Xiaomi’s gaming-focused sub-brand Black Shark has unveiled the Black Shark Blade 2+ series in China, bringing updated versions of its compact magnetic power banks. While the overall concept remains the same, the newer models bring refinements in build and usability. A key change from the previous model is the magnetic surface, which now uses a UV-based coating designed to feel smoother and reduce the chances of scratching a phone’s back panel.

The series includes two capacity options. The 5,000mAh model focuses on portability, measuring about 0.8cm in thickness and weighing 105g. The larger 10,000mAh version increases thickness to 1.36cm and weighs 175g, offering more backup power while still maintaining a slim form factor. Both variants are built to attach directly to smartphones without adding much bulk.

Charging support is split between wireless and wired modes. Each model delivers up to 15W wireless charging. When using a cable, the smaller unit supports up to 18W output, while the higher-capacity version goes up to 22.5W. Support for multiple charging standards ensures compatibility across different devices.

Xiaomi is also emphasizing battery reliability. The company says the internal cells are similar to those used in Apple products, focusing on consistent output and longer service life. The units are rated for around 400 charge cycles, which is higher than typical compact power banks in this category.
The design follows a gaming-inspired aesthetic associated with the Black Shark brand. Sharp lines, visible capacity markings, and LED indicators give it a distinct look. A side button lets users quickly check the remaining charge, and a double press powers the unit off.
Magnetic attachment is handled by N52-grade magnets, which are intended to keep the power bank securely aligned with compatible devices during use. This ensures stable charging even while handling the phone.
Pricing in China starts at CNY 159 for the 5,000mAh model and CNY 189 for the 10,000mAh version. Xiaomi has not confirmed availability outside China, and a broader international launch does not appear to be planned at this point.
