Xiaomi 6mm Magnetic Power Bank 5000mAh with 15W Wireless Charging
Xiaomi announced the Jinshajiang (Jinsha River) Magnetic Ultra-Thin Power Bank 5000 (15W) in China, a 6 mm-thick, 5000 mAh unit with 15W magnetic wireless charging and 22.5W USB-C wired output. It can power two devices at once and is priced at CNY 299. Global availability isn’t confirmed.
Xiaomi Power Bank 5000mAh: Specs and Features
- Name: Xiaomi Jinshajiang Magnetic Ultra-Thin Power Bank 5000 15W.
- Size/weight: 98.5 × 71.5 × 6.0 mm; ~98 g.
- Outputs: up to 15W magnetic wireless; up to 22.5W USB-C wired; supports dual-device simultaneous charging.
- Battery tech: Xiaomi’s “Jinshajiang” high-energy-density cell; same family used in Xiaomi 17 series with 16% silicon content in phones.
- Price: CNY 299 (≈ $42).
- Launch context: Announced alongside Xiaomi 17 series and other accessories during Lei Jun’s annual event.
Design, Charging Speeds, and Battery Cell
Xiaomi’s new 5000 mAh accessory focuses on pocketability: at just 6 mm, it’s markedly thinner than many earlier Xiaomi magnetic power banks sold globally at ~8.7 mm. The trade-off aims to keep a flat profile on modern phones while still providing a meaningful top-up.
Charging flexibility is a key pitch. The pad supplies up to 15W magnetic wireless charging for compatible phones, while the USB-C port can push up to 22.5W to a second device. Xiaomi and Chinese tech press say the bank can charge two devices at once (wired + wireless).
Xiaomi ties the slimness to its in-house “Jinshajiang” cell line. The company has been highlighting higher energy density silicon-carbon anode chemistry in its 17-series phones (citing 16% silicon content there). The power bank appears to use a phone-grade cell from the same family, which helps explain the 6 mm body.
Xiaomi’s Announcement
During Lei Jun’s annual talk, Xiaomi introduced a “newly designed magnetic power bank” with 5000 mAh capacity, 6 mm body, 15W wireless output, full compatibility with the iPhone 17 lineup, and a 299-yuan price.
What It Means for Buyers
For iPhone and Android users who prefer a flatter battery pack, Xiaomi’s 6 mm profile may be the draw. The mix of 15W magnetic charging and 22.5W USB-C keeps it useful beyond MagSafe-style phones handy for earbuds or a secondary handset.
What we don’t know yet: Xiaomi hasn’t announced global rollout. Historically, Xiaomi has sold different magnetic power banks outside China with slightly different dimensions and outputs, so the 6 mm model may stay China-only or arrive later under a different name. We’ll track listings on Xiaomi Global and regional stores.
