Product Features
■ World's thinnest & smallest class. Ultra-thin 10.9mm design
The device features an ultra-thin, compact design measuring approximately 107.5 x 70 x 10.9mm. Despite being a 10,000mAh capacity device, it fits neatly into bags and pockets, feeling so compact you might forget you're carrying it. The 10.9mm thickness is significantly thinner than the diameter of a 1-yen coin. It can be comfortably carried in various scenarios such as cafes, bullet trains, airplanes, business trips, and travel. Weighing only about 180g, it allows for smart charging while on the move.
■ Charge even laptops with this one device
Supports a maximum output of 35W from a single USB-C port. It can charge a wide range of devices including MacBook Air, iPad Pro / Air / mini, iPhone, Galaxy, and Xperia. By handling everything from smartphones to laptops with a single unit, it helps reduce the number of chargers carried and promotes a smarter workflow.
■ 10,000mAh capacity for peace of mind all day
Despite its compact size, it is equipped with a reliable 10,000mAh capacity. It can charge an iPhone 17 approximately 1.8 times and a Galaxy S25 approximately 1.7 times. It provides peace of mind for long outings, from commuting and school attendance to travel and business trips.
■ Maximum 35W high-speed charging support
The USB-C port supports up to 35W output, enabling high-speed charging for a broad range of devices including iPhone, Galaxy, Xperia, iPad / iPad mini / iPad Pro, and some laptops such as the MacBook Air. It packs powerful charging performance that exceeds daily needs in a compact form.
■ Pass-through charging support
Allows simultaneous charging of the battery unit and a device like a smartphone. Even in environments with only one outlet, you can efficiently charge both the battery and your smartphone at the same time, reducing anxiety about finding your battery drained when you need it.
■ Cable becomes a strap
The included USB-C to USB-C cable functions as a strap when stowed. There is no need to carry a separate cable, allowing for immediate charging whenever needed, achieving a minimalist and smart way to carry the device.
■ Minimized size through custom-designed cells
PowerSlim 10000 uses custom-tailored battery cells rather than off-the-shelf options. By combining two 5,000mAh cells, it achieves a minimum-level size while maintaining a 10,000mAh capacity. Through thorough optimization of the internal structure, it pursues the ideal balance of 'thinness, lightness, and capacity.'
