How many times can it charge a phone?

With 10,000mAh it refills most phones about twice, less for large phones or if you charge two devices at once.

No. It has two USB-A outputs only, so you need a USB-A cable for your phone and a micro-USB or similar cable to recharge the bank.

Can it charge two devices at once?

Yes, both USB-A ports can be used together, though charging two devices splits the output and drains it faster.

Yes. At 10,000mAh it is well under the usual carry-on limit for lithium batteries, but keep it in your cabin bag, not checked luggage.

No. Output and input are standard speed, so it is slower than fast-charging power banks.

The power bank and a short charging cable; check the listing for the exact cable type, since a wall charger is not included.
