Pocket-Sized 20000mAh Power Bank

The INIU P512 packs a 20000mAh lithium-polymer cell into a frame measuring 4.1 in by 2.8 in by 1.2 in. It targets travellers and daily commuters who need multiple phone charges without carrying a bulky brick.

Detachable Nylon Lanyard Cable

A built-in USB-C cord doubles as a woven nylon lanyard rated to outlast standard plastic by 3X. The unit also provides two additional USB-C ports so Apple users or multi-device owners can plug in without hunting for extra cables.

22.5W Fast Charge Output

The power bank delivers up to 22.5W, pushing a Samsung S25 to 70 percent or an iPhone 16 to 60 percent in 25 minutes. Thermal sensors throttle output to prevent overheating, so sustained peak power is not guaranteed for every session.
