Can it charge a laptop?

Yes, from a wall outlet. The 45W USB-C output is enough for many thin-and-light laptops. On battery power it tops out at 20W, which is too low for most laptops.

How many charges does the 5,000mAh battery give a phone?

Roughly one full charge for a typical phone, less after conversion losses. Treat it as a top-up battery, not a multi-day pack.

Does it charge itself while plugged in?

Yes. Plugged into a wall it charges connected devices and refills its own battery at the same time.

Can it charge two devices at once?

Yes, through its two USB-C ports. Expect the 45W to be shared when both ports are in use.

Does it come with a cable?

It ships with a USB-C cable. You supply the wall outlet; the plug is built in and folds flat.

Is it allowed in carry-on luggage?

Yes. At 5,000mAh it is well under airline power bank limits, and the foldable plug makes it easy to pack.
