Can I use Anker 622 charger to wirelessly charge my iPhone 11 Pro?

The charger you bought is designed for MagSafe and your iPhone is NOT MagSafe. MagSafe didn't arrive for iPhone until iPhone 12 and newer models. It will likely charge, but it will NOT attach magnetically to your phone, so it won't be optimal for an iPhone 11 Pro.

Apple does not test other products for compatibilty.

Anker's literature claims that you can do this, so you would have to refer any additional questions to Anker Support, or wait to see if another user has the used the Anker product that you are asking about with an iPhone 11 Pro.

May be a very long wait.

You can try that, but it's not a guarantee it will work, even with a MagSafe case as iPhone 11 is NOT a MagSafe designed iPhone.

This might help clarify things a little more. Kind of a "yes and no" answer.
