Which is better for a full weekend trip?

The INIU. Its 10,000mAh holds about two phone charges, while the Anker's 5,000mAh covers roughly one.

Which is easier to carry every day?

The Anker. It is smaller and has a built-in plug, so it slides into a pocket with no cable.

Do both fast-charge an iPhone?

Both top out at 22.5W over USB-C, which is enough for fast charging on USB-C iPhones. The Anker also lists Apple charging support.

Is the Anker worth the extra money?

Only if the built-in plug and LCD matter to you. At $29.99 versus $19.99, the INIU gives twice the capacity for less.

Which lasts longer between charges?

The INIU, by capacity: 10,000mAh versus 5,000mAh. Expect about twice the runtime for the same device.

Can the INIU charge small gadgets safely?

Yes. It has a trickle-charging mode for earbuds and other low-power devices. The Anker has no equivalent mode listed.
