 90% for a safer user experience. Built-in smart circuitry ensures protection against overheating, over-voltage, overload, short-circuit, and overcharging.
【Handy Stand】ZZI surveyed 2,000 individuals and discovered that 30% prefer phone cases with brackets for easier screen viewing during work. A significant 70% always carry a power bank when going out. From this data, we concluded that a power bank with a bracket feature is essential. After five months of research and development, we introduced the N7 power bank with a telescopic bracket, designed to free your hands when needed. Following two months of user testing by nearly 1,000 participants, the N7 received unanimous positive feedback.
