The only 10,000 mAh phone bank in this comparison whose maker states a per-phone figure for the iPhone 17 line (40 W) and for 45 W Galaxy models, with a retractable USB-C cable so there is nothing extra to carry.

Compared side by side
The Anker Nano Power Bank appears in this table next to models from other brands:
Who it's for
iPhone 17, 17 Pro and 17 Pro Max owners, and Galaxy S23+/S24+/S25+/S26+ and Ultra owners, who want the fastest wired charge from one pocket bank used with the phone alone.
Caveats
- The 45 W / 40 W figure applies with one device on the USB-C cable or port; two devices share 22.5 W (15 W + 7.5 W), below Apple's 18 W fast-charge threshold on both outputs
- iPhone 14 and earlier need a USB-C to Lightning adapter, not included
- Gigazine measured 34-36 W into a Pixel 10 Pro XL and a 160-minute recharge at 29 W input
