In the ever-evolving world of mobile accessories, the quest for the perfect blend of portability and power continues. Xiaomi has just raised the bar with the release of its UltraThin Magnetic Power Bank, a device that shaves precious millimeters off its predecessor to become one of the slimmest magnetic battery packs on the market.
A Noticeably Slimmer Profile
The most immediate upgrade is in the design. Last year’s Xiaomi Super Slim Magnetic Power Bank 5000 measured a respectable 8.7 mm thick. The new model crushes that, coming in at a wafer-thin 6 mm (0.2 inches). To put that in perspective, it’s only a whisper thicker than the famously slender iPhone Air (5.6 mm). This makes it an incredibly discreet companion that adds minimal bulk when snapped onto your phone.
Charging Speeds: Wireless vs. Wired
Magnetically attaching to the back of compatible phones, this power bank offers convenient cable-free charging. For users of the latest Xiaomi 17 series, it supports up to 15W wireless charging. iPhone owners, however, will find their charging capped at the standard 7.5W. This places it behind newer Qi2-certified competitors like the Ugreen MagFlow, which can deliver up to 25W. Where the Xiaomi pack fights back is in wired charging: its USB-C port can deliver a faster 22.5W boost if you have a cable handy.

Broad Compatibility and Sleek Fit
Based on promotional images, the power bank boasts a clean, integrated look on a variety of flagship devices. It appears to align perfectly with the backs of the iPhone Air, iPhone 17 Pro, Google Pixel 10 Pro, and OnePlus 15, suggesting thoughtful design for a universal aesthetic.
Power and Safety Packed In
Don’t let the slim form fool you. Inside, Xiaomi has packed a high-density 5,000 mAh silicon-carbon battery, which should be sufficient for at least one full charge for most smartphones. Four LEDs provide a clear battery level readout, and a dedicated button offers control over when to start or stop charging.
Safety is a key focus. The power bank features an aluminum alloy shell with a smooth finish, while the side that attaches to your phone uses fire-resistant fiberglass. Xiaomi further claims ten layers of safety protection and the inclusion of dual NTC temperature sensors to actively monitor and prevent overheating during use.

Pricing, Availability, and Alternatives
Xiaomi has launched the UltraThin Magnetic Power Bank initially in Japan. It is priced at ¥7,980 (approximately $50.44) and is available for purchase through Amazon Japan and Xiaomi's official store.
As of now, Xiaomi has not announced plans for a wider global release. For customers in Europe and the UK seeking a similar solution, the previous generation Super Slim Magnetic Power Bank 5000 (8.7 mm thick) remains a readily available option.
