As the adult products industry continues to grow, egg vibrators and other intimate devices are evolving toward smarter and more advanced designs. Consumers demand stronger vibrations, longer battery life, and enhanced safety for a better user experience. Since the battery is the core power source of egg vibrators, its performance directly impacts the product’s competitiveness in the market.

Market Pain Points: Current Issues with Lithium Batteries
- Short Battery Life Affects User Experience: Many egg vibrators use small-capacity batteries (100mAh-300mAh), lasting only 30-60 minutes in high-intensity vibration mode.
- Slow Charging Speeds Are Inconvenient: Some vibrators take over two hours to fully recharge, limiting usability.
- Safety Concerns: Low-quality batteries may overheat, swell, or leak, causing potential risks.
- Size Constraints Affect Product Design: Standard battery sizes may not fit compact designs, affecting functionality and aesthetics.
