Does it charge at full 15W on iPhone?

Yes, on Qi2-compatible iPhones it charges wirelessly at up to 15W. Older or non-MagSafe phones fall back to slower rates.

How many charges will it give my phone?

Expect about one full charge for a typical iPhone. Wireless charging loses some energy to heat, so real-world output is below the rated capacity.

Only if the phone supports Qi2 or has a magnetic ring case. Otherwise it can still charge wirelessly, but it will not snap on or hit 15W.

It is a fair price for a Qi2-certified magnetic bank from Anker. If you mainly want capacity per dollar, a wired Anker bank gives more for less.

Yes. The magnet holds the phone in place, so you can keep using it, though the phone will run warmer.

The power bank and a USB-C cable. You supply your own wall adapter for recharging the bank.
