Nano Power Bank (12 W, sisäänrakennettu Lightning-liitin)

Didn't realize how much I'd use this until my phone hit 8% at a concert and I had nothing else. The built-in Lightning plug means no cable to lose, and it's small enough to just live in my jacket pocket. Charges slower than my wall brick, but for a panic top-up it's been perfect.

The built-in Lightning connector is so convenient — I just plug it straight into my phone, no cable needed. It’s small enough to slip into my work bag’s front pocket, and the 12W output got me from 20% to 60% during a quick lunch break.

I tossed it in my pocket before a long day out and never once worried about my phone dying. The built-in Lightning connector means no cable hunting, and it topped up my iPhone surprisingly fast for such a tiny brick.
