Ask HN: What do you think about wireless charging?

Since I got a gift of a pair of earbuds with wireless charging, I have been thinking about the energy loss happening during the process.

As far as I can tell, wireless charging is (optimistically) 70-80% efficient. Now I agree it hardly matters for small/niche earbuds, but with Apple moving their iPhones [0] to fully wireless Qi charging. I think a 30% waste on that scale (once the ecosystem fallows) could become a problem.

What do you think about that waste? Or am I over-blowing the issue?
