Xiaomi’s new 10,000mAh 45W magnetic power bank is a masterclass in portable design, and a recent teardown by Battery Trading Network reveals the secret: high-density lithium-polymer cells from ATL. Balancing a slim 13.20mm chassis with a 10,000mAh capacity, this power bank packs 45W wired and 20W wireless charging, meeting the higher reliability demands of the new national power bank standards.
Inside, two ATL 436678B cells (4850mAh each) deliver a total of 36.77Wh of energy. This configuration is key to achieving such a lightweight, 196.3g profile without sacrificing capacity. As ATL is a core drafter of the GB 47372-2026 standard, their involvement underscores Xiaomi’s commitment to safety and quality. For premium magnetic power banks, high-density, reliable ATL cells are clearly becoming the industry benchmark.
