Xiaomi has launched a magnetic power bank thin enough to disappear behind a phone case, packing a 5,000mAh cell into a body just 6mm thick and 98 grams in weight. The device, officially showcased at MWC 2026 in Barcelona, has now rolled out across Europe, Australia, and Singapore, according to a report by Yanko Design [NEEDS VERIFICATION: exact regional launch date and India/US availability not yet confirmed].
What Makes It “Ultra-Thin”
Most magnetic power banks on the market sit somewhere between 10mm and 14mm thick once you factor in the coil and battery cell. Xiaomi’s version cuts that down to 6mm — closer to the thickness of a credit card stack than a typical portable charger. The trick isn’t a smaller battery. It’s a different battery chemistry entirely.
The Silicon-Carbon Battery, Explained
Xiaomi’s power bank uses a silicon-carbon battery with 16% silicon content, according to Yanko Design’s July 2026 gadget roundup. Silicon-carbon cells can store more energy per unit of volume than standard lithium-ion cells, which is what lets Xiaomi hit 5,000mAh without the usual thickness penalty.
This isn’t just a spec-sheet flex — it signals a broader shift happening across the battery industry in 2026, as more phone and accessory makers look to silicon-based anodes to shrink devices without shrinking capacity. [NEEDS VERIFICATION: Xiaomi has not published an official technical whitepaper on this specific cell; the 16% figure comes from third-party testing/reporting, not a Xiaomi press release.]
Where You Can Buy It Right Now
As of this month, the power bank is available in:

Pricing, exact retail availability by country, and whether it will launch in India or the US have not been confirmed. [NEEDS VERIFICATION]
Why This Matters for MagSafe-Style Accessories
The magnetic power bank category has grown crowded since Apple popularized MagSafe, but most entries compromise on either thickness or capacity to hit a price point. Xiaomi’s approach — leaning on cell chemistry rather than a smaller battery — suggests other manufacturers may follow suit rather than compete purely on price.
