The market for ultra-slim wireless power banks is expanding through the introduction of semi-solid and silicon-carbon battery technology designed for safety, longevity, and slim profiles.

Makerz Co., Ltd., a subsidiary of Keyence Corporation, launched the ‘SOLIDZ Power Bank Model QT’, an ultra-thin 6.8mm device. This model utilizes semi-solid batteries to reduce liquid electrolyte, aiming to prevent ignition during physical damage such as being pierced or crushed.

Following this, other manufacturers have introduced similar compact magnetic power banks. The UltraCharge Pro Slim Magnetic Power Bank 5K utilizes ‘BoostSolid Cell’ technology to provide increased charge cycles.

Xiaomi has further expanded this segment with new ultra-thin magnetic power banks utilizing silicon-carbon battery technology. Their 5,000mAh model features a 6mm thick aluminum alloy body and offers up to 15W wireless output for compatible Xiaomi devices. A larger 10,000mAh model (WPB1026S) measures 13.2mm in thickness and supports up to 45W wired output via USB-C. This larger model also includes battery health monitoring features, allowing users to view temperature, voltage, and operating status when connected to a computer.
