You must be using a very old Apple AC-to-USB plug.
For several years now, Apple has made available a very small plug who can deliver 5W (5V@1A) who should be enough for your need.

Very old AC-to-USB plug? Nope, it's the one that came with my iPhone 7....
But I misread, very small print. It is indeed 1A. I'll edit the OP. Thanks.
