"iPhone 15 Pro can be charged 10.8 times or the MacBook Air M2 can be charged 15 times." That doesn't seem right... A quick search shows a lot of sites claiming a MacBook Air M2 has an around 4700mAh battery, but that seems too tiny to be true. Apple is giving a figure of 52.6 Watt Hours, which is a better measurement, but it would indicate this power bank can only charge a MacBook Air M2 just 3 times, not 15 as claimed.
