"Xiaomi is using a silicon-carbon battery with 16% silicon content, which is the kind of battery chemistry that allows for higher energy density in a slimmer package. That's how they've managed to squeeze 5,000mAh into something that resembles a metal business card more than a traditional power bank."
"The aluminum alloy shell has a smooth, understated finish, and the phone-facing surface uses fire-resistant fiberglass with an excimer coating for heat management. A photolithographically etched logo on the back adds a subtle detail that signals this product was designed with care, not just assembled to a spec sheet."
"It launched in Japan earlier this year at roughly $50, has since expanded to Australia, Singapore, South Korea, and Europe, and was officially showcased at MWC 2026 in Barcelona. The European pricing sits around €60 for the Glacier Silver and Graphite Black versions, with a slightly more expensive Radiant Orange option at €65."
Xiaomi has released the UltraThin Magnetic Power Bank 5000 15W, a remarkably thin power bank measuring just 6mm thick and weighing 98 grams—thinner than most modern smartphones. The device uses silicon-carbon battery chemistry with 16% silicon content to achieve 5,000mAh capacity in a compact design. The aluminum alloy shell features a smooth finish with fire-resistant fiberglass on the phone-facing surface and an excimer coating for heat management. Launched in Japan at approximately $50, it has expanded to Australia, Singapore, South Korea, and Europe with pricing around €60-€65. The power bank offers 15W wireless charging for Xiaomi 17 series devices, 7.5W for iPhones due to MagSafe limitations, and 22.5W via USB-C charging.
