Xiaomi continues to surprise the market with innovative solutions in portable charging devices. The new magnetic external battery model WPB0507S is already on sale in China and promises to become a real hit thanks to its outstanding characteristics and affordable price.
Technical Specifications and Design
The new Xiaomi powerbank impresses with its compact dimensions while maintaining impressive capacity. The device measuring 102 x 69.6 x 8.7 mm houses a 5000 mAh battery, making it one of the thinnest solutions in its class.
The body is made of aluminum alloy with fiberglass elements, providing an optimal combination of strength and lightness. Such construction not only looks premium but also guarantees device durability during daily use.
Revolutionary Energy Density
The main technical achievement of the new powerbank is the record energy density of 734 Wh/l. This is 12.9% higher than the previous generation, made possible by using a modern lithium-cobalt oxide element.
Such high energy density allowed Xiaomi engineers to create a truly compact device without sacrificing battery capacity. This is especially important for users who value portability of their gadgets.
Multifunctional Charging
The powerbank supports both wireless and wired charging. Wireless charging works with power up to 15W supporting 5W, 7.5W, and 10W levels for compatibility with various devices. Wired charging through USB-C port provides up to 22.5W power.
A unique feature is the ability to simultaneously charge two devices: one via cable, another wirelessly. This makes the powerbank an ideal solution for users with multiple mobile devices.
MagSafe Magnetic Mounting
To ensure reliable attachment to MagSafe-compatible devices, a system of 17 neodymium N52 magnets with 10N attraction force is used. This guarantees stable connection even during active phone use while charging.
Magnetic attachment is not only convenient to use but also eliminates accidental device disconnection, which is especially important for wireless charging.
Cooling System and Safety
Xiaomi engineers paid special attention to the device's thermal operating mode. The powerbank is equipped with an advanced cooling system with a graphene heat spreader area of 826 mm², which effectively dissipates heat from active components.
Two NTC thermal sensors monitor device temperature 12,000 times per minute, providing precise thermal condition monitoring. This allows maintaining optimal operating temperature and extends battery life.
The safety system includes nine protection functions, including protection against overheating, overcharging, short circuit, and other potentially dangerous situations.
Durability and Reliability
The durability of the new powerbank deserves special attention. After 300 complete charge cycles, the device retains more than 80% of original capacity, indicating high quality of power elements used and thoughtful charge management system.
Such durability indicators mean that the powerbank will maintain its efficiency throughout several years of active use, making it a profitable long-term acquisition.
Price and Availability
With all its impressive characteristics, the new Xiaomi magnetic powerbank has a very attractive price of just $23. This makes it one of the most affordable MagSafe-supported solutions on the market.
Currently, the device is available for purchase in China. Information about international sales has not been announced yet, but considering Xiaomi's product popularity, we can expect the powerbank to appear in other regions soon.
