Doesn't the Macbook require a certain minimum power to be available before it will start trying to charge though. IE if I plug it into an old .5A USB charger would it try to charge off the 2.5W? That's most of what I meant when I was talking about providing enough power.

It charges quite happily off the 3W max which is standard on most non-power-delivery USB-C ports (inc Apple's, iirc)
