RUNK: The world's smallest stylish mini portable power bank

For daily commutes most people don't need a 20,000mAh brick — just an emergency cell when the phone bottoms out. RUNK is built exactly for that: 3,000mAh and 62g in a car-key-sized body, yet with 30W fast-charging output, fitting into pockets, purses or even wallets. The charging cable is integrated so there's nothing extra to carry, with connector options for different phones. It even includes NFC for quick pairing and data transfer. The mech-style multi-faceted shell with a metal loop hangs on keyrings or bags, doubling as an accessory, while internal protection covers overcharge, over-discharge, short-circuit and overcurrent. Launched in July 2024, it drew 1,056 backers and raised $85,396 — 8,540% of its $1,000 goal.
