Product Features
World’s Thinnest Class at Just 6.9mm
With a capacity of 5000mAh, the MagOn Prime Ultra Slim 5000 achieves a thickness of only 6.9mm. This ultra-thin design is a result of MATECH’s commitment to slimness, making it a world-class Qi2-compatible mobile battery. Its minimalist design is crafted to integrate seamlessly with smartphones, fitting easily into pockets or bags without adding bulk.
Lightweight at Approximately 99g
Weighing only about 99g, equivalent to two eggs, the device minimizes strain on the wrist even during prolonged use. It can function as a MagSafe charger at home and a mobile battery on the go. Despite its ultra-light design, it houses a 5000mAh capacity, capable of charging a smartphone approximately once.
Optimal 5000mAh Capacity
The 5000mAh capacity provides approximately one full charge for a smartphone, making it ideal for daily activities such as commuting, school, cafe visits, shopping, or day trips. The design philosophy prioritizes a balance between essential power and maximum slimness, aiming to create a mobile battery users will want to carry daily.
Qi2-Compatible for Up to 15W Fast Wireless Charging
Supporting the latest wireless charging standard, Qi2, the battery delivers up to 15W fast charging, approximately double the speed of conventional Qi1 (up to 7.5W). This enables stable magnetic wireless charging for both iPhones and Android smartphones.
Real-time Display
A real-time display shows the remaining battery percentage in 1% increments. When charging the unit itself, it also displays the time remaining until a full charge and the charging status. This immediate feedback helps alleviate concerns about battery depletion. The display’s refined design enhances the daily charging experience.
Strong Magnet for Stable Charging
Equipped with high-performance neodymium magnets, the battery securely attaches to smartphones, preventing displacement and ensuring stable wireless charging. This feature provides peace of mind during travel or when operating the phone with one hand.
Custom-Designed Lithium Polymer Battery
To achieve its ultra-thin profile, the MagOn Prime Ultra Slim 5000 incorporates a specially designed lithium polymer battery. Unlike generic cells, this customized thin cell enables a slim form factor akin to that of a smartphone. This design reflects MATECH’s philosophy of balancing thinness with practicality.
