Anker Nano Power Bank 10K 45W vs INIU Ultra Mini 10000mAh 45W

Both are 10,000mAh packs with 45W USB-C output, so charging speed is a wash. The Anker Nano wins on information and convenience: a smart color display shows remaining charge and status, and the retractable built-in cable means nothing to lose. The INIU Ultra Mini wins on ports and support: two USB-C plus one USB-A let it charge three devices at once, and it carries a 3-year warranty. The Anker has far more owner feedback (820 ratings vs 116), both sit at 4.7 stars. Pick Anker for a single-device daily carry; pick INIU if you juggle several devices or want the longer warranty.

• Choose the Anker Nano Power Bank if you want a built-in retractable cable, a display that shows exact battery level, and the most-reviewed option of the two.
• Choose the INIU Ultra Mini if you need to charge up to three devices at once or want a 3-year warranty with lifetime support.
