Xiaomi Launches Ultra-Thin 10,000mAh Magnetic Power Bank With 45W Charging
Xiaomi has officially introduced its Jinshajiang Ultra-thin Magnetic Power Bank 10,000mAh 45W in China, following a successful crowdfunding campaign. The new accessory doubles the battery capacity of its predecessor while incorporating faster charging capabilities and advanced safety engineering designed to mitigate thermal risks.
Xiaomi's Jinshajiang power bank supports magnetic wireless charging for phones such as the iPhone 18 Pro and Google Pixel 11, while supporting PD 3.0, QC, and PPS protocols.
The release builds directly upon Xiaomi's 5,000mAh ultra-thin magnetic power bank launched earlier in the year. Although maintaining a compact footprint, the new model measures 13.2mm in thickness to accommodate the larger cell, compared with the 6mm profile of the smaller variant.
Battery Specifications and Charging Performance
The power bank utilizes a high-density silicon-carbon battery yielding a 10,000mAh total capacity, according to company disclosures. It supports wireless magnetic charging at up to 20W, representing an upgrade over the 15W ceiling of its smaller sibling.
For wired connections, the built-in USB Type-C port delivers power delivery up to 45W. This output level enables the accessory to charge a wide array of compatible mobile devices, tablets, and lightweight laptops such as the MacBook Air. Furthermore, the unit supports multiple fast-charging protocols including Power Delivery 3.0, Quick Charge, and Programmable Power Supply.
Safety Engineering and Diagnostics
Addressing consumer safety concerns surrounding high-density lithium cells, Xiaomi has integrated robust protective mechanisms against overheating, internal short circuits, and potential fires. The device reportedly satisfies rigorous testing protocols, including needle penetration trials and hot-box evaluations under extreme thermal stress.
Pricing and Global Availability
The Jinshajiang Ultra-thin Magnetic Power Bank is priced at 399 yuan, equivalent to approximately $59.62, and is currently available in silver and dark gunmetal color finishes across retail channels in China. Xiaomi has not yet disclosed official timelines or pricing for international markets, including India, where previous models have seen selective releases.
Xiaomi offered the Jinshajiang Ultra-Thin Magnetic Power Bank 10000 45W during crowdfunding in China at 349 Yuan (~$48), compared to a suggested retail price of 399 Yuan (~$55).
How to compare magnetic power banks safely
A 10,000mAh capacity rating normally describes cells at their nominal internal voltage, not the amount of charge a phone receives after wireless-transfer losses. Magnetic alignment, heat and charging protocol can significantly alter real-world speed. The advertised 45W figure should be checked for the specific wired or wireless output mode, compatible device and supported cable; it should not automatically be interpreted as sustained magnetic charging power. Customers should also check weight, phone-case compatibility, battery certifications and any airline restrictions before travelling. Independent efficiency and temperature testing will tell buyers more than a claim that a product is unusually thin.
