Jonukich Unveils Ultra-Thin 8mm, 8000mAh Magnetic Mobile Battery for Enhanced iPhone Convenience
Jonukich has introduced a new 8000mAh magnetic mobile battery, meticulously engineered to be just 8mm thick, prioritizing seamless integration with iPhones. To celebrate its launch, a special limited-time 80% discount campaign is underway, offering the product at ¥2,999 starting March 5th.
Pursuing “Thinness” That Doesn’t Compromise Smartphone Convenience
As smartphones become more advanced, mobile batteries have become indispensable. However, common issues such as being “heavy,” “bulky,” or “difficult to operate while charging” often arise. Jonukich addressed these inconveniences by focusing on developing a mobile battery that is both ultra-thin at 8mm and boasts a large capacity of 8000mAh, ensuring it feels natural when attached to the back of an iPhone.
Key Features of the Product
1. Amazingly Compact Design: 8mm Thickness, 105g Weight
The slim body allows it to fit comfortably in pockets or small pouches. Even when attached to an iPhone, it can be operated easily with one hand, making it suitable for various scenarios from daily commutes and school to travel, business trips, and disaster preparedness.
2. Stable Wireless Charging with Powerful Magnets
Equipped with strong MagSafe-compatible magnets, the battery securely attaches to the back of iPhones, from the iPhone 12 series to the latest iPhone 17 series, preventing slipping or falling during charging. This eliminates the hassle of plugging and unplugging cables, offering a smart charging experience.
3. Up to 20W Fast Charging and Broad Compatibility
The USB Type-C port supports up to 20W PD (Power Delivery) input/output, while wireless charging achieves a maximum output of 15W. It is capable of fast charging not only iPhones but also Android devices, wireless earphones, and a wide range of other devices.
4. Visual Status with “LED Indicator” and Original Design
Four LEDs display the remaining battery level, and a unique “triangle light” indicates the charging status with different colors (blue: magnetic charging, red: fast charging, purple: when both are used). This light also doubles as a strap hole, enhancing portability.
5. High Safety and a “3-Year Long-Term Warranty”
The product has acquired PSE certification. It incorporates a proprietary heat dissipation plate, high-quality alloy materials, and AI temperature control technology to suppress heat generation during charging. Furthermore, a 3-year long-term warranty is provided to ensure peace of mind for users.
