나노 파워뱅크 (10K, 45W, 내장형 자동 감김 USB-C 케이블)

The retractable cable is the selling point for me — no more tangled mess in my bag, and it clicks back in cleanly every time. I’ve topped up my phone twice and still had juice left for my earbuds, which is perfect for a long day out.

The retractable USB-C cable is the reason I bought this, and it's genuinely changed how I pack — no more tangled cords in my bag. It topped up my phone from 15% to full during a layover, and the 45W speed felt noticeably quicker than my old brick.

I was skeptical a 10K battery could actually fit in my pocket, but the 45W charging speed made my phone go from 20% to full in under 45 minutes on a bus ride. The retractable cable staying flush against the unit is a small touch that makes a big difference when you're juggling bags.
