Can it charge a laptop?

Only small, low-power USB-C devices. At 45W it falls short of most laptops, which typically want 60W or more, so expect slow charging or none at all.

How many devices can it charge at once?

One. There is a single USB-C port, so you cannot top up a phone and earbuds together.

About two for a typical phone, less if you use fast charging or charge a larger device.

Check the box contents before buying. Many power banks in this class ship without a cable or wall charger.

The remaining battery level as a percentage, so you know when to recharge it.

Yes. At 10000mAh it is well under the usual carry-on limit for lithium power banks, but it must go in the cabin, not checked baggage.
