Which is better for charging a laptop?

Both top out at 45W over USB-C, which is enough for a phone, tablet, or thin laptop but slow for a larger one. The Anker adds a built-in cable and a display; the INIU is cheaper.

Is the Anker Nano worth the extra $10?

If you value the retractable cable, color display, and pass-through charging, yes. If you already carry a USB-C cable, the INIU delivers the same 10,000mAh and 45W for $19.99.

Which one is smaller and lighter?

The INIU is sold as an ultra-mini pack and is the smaller, lighter option. The Anker measures 3.21 × 1.99 × 1.42 in and weighs 0.51 lb, partly because of the built-in cable mechanism.

Can both charge an iPhone 16 Pro fast?

Yes. Both output up to 45W over USB-C, and Anker states its pack charges an iPhone 16 Pro to 50% in 27 minutes. The INIU's 45W rating should give similar results with a USB-C to USB-C cable.

Do either support pass-through charging?

The Anker lists pass-through charging, so it can power a device while it recharges. INIU does not list it for this model, so do not count on it.

Which has a better warranty?

INIU typically backs its power banks with a 3-year warranty, longer than Anker's standard 18 to 24 months. Confirm the terms at checkout, since they can vary by seller.
